Greetings. In this article, we will look at the options for the ventilation system for the bathroom. In addition, I will tell you how these systems will build their own hands at home. The topic of the article is considerable interest, as the bathroom is the place where warm wet air and unpleasant odors are periodically accumulated.
If timely not equip an effectively functioning ventilation system, staying in such a room will be uncomfortable.
Consider options ventilation for the bathroom and toilet. It is divided into exhaust, supply and combined. In the exhaust scheme, the presence of a channel, outlining air, which contains an increased amount of moisture. The design of the supply ventilation is able to maximize the indoor pressure, to push the warm and wet steam and capture the atmospheric air. The combined device allows you to combine the air fence from the street and the output ventilation channel. Standard ventilation diagram used when equipping apartments in typical high-rise buildings - exhaust.
Ventilation schemes with which the air indoors will be fresh
Warm and wet air is a favorable environment for vital activity of various pathogenic organisms and primarily for mold. Excessive air humidity leads to rotting wooden parts in the finish and to the appearance of corrosion on metal parts of plumbing.
According to the degree of mechanization, the following types of the ventilation system are distinguished:
- Schemes of a natural passive action - the movement of air is carried out due to the difference in temperature and pressure inside and outside the room;
- Forced operation schemes - based on the use of electrical appliances that are transported by air.
On the principle of the system of ventilation system, the bathroom is divided into the following modifications:
- Exhaust scheme
The simplest thing in terms of implementation, but not the most effective solution. Such a scheme works due to the removal of exhaust air through the velocity or outlet. The problem is that without replacing the new air portion, it turns out the exhaust warm air outwards in small volumes.
- Supply-exhaust scheme
In this scheme, cold air is simultaneously served, for example, from under the door and proportionally removed the exhaust air through the outlet.
This scheme is preferable, as it allows to provide intensive air exchange. But special requirements are presented to the design of the supply and exhaust systems, since the errors lead to the appearance of drafts.
- Exhaust forced scheme
Comable option - is an intense in the toilet or in a bathroom with a built-in fan. The effectiveness of the circuit is slightly higher than that of the natural hood, but lower than that of the passive supply-exhaust system.
- Forced subtle-exhaust scheme
Effective option, since it is possible to adjust the tempo and intensity of the lead and air supply.
Such systems of this type are a modified version of the supply and exhaust diagram, where the lead and air supply is enhanced by electric fans. The fan is installed directly in the opening and turns on either in manual mode, or automatically, for example, when switching on light in the bathroom.
Such a solution has a significant drawback - with the fan off the fan, the ventilation intensity is twice as low as in the supply and exhaust systems of a natural type.
Components required to build ventilation systems
- Outer air intake grille
The external grille is designed to pass the air from the outside. The lattices are produced round and rectangular shape that, however, does not affect their operational qualities.
The outer grille performs the decorative function and the function of retention of dust. For these purposes, the lattice lamellas have a slope to the bottom.
- Inner grill
This device is installed on the air duct indoor and performs both decorative and barrier function. In place insects and dust penetrate the room through the air duct, a fine mesh is mounted with an injured side of the lattice.
As the ventilation system is used, the grid on the lattice is clogged with mud. Therefore, once every six months, the removable pad with the grille is dismantled, and the grid is washed away from contaminants or changes to a new grid, sliced \u200b\u200bby the required dimensions.
For greater functionality, the inner grille is equipped with moving lamellas, which turn around their axis and dosage passed air.
Round shape grilles are equipped with a movable insert, which rotates relative to the round removable nozzle. In one position, the slots in the movable insert coincide with the slots in the grid and ensures a full passage of air. In another position, the slots in the insert and in the outer cover do not coincide and the air does not pass.
Analogue of the described device in industrial systems is called an air valve. This is a shut-off valve, which is placed directly in the air duct. In industrial systems, the valve turns automatically when the fan is turned off, and in the household system, it is possible to overlap the air supply manually.
The choice of internal and outer decisions for the bathroom room is performed in accordance with the inner diameter and the configuration of the duct and in accordance with the aesthetic preferences. The most popular household grids are round with a landing size of 100 and 50 mm.
- Duct
In order to connect an inner grid with an external or in order to ensure the supply of the supply air, an air duct is needed. The air duct is a hollow tube with smooth inner walls and with the inner diameters of the cross-section, corresponding to the landing diameter of the solids used.
Industrial air ducts that are used to ventilate rooms from 300 m² and more are made of metal with a surface layer of thermo- and noise insulation. With the arrangement of the bathroom, there is no such need, and therefore PVCs or polyethylene pipes are applied.
In the market, plastic ducts are represented by rectangular and round modification. The shape and size of the cross section of the air ducts corresponds to the sector and the shape of the lattice.
Plastic pipes are distinguished by low thermal conductivity, so condensate fallout occurs in limited quantities. Anyway, in the diagram of the ventilation device in the outer part of the air duct, water drain holes should be provided.
- Fan
The selection of fans for the device of the forced system is performed according to their power and the landing diameter.
Fans are a compact electric motor with an impeller. All this node is integrated into the grille or adapted to install in the air duct.
In the prescribed form, the lattice with a fan appearance differs little from the strings used in passive systems. Most fans that can be purchased on the market or in special stores are designed to be used in the exhaust.
- Air Dryer
Household dehumidifiers do not relate to the ventilation system, but can optionally be operated in the room. That is, the desiccant will provide the optimal level of humidity, while ventilation refresh the exhaust air.
The use of household dryers allows you to solve the problem of condensate falling on the surface of the walls. As a result, the likelihood of mold appearance even with not effective ventilation is reduced.
Calculation of productivity
Two parameters of ventilation systems are regulated in the SNiP norms:
- the intensity of the air exchange is the volume of transported air;
- the multiplicity of air exchange is the number of cycles of the removal of the exhaust air.
To premise the bathroom, the average multiplicity rate is 4-8 cycles. The intensity of the air exchange for a separate bathroom is indicated within 25 m³ per hour. For a combined bathroom, this parameter is twice as much.
The above parameters are primarily refer to the fan. The intensity of the air exchange is determined by the fan power.
The multiplicity of equipment in low-cost systems of forced type is determined manually. That is, you yourself have to turn on the fan the required number of times at one time or another. In more progressive systems, the price of which will be higher, along with the fan, a special power unit is used to automate the air lead.
The device of the passive supply-exhaust system
Immediately note that for effective functioning natural ventilation interior doors must be installed as on the proposed scheme.
Due to the gap at the bottom of the web, it becomes possible intensive air exchange between ventilation throughout the house and hood in the bathroom. By the way, most modern interior doors are designed to meet an effective air exchange, and therefore are installed with the gap at the threshold.
Suppose interior doors in the house are installed correctly, which means you can start setting up the exhaust. Setting the drawing is performed in the top of the wall, below the ceiling line by 10-15 cm.
