How to choose a bathroom fan. Silent bathroom fan with check valve: selection and installation Powerful exhaust fan in the bathroom
As a rule, windows are not provided in bathrooms, and the ventilation system remains the only way of air exchange. It can be natural or forced. In the second case, a bathroom fan is installed in the ventilation duct.
The role of ventilation in a person's daily life can hardly be overestimated, it is it that provides a healthy microclimate in the room. If we talk about the bathroom, then here, indoors, in conditions of high humidity, the lack of air exchange leads to delamination of furniture, swelling of doors, corrosion of even painted metal, the formation of mold, fungus and the reproduction of insects.
Fan in the bathroom: a luxury or a necessity.
As you know, in any standard project At home, natural ventilation is necessarily provided in the bathroom, kitchen and toilet. It includes ventilation ducts, at the entrances of which there are decorative grilles. The movement of air in the system is carried out due to the difference in atmospheric pressure outside and inside the room. The question is whether it works fully, if at all, preserved after repair.
The effectiveness of natural ventilation depends on many factors.
Air temperature. For example, in summer, due to high temperatures, air exchange is minimal.
Air supply to the house. When in construction were used mainly wooden windows with many slots, this issue was not relevant. But today, with the advent plastic windows, air practically does not penetrate into the room and this significantly reduces the efficiency of the system.
Infestation. Not many monitor the cleanliness of ventilation. Over the years, dirt, dust, cobwebs, insects accumulate in it, and this, in turn, prevents the movement of air masses.
The bathroom is a closed room with high humidity, where the air exchange must be especially good. And the only way to make it effective, regardless of external factors- install a fan. Forced ventilation in the bathroom will provide the necessary amount of fresh air regardless of weather conditions and will allow, if necessary, to carry out mandatory ventilation. But keep in mind that household fans for bathrooms, after installation, close the vent channel and completely prevent natural air exchange.
Solving the problem of air exchange in this way has a number of other disadvantages.
Any device operates with a certain level of noise, which can cause discomfort. A silent bathroom fan would be a good solution, but silence will cost a little more.
The performance of a domestic fan is usually higher than the norm. This means that the operation of the device must be controlled. Especially in the cold season, when continuous ventilation will certainly entail extra heat costs.
Additional, albeit small, energy costs.
Forced ventilation in the bathroom and toilet is a quick and easy way to deal with unpleasant odors, excess moisture and its consequences.
A wide variety of models are presented on the construction market. exhaust systems, but before making a choice of a bathroom fan, you need to decide on some technical and functional parameters of these devices.
How to choose a fan
When choosing a fan, it is necessary to take into account a number of technical characteristics: performance, safety, noise level. These indicators, without fail, must be indicated in the device passport.
An important point: When the fan is turned off, it closes almost the entire opening of the ventilation channel with its housing, and this is bad! Thus, your bathroom is practically not ventilated. The way out is to install an additional or double ventilation grille.
Double grids - the best choice for the bathroom and kitchen
Fan performance is the volume of air that will be moved in a certain period of time. For any room, this indicator is calculated by a simple formula: the volume of the room is multiplied by the air exchange rate, this indicator is set by building codes. For bathrooms used by 1-3 people - 6, more than 3 people - 8. The resulting figure indicates at what fan performance all the air in the room will be replaced with fresh air within an hour. The performance of household fans for toilets and bathrooms is usually 90-100 m3/h.
Noise level. Fan operation is always accompanied by mechanical and aerodynamic noise, which should not exceed 35-40 dB. If the inner surface of the duct is lined with soundproofing material or a silencer is installed in the ventilation system, the figure can be reduced. You can also purchase a silent fan for the bathroom, which, however, is a little more expensive.
Silent bathroom fans
Security. Like any other electrical appliance, the fan is prone to short circuits, especially in the bathroom, where the level of moisture in the air is quite high, so it is better to opt for devices with a high level of splash protection.
Forced ventilation in the toilet, if it is not combined with a bathroom, is a purely aesthetic issue. For small room the fan with the lowest performance will suffice. A non-return valve will not be superfluous for channel system ventilation. A high noise level this case some consider it not at all superfluous, although if desired, you can install a silent energy-saving fan for the bathroom.
Additional functions.
A modern bathroom exhaust fan, in addition to the main mechanism, is often equipped with additional options that turn it into a convenient multifunctional device.
Power control is important in order to save energy. Can be manual or automatic.
Humidity sensor. The fan turns on automatically when the humidity level in the room is high. It is worth considering that the humidity sensor is only an additional option, it should not be the only way to turn the fan on and off.
Motion Sensor. An interesting, but not always necessary function in domestic conditions. The device turns on automatically, the set time works.
The timer is a very useful solution. After the set time has elapsed, the bathroom exhaust fan switches off automatically.
The "constant ventilation" mode means that the fan operates at minimum speed, and when humidity rises, it automatically increases performance. This energy saving mode is often used to dry clothes in the bathroom.
A check valve for ventilation is recommended to be installed in duct-type ventilation, as well as for exhaust openings that go directly out of the room. The damper prevents the intake of air from the street or from another room.
Check valve for ventilation
Usually, fans for toilets and bathrooms are installed in place of the ventilation grill, but before proceeding with the installation, make sure that the diameter of the opening of the ventilation duct and the fan housing matches, and the draft is good. They check it with a lit match, if the flame does not deviate to the outlet, there is no draft, the channel needs to be cleaned.