Mounting instructions Next:
- On the outer wall A private house is marked - the circle is drawn, the perimeter of which is 5 mm more than the perimeter of the air duct, which is supposed to be used for the passage of the wall;
- According to the placed perimeter, the wall is drilled through;
If the wall is concrete, it will correctly order a diamond cutting of concrete. Although the price is high, but the hole will have perfectly smooth edges and work will be performed quickly. If the wall is brick, you can drill yourself by doing through holes in the wall around the perimeter of the placed circle. After the holes are drilled, it remains to knocked out of the circle.
- We sweat dust out of the hole and wet the resulting opening with water;
- We insert a pre-prepared air duct into the hole and install in terms of the level, so that the external end of the pipe is located below the end, which is inside;
The inclination of the air duct when passing through the wall is required to provide natural condensate stock outward.
- In the interval between the edge of the hole and the pipe we apply a mounting foam;
- From the inside, the lattice is attached to the front end;
- From the outside, a tee is dressed on the pipe with one tap up to another down;
- On the bottom withdrawal, we dress the plug, drill in it through a hole with a diameter of 10 mm;
Through this hole in the cold season will be condensate. If the flow in winter is frozen, you will need to dismantle the cap and clean the drain.
- From the upper tap of the tearing, we drive the pipe up, as shown in this scheme;
- In the upper part of the pipe, the hole is covered with a smoking end - raincoat.
After the installation of ventilation is over, you will receive a productive system that will provide the bathroom with fresh air. The only drawback of such a solution is the likelihood of the formation of a draft on the path of air flow.
By the way, on this scheme you can see how the hoods of the bathroom are simultaneously connected to one pipe and from the kitchen without any damage to the air exchange.
Constructive exhaust system
In the diagram you can see an effective system forced selection of warm wet air throughout the house. For these purposes in the bathroom and the ducts connected to a powerful fan are equipped into the kitchen.
The selection of exhaust air is carried out through the air ducts located in the ceiling above the areas of the room in which the greatest accumulation of wet air is likely.
As in natural scheme Distribution of the exhaust air, the door at the bottom of the opening should have a gap in order to make a normal air exchange at the expense of circulating streams.
How to check ventilation efficiency
If the air flow is felt like a draft, then it's not worth worrying about the air exchange - it is more than sufficient.
In other cases, a lit match or a thin sheet of paper is brought to extract. By oscillation of paper or fire, you unmistakably determine how efficiently the hood is running.
By the way, the air ducts, especially if they are old, have the usual clogging. Therefore, the verification described above must be performed annually. If the air circulation intensity weakened, it's time to inspect the air duct and clean it.
Conclusion
Now you know what is the ventilation in the bathroom and the toilet, and how to do it yourself. I recommend to watch a video in this article. I am sure, if you wish, you can take advantage of the proposed instructions and make the air in the room the bathroom is more fresh. Ask questions on the topic in the comments.
Ventilation in the bathroom and toilet is an indispensable condition, since it is precisely in these rooms that the overall humidity of the air is increased and there are usually unpleasant odors. If the ventilation system is not installed or is not fully effective, then in the bathroom rooms not only the resistant smell will be maintained, but also a favorable microclimate will be created for the development of mold and fungus with which it is very difficult to deal with.
Everyone knows that steam and heated air rise up, and if they won't find the exit, most of the evaporations will sit on the surface of the ceiling and the top of the walls, where it is most often possible to see the black spots of the microflora colonies. We must not forget that any fungus is multiplied by disputes that are thrown into the air. Together with the air, then they are inhaled by households, and this can lead to the emergence of allergic reactions, diseases of the respiratory system, asthma and other serious illnesses.
Basically, the issue of carrying out effective stands up to the owners of private houses, as in high-rise buildings it is pre-layered in the project of the building, and Ventkanals are divided into the premises of the bathroom and kitchen. However, for the owners of the apartments, information can be useful - not always "full-time" ventilation system fully copes with its duties, and certain adjustments are required.
Types of ventilation systems
First of all, you should familiarize yourself with the existing system ventilation systems.
Ventilation systems are divided into two main types - natural and forced.
- Natural ventilation works only due to the free movement of air from the region increased pressure To lower, that is, without the use of special devices and devices. It is this type of ventilation that is designed in the apartments of most multi-storey houses. The size of the ventilation windows (trunks) in the bathroom and the toilet (individual or aligned) and in the kitchen, the configuration and the ability of ventilation rudders are designed to create a natural movement of air from residential premises with the desired amount of air exchange.
- Forced ventilation involves installing fans. Very often, this system is installed in the bathrooms and in the kitchens of private houses. However, some housing owners in high-rise buildings, wishing to improve the air ventilation, install the fan and in the conditions of the apartment.
In addition, the forced ventilation systems are divided, depending on their basic functions, the following types:
- Exhaust ventilation. In this system, the air rises under the ceiling with a fan is drawn and displayed on special channels into the street. Usually this scheme is used in a complex with a natural ventilation system. This is the most common option for private construction conditions.
For example, in this illustration, an option is presented through an air intake from the street, with its further compulsory tap across the kitchen and sanitary facilities.
- - In this system, the fan runs on the air supply, and its output for full cycle The ventilation is made naturally through the ventilation channels. In practice, in residential construction, such a scheme is infrequent - it is more important to create conditions for an effective air outlet outside in the required volume.
- The supply and exhaust system implies the injection of air into the room, and its forced removal of them. It is characteristic of bulk structures, for houses of a large area, in which the possibilities of natural tributaries and air outflow are clearly not enough.
Types of fans
Since the most effective for a residential building is precisely an exhaust ventilation system, with a natural influx of air through "clean" residential premises and its forced assigned to it through the kitchen and the bathroom, it is worth a few words to say about exhaust fans. They are divided into types according to the places of their installation - these are axial, channel, roof and radial.
- Axial wall (overhead) fans.
The axial fan consists of a housing having a type of cylinder, inside of which a wheel with console blades installed on the axis of the electric motor. When rotating, the blades are captured by air and activate its seat outlet.
This type of device is fixed in the ventilation channel window on the wall (or ceiling) of the bathroom or toilet. It is very simply mounted at the expense of a well-thought-out design, and it looks quite aesthetically, so it can be called the most popular for installation both in a private house and in the apartment.
- Channel fans.
Channel axial fans are used in household practice not so long ago and not so wide as overhead axial, since their self installation quite complicated. However, sometimes it is impossible to do without them, for example, in cases where the area of \u200b\u200bthe ventilated room is more than 15 m².
Channel fans are installed and in cases where they want to reduce the noise level from the device in the room of the bathroom or other premises of the private house.
This type of fan can be installed on different sections of the ventilation channel. It is placed in a special box case, or it can itself be a connecting element for two parts of the ventilation pipe. It is very important that free access is provided to the instrument, since it periodically needs to be cleaned and lubricated.
Air ducts in which channel fans are installed are three types - these are flexible, semi-rigid and hard.
Flexible channels are mounted easy enough, so they are choosing most often. However, they are less reliable, and their service life is much less than that of rigid or semi-rigid air ducts. An indental owner will definitely make a choice in favor of reliability.
- Radial fans.
The radial fan consists of a motor located on the axis of rotation of the wheel with blades, which is placed in a closed metal box having a characteristic spiral shape.
During the operation of the fan blade, it is started to rotate, capturing the air out of the room, which falls from the fan through the outlet opening of the casing into the air duct.
To install in residential buildings it is recommended to choose radial fans with blades-shovels bent back. Although they have several lower pressure indicators, such devices are distinguished by the best "linearity" in adjustments, the large working range and, most importantly, are not so noisy compared to fans with blades, bent forward.
Radial fans are well tolerated with high loads and are quite economical in operation.
- Roof fans.
As can be understood from the name of these devices, they are installed on the roofs of apartment and private houses.
The design of the roof fan includes such elements as the engine, a wheel with blades on the axis of rotation, vibration-insulating (damping) gaskets, an apparatus device.
The root fan may have axial, multilave or radial design. The latter is most in demand, since the least good and provides high performance with minimal electricity costs.
Ventilation forced systems can operate both automatically and in manual mode, have one level of pumping or several speeds.
- Unregulated ventilation has only two mode positions: "enabled" and "turned off".
- A more flexible system that has several velocities that are selected by the switch will be more flexible.
- The most economical fans with an adjustable speed of revolutions in which the rotational speed is attached to the blade wheel corresponding to the required current load on the system. Changing the speed occurs fairly smoothly, with the help of special automatic controls and control units.
Basic regulations and requirements for the organization of ventilation
It's time to move to the question of choosing the necessary and toilet. But immediately the main question will immediately rise about its most important characterization - performance, that is, the ability to pump a certain amount of air per unit of time.
In this aspect it will be difficult to understand if it is for starters not to get acquainted with the main regulations on the organization of ventilation in a residential building or apartment.
It is necessary to rely on this issue on the main guidelines - relevant sections and applications SNIP 41-01-2003 ("Heating, ventilation and air conditioning") and SNiP 2.08.01-89 * ("residential buildings").
According to the requirements of this document, a forced artificial ventilation system must be installed in the premises where it is necessary for sanitary standards, but natural ventilation, that is, a window or a fortage, there is no normal ventilation in them.
In order not to refer the reader to SNiP tables, the following is generalized information that will be required to calculate ventilation.
| Type of room | Ventilation rates | Notes | |
|---|---|---|---|
| Air inflow from the outside | Air extractor outside | ||
| Premises of residential zone | The multiplicity of air exchange is not lower than 0.35 times / hour, but at the same time the receipt of at least 30 m³ per person. | - | The calculation is based on the total volume of the apartment (at home) or on the number of real people |
| 3 m³ per 1 m² area of \u200b\u200bresidential premises | - | Calculation is carried out from the area of \u200b\u200bresidential premises at home | |
| Kitchen | |||
| · With electric stove | - | Not less than 60 m³ / hour | |
| · With 2 kontal gas stove | - | Not less than 60 m³ / hour | |
| · With 3 kontal gas stove | - | At least 75 m³ / h | |
| · With 4 kontal gas stove | - | Not less than 90 m³ / hour | |
| Bathroom | The inflow from the premises of the residential zone | At least 25 m³ / hour | |
| Restroom separate | The inflow from the premises of the residential zone | At least 25 m³ / hour | |
| The bathroom combined (bathroom + restroom) individual | The inflow from the premises of the residential zone | Not less than 50 m³ / hour | |
There is in SNiP, of course, norms and for more specific visits: dryers, ironing, isolated laundries and others. But in the context of this article, they are not particularly interested in us - we will talk about the average apartments or houses. You can easily be limited to the above values.
But why do we need to know the indicators of the supply of natural ventilation in the premises of the residential zone? And the fact is that the apartment or house should be considered as a single balanced "body". In order to be effective, and the bathroom, toilet and kitchen are constantly ventilated from the residential area, the exhaust devices installed in them should be able to cope with this task. Simply put, the volume of the drawn air can no longer be less than the incoming. There is such a notion as the air balance equation, and when selecting ventilation plants, it is necessary to strive for its maximum compliance.
Σqprit. \u003d Σqves.
Σqprit.- Required total air flowing with air ventilation.
Σqvit.- Required performance exhaust ventilation.
Failure to comply with this equality in one direction or another can cause unwanted consequences - stagnation of air, penetration of smells from the kitchen, and even worse - from the restroom, in the living rooms, the accumulation of dampness in the corners or on window slopes, unpleasant drafts and other negative phenomena.
Constantly fogging windows - a sign of poor ventilation of the premises.
The ever wet surface of the windows on the windows is half a misfortune, only an external sign is quite a serious problem. And what needs to be taken in this case - read in a special publication of our portal.
To decide S. the right part Our equation will have to carry out calculations for the necessary inflow of air.
The most correct approach will be the calculation in three parameters - according to sanitary standards for each living, by the multiplicity of air exchange in terms of the entire home or apartment, and according to the standards for each meter of the area of \u200b\u200bresidential premises. Then it will be left to compare the results obtained and select the maximum indicator - it will be the required value of air inflows for high-quality ventilation.
Well, then, based on the value obtained, it will be possible to move to the distribution of forced exhaust ventilation to achieve the desired equality.
For example, the settlement for the house with a total area of \u200b\u200b120 square meters.
Have problems calculate the area of \u200b\u200bthe room?
Typically, the area is easiest to take from the existing plan of the house. If there is no reason for some reason, but you have to calculate it yourself. In a special publication of the portal, various examples are considered - from the simplest rectangular premises to the rooms of an unusual complex configuration, and convenient online calculators are signed for quick and accurate calculation.
For convenience of calculations, you can make a small table:
| Rooms at home | Air inflow from the outside | Hood on the street | |||
|---|---|---|---|---|---|
| Other data and settlements | According to sanitary standards for living people | By the multiplicity of air exchange from the total area of \u200b\u200bthe room | According to the standards of 1 m² of useful area | Mounted minimum | Need in real conditions |
| Number of residence | 5 people | - | - | - | - |
| Living room | - | 21 m² | 21 m² | - | - |
| Sleeping 1. | - | 16 m² | 16 m² | - | - |
| Sleeping 2. | - | 14 m² | 14 m² | - | - |
| Children's | - | 17 m² | 17 m² | - | - |
| Dining room | - | 15 m² | 15 m² | - | - |
| Kitchen (gas stove 4 burners) | - | 12 m² | - | 90 m³ / h | 150 m³ / h |
| Parishion | - | 5 m² | - | - | - |
| Hall | - | 9 m² | - | - | |
| Corridor | - | 3 m² | - | - | - |
| Bathroom | - | 6 m² | - | 25 m³ / hour | 50 m³ / h |
| Sanusel | - | 2 m² | - | 25 m³ / hour | 50 m³ / h |
| Square in sum | - | 120 m² | 83 m² | - | - |
| Ceiling height | - | 3.1 M. | - | - | - |
| Volume in sum | - | 120 × 3.1 \u003d 372 m³ | - | - | - |
| Installed norm | 30 m³ / h | 0.35 times / hour | 3 m³ / 1 m² | - | - |
| Payment | 5 × 30 \u003d 150 | 372 × 0.35 \u003d 130.2 | 83 × 3 \u003d 249 | 90 + 25 + 25 = 140 | 150 + 50 + 50 = 250 |
| The need for standards | 150 m³ / h | 130.2 m³ / h | 140 m³ / h | ||
So, from three calculated values \u200b\u200bwe accept the maximum - 249 m³ / hour, as it fully meets all the conditions. Round it up to 250 m³ / hour, and give it a summary performance of exhaust ventilation in the kitchen, in the bathroom and in the bathroom.
Kitchen should give more - she has a more significant area and ventilation rates in this room tougher. In our case, it can be removed 150 m³ / hour. This can be a total ventilation + kitchen, but only if the extractor works with the output of the air outward, and not according to the projection principle.
The remaining 100 m³ / hour can be evenly distributed between the bathroom and the toilet (if it is planned to install individual for each room of axial fans). Or, in the case when these rooms are combined with one exhaust system, you can set a common channel or radial fan of the corresponding performance. Obviously, such volumes of exhaust ventilation are quite enough in comparison with minimal norms, even with a good margin.
So, all conditions are fully fulfilled, and the required ventilation unit performance is also defined.
Other fan selection criteria for bathroom and toilet
It is very important to know what else to pay attention to when choosing an exhaust fan for the bathroom rooms, in addition to its performance. These criteria include the following technical and operational parameters:
- The level of noise created during operation. The functioning of any ventilating device is accompanied by mechanical and aerodynamic noise. These sound oscillations apply to the air, through the air ducts and surfaces of the walls within which they are laid.
Mechanical noise occurs from wheel vibration with blades, electric motor and casing, in which the entire design is installed.
The aerodynamic noise appears as a consequence of the vortex formation inside the casing in the blade wheel, at the inlet and outlet of the air, when it is moved through the air ducts, as well as during the case ripples.
Increased vibration and noise of the ventilation plant can adversely affect the well-being of the residents of the apartment or at home.
Therefore, for fans installed in residential premises, there are certain limitations of the noise pressure created, and this parameter itself is defined in the product passport (often - even in a certain range of removal from the device).
If the fan is acquired with the possibility of adjusting the engine speed and, accordingly, performance, then preference should be preferred, which can cope with the required setting of the required air volume not at its maximum, but about 0.5 ÷ 0.7 from its incorrect features. So the technique will last longer, and the noise level will significantly decrease - high turns most often are the main cause of noise.
It should be noted that manufacturers install special silencers of one or another design for many fans - be sure to consider this when choosing.
Another important point of noise reduction is to install a fan with rectilinear areas to stabilize air flow that reduces turbulent phenomena. For a channel or radial fan, such sites are desirable to leave on both sides (for axial, it is clear, it is not possible to comply with the fullest). The length of each such plot should be at least 1.5 external diameters of the impeller (turbine).
- Fan functionality. Exhaust ventilation systems can be automatic or standard.
Axial conventional fans can work from manual power on, or they are embedded in general System Lighting the room, that is, when the light is turned on, the exhaust fan is turned on.
The last option is more convenient and economical, but there is some kind of prudency, so that the entire ventilation system of the house does not suffer when the device is off. The outflow of air from the residential zone in the minimum required amount should be ensured constantly.
The automatic design of the device assumes the presence of an electronic unit with a timer, which is set to power on, operating modes and a fan shutdown.
- Safety device. Since the fan runs from electricity, the instruments protected from moisture are selected for the bathrooms, on the packaging of which the corresponding label should be.
Choosing a fan, it is worth checking the availability of a quality certificate on the product. It is necessary to purchase such devices necessarily in specialized stores, preferably - models famous manufacturers, whose mark itself gives a certain warranty on products. Feel free to demand the simplicity of the necessary marks for sale in the passport - to ensure further warranty and service.

Independent installation of ventilation
Install the fan in the bathroom or toilet apartment is quite simple, since the ventilation system in multi-storey houses is already arranged, and the device will only increase the exhaust air hood along with unpleasant odors and humidity.
It is more difficult to install the ventilation system in a private house. But it is also quite possible to do it. Of course, it is best to install all the elements of the system at the construction stage, but it is often necessary to carry out these installation work and in the ready-made structure.
Elements of the ventilation system
If the view of the ventilation system is defined, then you need to prepare all the elements necessary for it in advance dimensions.
- The fan is the main component of the system and can be built into the wall or ceiling, as well as the duct box. In the air duct, the device is usually embedded in the case of the planned installation of a complex ventilation system. For example, if the bathroom and toilet are separated (or even spaced) among themselves, then in each of the rooms it will be possible to arrange its own ventilating hole, from which the box or pipes are discharged, connected to a single air duct, equipped with a channel or radial roof fan.
- Duct boxes can be made of plastic or metal, have a round or rectangular cross section. Each of them has its advantages, for example, a rectangular option is more convenient to mount to the ceiling or wall, it can be perfectly located above the suspension or stretch ceiling. The round cross section provides a more efficient removal of air, since it does not have inner corners, delaying its smooth movement or delaying.
Air ducts of rectangular section is easier to mount to walls and flow, but round - less "noisy" - Rotary knees are used when using hard boxes. They are installed in complex structures, with a change in the direction of air ducts, with an output through a wall or ceiling and in other cases, according to the assembly plan.
- Connecting clutches are used to conjugate individual duct sections.
- The check valve is set to avoid the air reverse current when the fan is turned off, or, for example, with strong wind on the street.
- Elements for fixing ducts. To do this, you can use homemade or ready-made brackets (clamps), which are usually installed every 500 ÷ 700 mm, depending on the placement location.
- The ventilation grids, installed on the input and outlet of the system, will be required in cases where the channel fan is selected between the two parts of the air duct. One ventilation grille will be needed for mounting it on the outlet of the system, when installing an overhead axial fan.
Installation of the ventilation system
Installation of the ventilation system is carried out in different ways, depending on the selected design, and on whether it is updated or is updated again. Therefore, before starting to install, you should draw up a detailed scheme for which it will be easier to work.
- If it is decided to update the already installed ventilation system, it is best to replace the air duct to a new one. In the case when this fails, it will be necessary to thoroughly clean the old duct from garbage and layers on stacks.
- Before laying the ventilation box, it is necessary to determine the place of installation of the fan in advance. The optimal installation site of the device will be a wall opposite to the doorway. In this case, the ventilation system will work more efficiently due to the natural air intake in the form of a draft.
- The next step in the wall is cut new or, if necessary, expanding to the desired dimensions already existing ventilation window.
- The ventilation air duct is displayed in the arranged hole, then gradually mounted, is paved in accordance with the scheme and is fixed in the attic of the structure, or is carried out through attic overlap And roof.
- If the channel is displayed on the street through the outer wall, it is recommended in the vent hole from the side of the street to hind the pipe that is raised vertically at least 500 ÷ 1000 mm. If you install only a protective grille on the through hole, the room will not have time to heat up when the heating system is running - all heat to the draft will quickly go through ventilation.
- The ventilation tube derived through the roof of the building requires a device of reliable waterproofing. For this purpose, special waterproofing cuffs can be used, which are put on the pipe and are fixed on the roof.
- Another option to install the system can be the installation of a fan into the ceiling and connecting it to a flexible ventilation duct (corrugation), which is connected to the outlet, a closed protective grid, installed under the roof sofit. This module is possible as in the complex with suspended ceilingSo without it, as the box can well pass in the attic.
- In case of installation of a complex ventilation system, when the bathrooms are separated, and the ventilation must be connected to one general air duct, you can do the same as shown in this scheme. In the overall ventilation channel, inserts are installed with nozzles that will go into rooms through the suspended ceiling, and the air duct itself can be revealed to the street through the wall. In this case, two fans can be installed, one for each room or one, channel or installed on the side of the street and closed with a special casing.
- After holding and fixing the air ducts, it is necessary to accurately install the axial overhead fan itself, which is inserted into the box and secure on the wall convenient in each particular case and, of course, reliable way. It is necessary to take into account the presence of vibratory loads, so that the fastening elements do not break out over time.
- Before finally fasten the axial fan in the window, you need to connect the device to the power supply. The wire connecting the fan with the switch is recommended to enter into a special plastic cable channel, fixed on a wall that can be placed along the ceiling or hide over the suspension design.
The fan is connected to the power supply through the connecting terminals, which must be hidden under a special cover or casing, so that the active impact on them of high humidity is expelled.
Depending on the design, the terminal block is located differently, but the connection scheme is always attached to the fan, which will help navigate in this matter.
If it is decided to join a fan with a light switch, then this switching should be done in about the way as shown in this scheme:
Connection in this method is carried out in a distribution box specifically installed for this, where the "zero" and "phase" wires of the fan and lighting are connected using the terminals. A "phase" is interrupted on the switch, and there is already a connection to both instruments.
By the way, if it is good to think about it, then such a scheme is very irrational. We simulate the situation - the man accepted the bath or souls, lasted, dressed, left the bathroom and redeemed the light. During this time, an excess of moisture is unlikely to be completely elongated with a fan, and "pairs of post" remains in the room. A similar situation and use of the restroom. It will be wiser with such a connection to provide a temporary delay, at least 5 ÷ 10 minutes by installing a simple time relay in the fan circuit.
By the way, if you wish, you can find electronic timer control devices and ventilation devices developed precisely for these purposes.
- When installing a channel fan, it is necessary to thoroughly consider it to connect it to the power supply, especially if the ventilation channel is planned to be carried out through an attic room. Through the ceiling, it will be necessary to pave an electrical cable, and it itself is in all its length, all its possible connections, as well as the passage through the overlap, should be securely extinguished.
- If the system is mounted under the ceiling of the premises, then the air duct together with the fan can be hidden over the suspended ceiling. In this case, the vent hole can be organized in the ceiling, where the air duct is displayed and fixed, and then cover it with a decorative-function lattice window.

Checking the installed system
After completing the installation of the ventilation system, it is necessary to check it. In order to carry out such control, no tools will not need - it is enough to bring the paper sheet of the paper or a lit candle to the lattice. If the paper sheet attracted to the lattice, and the flame of the candle will lean towards it, then we can say that the fan works quite efficiently.
If you need to increase the craving, then you can stimulate a small artificial draft. To do this, a narrow sliding window is cut into the bottom of the bathroom door or a series of holes is dried. These cuts are then closed on both sides of a specially designed ventilation grille. It, depending on the design and type of holes done, is inserted into the through opening, it can be glued to the door or fastened with self-draws.
Hello, dear friends. Today we will talk about very important, although sometimes, and not staggering, things. Planning the design or repair of bathrooms, you should always consider the ventilation system. The problem of air exchange is a serious and very responsible stage of repair. In low-speed and regulations regarding ventilation, the standard of air exchange standards in rooms in which there is plenty of water vapor is prescribed by separate items.
It should be remembered that the ventilation is not only a matter of comfort and convenience. First of all, it is very important for health. Moreover, in the premises, of which water pairs are not displayed in due quantities, fungus or mold will always start.
If the malicious flora has already begun to develop under a tile or on the side of the shower cabin (and notice the fungus is not so simple, about a year it develops very conspiratically), then the absence of a ventilation system helps him grow and spread in the form of an air dispute.
Construction directories of all countries and peoples contain a number of standards that need to be strictly implemented to ventilate wet rooms.
Ventilation systems should enrich the bathroom with 25 cubic meters of air every hour. For a combined bathroom (bathroom + toilet), ventilation should bring 50 cubic meters of air. Moreover, these norms are minimal.
Specialists in ventilated systems are advised to produce bathroom ventilation with 75 cubic meter air exchange per hour and 150 cubic meters for combined bathrooms.
For bathrooms there are two types of ventilations: natural and forced. The method of using each of them depends on the specifics of the exchange of air. Natural ventilation provides an exchange of air with the absorption of it from the external environment, which can only take place due to the pressure drop.
Air masses can get inside through the window, door, ventilator, etc. It is necessary to admit that, in the case of a separate toilet room, natural ventilation is acceptable. However, for the bathrooms of the combined type, it often turns out to be ineffective.
Types of ventilation systems
Professionals advise using two varieties of ventilation systems:
- channel ventilation system;
- burnt ventilation;
The difference between these systems is obvious on the basis of their names - in the first design there is a ventilation channel, in the second - air flow is provided without that.
When working with bathrooms or bathrooms, it is advisable to eliminate the creation of individual channels. In the wall, it is customary to create an opening and remove the exhaust air into the overall ventilation branch of the building. Such a procedure is not only more convenient and less costly, but also more rational. Of course, this is applicable to multi-storey urban buildings. But, if we are talking about a private house, you need to design ventilation at the stages of the construction, during the construction of the walls.
The air intake in the bathroom and the toilet is implemented, as a rule, on one channel - in the bathroom, after which an additional intermediate opening is created in the wall between the bathroom and the toilet for the transition of the exhaust air.
The exhaust fan designed to use ventilation in the bath through the toilet may have the most different appearance and size. But the most important is the power of the fan. It is obliged to match the current in the wiring.
Fans possess the following design differences:
- the axial model moves the air parallel to the axis of the instrument. This is carried out thanks to special vanes. These systems are designed exclusively for soft-clean structures;
- diametral models with rather low performance have special wheels of drum types in their design;
- a centrifugal type device having a spiral case guarantees extremely high performance, but during operation the system creates quite strong noise;
- combined, centrifugal-axial device more silently works with the same efficiency as a simple centrifugal system.
Norms and requirements
We study the slope and other regulations In order to understand how much new air should come to a bathroom or toilet during ventilation.
According to the regulatory documentation, the bathrooms with dimensions of about 10 square meters and more should once receive new airflows at the same time.
Get out of the bathroom and the bathroom should have more than 30 cubes every hour. If the bathroom room is large, then the calculation goes to the area of \u200b\u200ba small living room and is multiplied by 1.5 (due to high humidity). These are the norms of ventilation, these numbers are minimal requirements.
Criterias of choice
It should be understood that, in cases where natural ventilation in the toilets via bathrooms cannot be implemented (it is impossible to guarantee the influx of even 20 cubes of fresh air per hour) means it is necessary to install forced ventilation systems.
There are three types of ventilation:
- exhaust system;
- supply system;
- mixed.
As for exhaust systems, we have already discussed them - the air comes from the outside, and the spent masses are displayed in the ventilation channels.
The principle of supply ventilation other - outside the bathroom or toilet, air masses are injected, after which they are displaced into the channels. This is the most optimal and rational system for apartments.
When ventilating the bathroom in a private house it is best to use mixed systems. They combine the exhaust and supply system. Air due to mixed technologies is removed and renewed with the greatest efficiency.
In order to hide the designs use decorative lattices. They may not only be removed from the field of view technical details of ventilation, but also make the interior of the bathroom more stylish.
Household ventilation systems are:
- channel;
- radial.
Both types are intended to install on the outputs of ventilation channels. The channel fan, as a rule, has a rather mediocre design, because it is hidden in the channel itself. However, the radial fan is taken to complement the attractive body, these systems not only carry out an effective air exchange, but also fit into your interior design perfectly.
Diagnostics of the current system when presented
Before you begin to upgrade the ventilation system or clean its filters, it is necessary to carry out a scheduled diagnosis. The state of the ventilation device installed on the principle of "in the bath through the toilet" should be studied thoroughly. Do not be lazy to remove the lattices and clean the inputs and outputs of the channels from dust.
First you need and. To do this, the paper sheet must be placed before the ventilation hole. If the paper sheet is strongly attracted to the ventilation niches, it means that the thrust is present. In case the leaf of the immovable is the obvious lack of ventilation traction in the system.
It must be remembered that the system of the system is such that the pressure drop is carried out at the expense of the temperature difference, so in a hot summer day of traction several times weaker than in winter or autumn.
However, even if the thrust is present, and the exchange of air masses occurs perfectly, it is necessary to understand that this does not guarantee 100% the complete operation of the ventilation systems.
It is necessary to check the status of the channel as much as possible to check the status of the channel. Channels are cluttered with different objects, web, dust or fragments of concrete and brick after global repairs. After the system is clean, there are no other obstacles to the air, and the ventilation devices themselves are clean, you can begin to upgrade and improve the system itself.
Checking with a sheet of paper must be carried out twice: the first time with the closed doors, the second time - with the open.
Check if presence open door It is advisable to spend twice - with open air sources (open the window or entrance door) And with completely closed.
If, after sealing, the thrust decreased almost to zero, then it is necessary to think about additional fans or compact devices for airing.
Specialized lattices are installed in the doors of the bathrooms and toilets - the air enters them inside even with fully closed doors.
Montage with your own hands
When there is no ventilation system in the bathroom or toilet, then it's time to start designing it yourself and mount it. These works are performed quite simple.
In apartment buildings, the systems are designed so that ventilation moves are located on the reverse side of the baths and bathrooms. The whole procedure will be that it is necessary to carefully create a hole and output it into the ventilation channel. In high-rise buildings there must be niches leading to ventilation channels.
Niches themselves can be equipped with radial, axial fans; Devices are connected to power sources, one of the wires are connected either to a separate switch, or on the same that the light chain opens in the bathroom. It is quite convenient, since the fan will be guaranteed to work when the light will light up in the bathroom.
The range of modern systems in the market of ventilation products and services allows you to install a plurality of additional attachments - gyroscopes, temperature sensors, moisture regulators, revolutions, timers. After that, the hole is closed with beautiful decorative lattices.
In cases where the bathroom is not combined when the bathroom contains Ventkanal, and the toilet does not apply the same technology, only twice. The first fan is installed in a niche between the bathroom. and the canal, the second - in the second niche, between the bathroom and the bathroom.
In the case when you need to mount ventilation in the toilet in a private house, you can make not only the exit to Ventskanal, but Ventkanal itself. Specialists advise either to take into account the channels when the walls are built, or competently connect to the exhaust system of the furnace (if there is such).
Let us turn to the practical schemes and projects of ventilation systems.
Design system
For the introduction of fans into wall openings, the most correct is the use of not only decorative lattices, but also filtering systems. If you have to knock out an extra hole between the bathroom and the bathroom (for air wiring), the filter between two rooms is a very rational fragment of the ventilation system. After all, polluted air from the toilet will not be able to penetrate the bathroom.
Imagine the Fan Connection Scheme in the figure to the general wiring:
The installation scheme of the ventilation system consists of the following strategic stages:
- mounting the duct (it is important to pick up proper diameter and length);
- design the optimal exhaust system for bathrooms (taking into account the power of the wiring);
- do it yourself in the toilet (you can and with the help of the wizard) do a neat smooth hole;
- Install ventilation in the toilet or bathroom;
When ventilation systems need to be introduced into toilets and bathrooms of private houses, it is necessary to start with the organization of the connection of Ventkanal to the general chimney; Or create ventilation channel.
When designing a new channel, it is necessary to carefully calculate all stages of ventilation laying through the bathroom.
We advise you not to use metal cobes to create a ventilation channel of a private house. Not only metal constructions Oxisions and require dismantling and replacement every 5 years. If the ventilation channel for exhaust air will be applied with direct yield into the chimney, then due to carbon dioxide, the metal surface of the box will become even more corrosion.
The most rational is the installation of plastic boxes. No wonder they almost completely crowded metal from the market.
Try to avoid corrugated pipes, they are optimal only for short ventilation channels.
Coffee must be installed during all repair work. Moreover, it is advisable to install even before the process is running.
However, even after you have been designed personally, the entire system was convinced that it functions and meets all regulations, ventilation may fail. The problem may be with inaccuracies in the calculation of the sections of the ventilation channels. Also, samia frequent errors Is the wrong installation.
If after you built the ventilation system has passed a lot of time, and after this time the system began to clutch noticeably, it means a lot of garbage, which falls from the roof from the roof, or from the air. If someone from the neighbors did such a major overhaul, which affected the box, then the reason could be in the plugs of the construction garbage located across the air stroke.
- Specialists advise not to postpone the inspection of the ventilation system all the time for later, it is extremely desirable to maintain fans a little earlier than it starts fail.
- As a rule, if the inspection is constantly postponed, then flakes of dust, web or poplar fluff fall into the fan axis, a long time block the rotor and a stator motor, after which the fan simply fails.
- Of course, the purchase of a new motor or fan is entirely a simple solution to such a question, but it will still have to clean the ventilation channel. It is much easier to produce these works on time.
- Independent actions regarding fans provide for cleaning of fan propeller petals, careful cleaning of ventilation grilles and replacing all filters (if any).
- After that, it is necessary to check the air craving, applying a sheet of paper or a flame lighter (we described above, how this procedure is produced). If the fire from the lighter (or matches) is deflected at an angle of 40-50 degrees, then the operation of the fan is considered normal if the flame is not deflected, the ventilation channel is considered scored and further fan operation is load.
- In such cases, it is best to call a specialist, but you can also cope. If various attachments are included in the ventilation system - external interfaces, sensors, thermometers, remote remote controls, it is mandatory to contact a special organization.
- Also, experts pay special attention to the capacity of household wiring and power grid. Fans have two parameters for which they are distinguished by - created pressure and power. These characteristics are associated, since, the greater the power of the motor, the stronger the pressure. It is necessary to know well the condition of your wiring, try to avoid high-power fans.
In the bathroom and the toilet is stronger than in other rooms, condensate is formed, unpleasant odors appear. Therefore, here the arrangement of proper ventilation is extremely necessary. High-quality extractors contributes to the normalization of the microclimate indoors, ensures its compliance with sanitary and hygienic standards and requirements.
Ventilation in the bathroom and the toilet avoids the appearance of dampness and fungus. This contributes to the normal well-being of people living in the house. Finish, plumbing, furniture, which is located in such premises, will serve much longer. All work can be made independently. To do this, you need to familiarize yourself with the existing ventilation rules in the toilet and the bathroom.
Requirements for ventilation
Proper ventilation in the bathroom and the toilet is one of the important factors that make it possible to fully exploit the room. It is as important as heating, lighting and water supply. The quality of equipped ventilation depends on the correspondence of the oxygen medium within the home by existing requirements.
Bathroom and toilet are closed, poorly ventilated rooms. There is an increased probability of breeding pathogenic bacteria and fungi. Snip sets air exchange rates. Its intensity per hour should be 25 m³ for the bathroom. Air flow per hour for a combined type bath should be 50 m³.
To check the drawing operation, you need to bring a burning match to the ventilation grid. If the flame is not retracted by the channel, it means that ventilation in the bathroom and the toilet does not function. In multi-storey houses of the old sample, such a picture is observed due to channel clogging. If a similar problem is defined in a new house, it means that the system was designed incorrectly.
The best solution to the problem will be the arrangement of new forced ventilation. Such a system has a lot of advantages over passive hood. It is able to quickly solve the problem of dampness and the appearance of fungus, an unpleasant smell in such premises.
Type of air exchange
Ventilation in the bathroom and toilet, the options for which today are offered by real estate owners, may be natural and artificial. In ordinary multi-storey buildings built in the past century, the first type of systems is applied. From the windows and doors of fresh air in this case enters the room. Then he leaves through the ventilation channels.
The movement of air masses with natural ventilation is achieved due to the indoor indoor difference and on the street. In modern apartments, windows and doors are distinguished by high tightness. It disrupts the natural indoor air cycle. Therefore, purchasing new plastic windows and sealed doors, you should provide for the presence of ventilation devices.
Forced or artificial ventilation assumes the presence of special equipment. It is embedded in the air exchange system. Exists a large number of A variety of fans for forced ventilation. They discharge pressure inside the bathroom and toilet. The air is pulled out. This process leads to admission to these places of oxygen from other rooms.
The arrangement of forced exhaust in the bathroom is able to solve the problem of ineffective natural ventilation. It requires more time and costs when installing. Over time, the efforts have spent fully compensated. All interior items and decoration in such premises are much longer than with the natural type of air exchange. Health people will not threaten various pathogenic microorganisms. Therefore, the forced extract today is preferable.
Types of ventilation
Sanitary and hygienic and building standards argue that forced ventilation in the bathroom and the toilet is preferred. However, it should be noted that there are several more signs that are distinguished by such systems.
For the purpose, the supply, exhaust and mixed ventilation are allocated. In the first case optional equipment Provides fresh air to the room. At the same time, excessive pressure is formed. It causes old air masses to leave the room through the outlet ventilation channels.
The exhaust type of the system involves the presence of a fan directly on the channel mine. In some cases, a combined method is applied. It assumes both types of system arrangement.
Ventilation varies and design. There is a channel and vague-free hood. The second option involves the movement of air masses through the equipped holes in the walls between the rooms. For example, it can be ventilation of the bathroom through the toilet or vice versa. In one of these premises there is an exit to the total house of the exhaust mine. Air from the second room first through the hole in the wall falls into the first room, and after that, mixed masses overlook the canal from the apartment.
However, the channel ventilation is more efficient. It involves losing the exhaust mine directly to premises with high humidity. It provides a full air exchange in the bathroom.
Type of fan
Forced ventilation in the bathroom and the toilet involves applying additional equipment. It may vary by installation and design. Fans provide sufficient air exchange speed for a combined and separate bathroom.
By the installation method, the equipment of the radial and channel type is distinguished. In the first case, the fan is mounted at the mine output. Its housing has aesthetic case. Channel varieties are installed directly in the mine itself.
By type of construction, diametral, axial, centrifugal and centrifugal axial fan are isolated. In the first version, the product has a drum type of impeller. This design has a small indicator of the efficiency. The axial fan is injected by the air flow using the blades. Such equipment is applicable for chamberless ventilation.
The centrifugal fan has a spiral body. This is the most productive, but the most noisy equipment. The highest operational indicators has a centrifugal axial fan. It is compact, produced and has a small level of noise. Today, equipment in which humidity sensors are built, the timer is built. This allows you to ventilate the room as high quality as possible.
Ventilation channel
There are certain requirements, how to do (ventilation in the bathroom and toilet with your own hands should be performed with high accuracy) the correct system. They must be considered before starting work.
Ventilation channel in a private house works simply. It joins special equipment or excreted on the roof. This is a simple job. The creation of the project is required to make even at the stage of preparation for the construction of the construction.
The highest quality ventilation is obtained in houses from natural wood. This is explained by the ability of the material to "breathe". In this case, it will be enough to equip natural ventilation. Building from logs and timber is considered not only beautiful, but also practical.
Owners of apartments in high-rise buildings are required to pay more time and attention to ventilation. All apartments in the stairwell are communicated with the shared shaft, in which the air leaves the house outside. If, for example, a bath and a toilet is one room (no ventilation ventilation), on the standards of SNiP, air exchange is required per hour in an amount of 50 m³. The higher the apartment is in the house, the greater the likelihood of compliance of this indicator of the established level.
Over time, the channels in apartment buildings are clogged. If they are not cleaned for a long time, the air exchange with natural ventilation is hampered. The lower the apartment is in the house, the worse the hood takes place. In this case, the installation of forced ventilation is simply necessary.
Fan power
To understand how to make (ventilation in the bathroom and a forced type toilet - one of possible options In this case) exhaust in the bathroom, you should consider the basic requirements for creating a similar system. In this case, it is assumed to install an electric small fan. This device must be safe. It should not be out of order when a pair or water design elements. Also should be paid to the level of fan noise. He should not annoy the owners of the house.
Special attention is paid to the choice of power equipment. This indicator affects the dimensions of the bathroom and the number of people permanently residing in the house. For calculations, it is necessary to calculate the area of \u200b\u200bthe bathroom and toilet. Next, the result obtained is multiplied by 6, if the number of users does not exceed 3 people. If in the family 4 and more people, it means, the size of the bathroom is multiplied by 8. The result obtained and will be the optimal power of the fan.
Fan installation rules
Ventilation in the bathroom and toilet, the installation of which is performed with your own hands, requires right mounting All system elements. There are several requirements for the location of the equipment in the room.
The ventilation channel must be at maximum height, preferably under the ceiling. It should also be located as far as possible from the source of air inflows in the bathroom. If this requirement is not fulfilled, only part of the room will be ventilated.
For forced ventilation, it is important to establish a fan away from the water source. This will prevent a random hit in it.
If there is no ventilation in the room, and the exhaust channel is in the adjacent room, you will have to provide installation of additional boxes and pipelines. There are hard plastic and mobile corrugated structures.
Methods of installation
Most often, ventilation in the bathroom and the toilet does not require the facilities of additional air ducts. It is enough to install the selected fan to enter the min. In this case, the overall exhaust channel must be immediately behind the bathroom wall or a combined bathroom.
It happens that the mine of the ventilation canal is located behind the wall in the toilet. If it is separated from the bathroom by partition, through it you can make a hole. On both sides of the walls are installed ventilation grilles. This will be enough to create the required air exchange.
If there is an exit to the mine both in the toilet and in the bathroom, you should do separate ventilation for each room.
One of the most effective approaches is to install on the entrance to the lattice mine with grooves to install forced ventilation equipment. In this case, the natural and intensive systems are combined.
Preparation for mounting
At the repair planning stage, a project is created in which ventilation in the bathroom and toilet is thought out. Tips of experienced builders will allow preparation and installation correctly. Planning will hide the wires under the walls of the walls, calculate the required characteristics of the equipment, as well as the location of all elements of the system.
If ventilation is created in a multi-storey apartment house, it should be responsibly referring to the cleaning of the Shakhtya channel. If property owners live on the upper floors, you can perform this work yourself. The roof is the exhaust mine. It needs to be omitted in it. If the owners of the apartment live on the lower floors, without the help of representatives of the Jeep or special services will not do.
In a private house, clean the ventilation channel will be easier. Over time, dirt, web, garbage from the roof, etc., also accumulate here. By purchasing all the necessary elements of the system, you can start the installation.
Installation of fan
Ventilation in the bathroom and toilet with your own hands is mounted simply. First, the equipment forced type of system is supplied electric wire. It is selected according to the selected fan power. Also, such conductors must have a high class of isolation.
The fan is installed in the place prepared for it. It is attached with the help of self-tapping screws. The grid is also installed using a special fastening material. This will allow you to unscrew the lattice over time and clean it from pollution.
If an additional ventilation channel indoors is placed, you can sew pipes under the ceiling of plasterboard. So the appearance of the room will be aesthetic.
Having considered that it represents ventilation in the bathroom and the toilet, as well as the rules for its installation, each owner of the apartment or private house will be able to create a full-fledged system in the bathroom independently.
For each bathroom characteristic is an elevated level of humidity. In order to prevent such a phenomenon as the formation of mold or fungus, it is worth checking the self-functioning of the ventilation system or install additional equipment. Very often, many people arise how to make ventilation in the toilet with their own hands.
Check ventilation operation Simple: paper sheet applied to ventilation hole, should not fall.
In order for the mold on the surfaces does not occur, there are several options to combat it:
- insulate all surfaces - this method will prevent the formation of condensate;
- highly effective method is a device forced ventilation.
Cleaning natural ventilation
To clean the ventilation from dust, garbage Use the rash with a long flexible handle.
If a natural ventilation system is bad in the toilet, it is necessary to clean the channels. To do this, it is from the channel to eliminate all the accumulated dust and web. To carry out such a procedure, it is worth using a rash with a long flexible handle.
Specialists who are engaged in cleaning ventilation channels can use a more dangerous purification option, which uses a gas can be used with flammable liquid. This method involves burning dust. To conduct such a procedure independently, not having experience, is strictly prohibited, it is better to entrust all specialists.

Forced ventilation
In order for high-quality air exchange in the toilet, it is worth doing ventilation that will work automatically. It is very important for the air with heavy smells and evaporation to penetrate the living quarters. Forced need to be equipped with its own exhaust channel. Before the owner will be presented to the selection of ventilation systems of the ceiling and wall species.
Diagram of the device of general ventilation in the bathroom and toilet.
For the premises of the toilet it is worth picking up a suppressive ventilation system as forced ventilation. Such a system will regularly circulate the air indoors. In addition, it does not imply the cutting of additional ventkalanal, which subsequently can break the strength and reliability of the wall.
Ventilation in the toilet, with your own hands constructed, the case is quite simple, the main thing is to understand all the nuances. The need to make ventilation often arise at the time when natural ventilation does not fully fulfill its basic functions.
This problem is especially manifested in the summer, this is due to the fact that the temperature outside and indoors is almost the same, and the Bernoulli effect does not work. Also, the deterioration in the work of natural ventilation is due to the fact that plastic windows are installed in apartments and homes, which are hermetically closed the premises and prevent fresh air penetration. Also, the doors that are tightly closed, prevent air penetration into the room of the toilet. This problem is especially traced on the upper floors of high-rise buildings, where the temperature in the summer is significantly higher than in the room. It is less noticeable to this problem on the lower floors, where the temperature difference remains even at minimum indicators.
As an option, an automatic exhaust system can be installed, in which case the air will be forcibly output from the room outward. But it is worth considering, due to the lack of air in the premises of the maximum efficiency of such a system, it will not be achieved.
The best option is to make ventilation in the toilet of the supply and exhaust type.

What may be required in the process of work
Fan connection diagram to light switch.
In order to make ventilation in the toilet with your own hands, it is worth purchasing all the necessary tools and materials. Everything you need can be bought in a special department of the construction store. It is worth buying everything at once, after reaching the plan to be mounted forced system Ventilation.
Examples of materials to create forced ventilation:
- corners are tin - today they are represented by various forms;
- plastic box;
- air ducts are flexible, which are made in the form of flexible aluminum pipe;
- plastic pipes corrugated;
- plastic ducts flexible;
- fans;
- recoverators.
In order to carry out installation work on installing the ventilation system, it is worth preparing the necessary inventory:
- roulette and labeling pencil;
- hacksaw and scissors;
- construction knife;
- hammer to clog dowels;
- drill and screwdriver;
- screwdriver with different nozzles;
- fastenings - dowels, screws, self-tapping screws.
In winter, it is very important to equip the ventilation system with supply valves.
Fan power circuit from light switch with timer.
This element is a conventional hole in the wall with a nozzle with one or two sash. The location of the sash can be performed manually or an automated way. For maximum comfort, such a hole is located behind the convector or heating radiator.
This location contributes to an increase in thrust and simultaneous heating of air. This will allow you to use the ventilation system without additional fans. One valve is enough to ensure normal air exchange in one room. In order to protect the room from the penetration of garbage, it is worth installing the grille.

Application of recuperators in the ventilation system
For the premises of the toilet, it will still be the best option to equip a special fan system, which will significantly improve the performance of the entire system. This is especially necessary for the summer period. Modern technologies go ahead, and one of the modern elements that the ventilation system can be equipped is a recuperator. This device will circulate air regardless of weather conditions on the street. In order to establish the supply and ventilation system, it is necessary:
The diagram of the supply and exhaust installation with heat recuperator and air filtration.
- 4 holes that are connected in pairs with special components "Street - Room", "Room - Street";