Duct installation
It is better to fix the fan in the ventilation duct using a special polymer adhesive. The front panel is removed and temporarily removed. Glue is applied around the perimeter of the fan cover. The adhesive surfaces are connected for a few seconds. Then they disconnect and give the glue a little “grab”. After a minute, press the fan tightly against the wall. Also, domestic fans can be fixed to the wall with dowels, if there are holes on the panel for them.
Fan installation process
Power connection
Before installing a fan in the bathroom, it is necessary to carry out the wiring, determine the method of turning the device on and off, and designate the installation location for the switches. Only three-core cables are used to connect electrical appliances. Usually the wiring is hidden under the finishing materials. But sometimes, the fan is installed after repair. In this case, the wiring can be hidden under a box or a decorative seam between the tiles. To do this, the seam is carefully cleaned, the wires are laid in it and overwritten again. The box can be easily attached to the wall with polymer glue.
Fan installation process
Connecting the fan to the electrical network in the bathroom can be done in several ways.
to a one-button switch.
The method involves the simultaneous switching on of the fan and lighting. From junction box zero and ground is connected directly. The phase is taken from the same spin, but after the switch. The scheme is simple, but not very convenient, since after the light is turned off, the fan will not remove unpleasant odors.
To a two-way switch.
A more acceptable option for use in the bathroom. One switch key is responsible for lighting the other, respectively, for the exhaust fan for the bathroom. A phase comes to the switch from the junction box, which is switched through two contacts to the lamp and to the fan. Zero and ground come directly from the junction box to the fan and lamp.
To the lamp.
When forced ventilation is done in the bathroom without further renovation, the device can be connected directly to the luminaire. A box is pulled from the lamp to the ventilation duct. The lamp is removed. All wires are fixed on one terminal box. The other end of the wire is connected to the fan contacts. Screw on the protective cover. Before installing a decorative grille, check the operation of the systems.

Ensuring high-quality ventilation in the bathroom is one of the mandatory requirements, since when taking a shower or bath in the room, it forms a large number of steam, which can worsen the microclimate or damage the finish. In addition, sufficient air circulation will normalize the amount of moisture in the room and prevent steam from entering neighboring living rooms through the gaps in the door. Installing a silent bathroom fan would be the best option.
Appearance of a fan with a check valve
Do I need to create forced ventilation in the bathroom or can I get by with natural?
In the projects of most private and multi-storey residential buildings, only a natural exhaust-type air circulation system in the bathrooms was provided. This led to the fact that while taking a shower, steam or bad smell with a certain speed was discharged through a small ventilation hole.
Such a system did not always cope with the circulation of the necessary air volumes and dampness accumulated in the bathroom, creating an ideal microclimate for the development of bacteria or mold growth. The reasons for this were mainly errors in the design of ventilation ducts or their clogging during operation. In the worst case, an unpleasant smell could be reversed due to a change in draft, for example, when opening the door to the room.
When installing forced ventilation, due to the correct selection, all these shortcomings can be avoided. As a pleasant bonus, it will be possible not only to remove polluted air, but also to take fresh air from the ventilation, if an appropriate ventilation system is used, or to provide mixed modes of operation for blowing in and out. That is, if you install an exhaust fan for the bathroom, then the following advantages will appear compared to the natural ventilation method:
- Increased air exchange with the same dimensions of the ventilation ducts.
- Complete absence of condensation on the walls or ceiling thanks to high efficiency steam outlet.
- Improving the dryness of the room.
- Stabilization of the temperature in the bathroom by exchanging air with the interior or exterior.
- No accumulation of dirt in the channels due to powerful air currents.
Why is a check valve needed in a fan design?
When organizing forced ventilation, situations may arise when several fans operate simultaneously, which take or give air. With complex trajectories of its movement, vortices or pressure drops can be created. As a result, the circulation may be disturbed and the unpleasant odor, together with the steam, will go to neighboring rooms. To prevent such situations, a check valve is used, which promptly closes access to the ventilated channel.
Types of check valves for fans
Check valves may differ in material of manufacture, shape, actuation mechanism, installation method, as well as throughput. Usually plastic or metal is used as the material. Plastic is the most beneficial, as it is resistant to moisture, undemanding to maintain and does not significantly increase the cost of the entire device. The metal has increased strength and therefore is resistant to various mechanical stresses. A moisture-resistant check valve installed on a bathroom exhaust fan is identified by the presence of a protective coating.
Helpful advice! Plastic parts housings and structures provide the maximum possible reduction of noise and vibrations, unlike metal ones. Therefore, for the home, it is recommended to choose the first option.
The shape of the valve must follow the contours of the vent to ensure maximum performance of the hood. Standard shapes are: round, square and rectangular.
Ways to control the ventilation valve can be manual or automated. The former have increased reliability and undemanding maintenance. The presence of electricity or its absence will not affect their operation in any way. However, it is not always possible to close access to the ventilated channel in a timely manner, which can lead to negative consequences. Automatic design will provide optimal performance system without outside interference and therefore the most suitable for use in the bathroom.

How to choose the right silent bathroom fan with a check valve?
The exhaust fan in the bathroom should first of all be selected according to the types of execution, since they provide the main performance characteristics and efficiency. They are axial and centrifugal. Axial are a design in which the propeller is located in a plane perpendicular to the ventilation duct. They are usually made of plastic and are easy to install.
Attention! Axial fans are recommended to be installed if there is not only a special seat for their mounting, but also a horizontal section of the air duct at least 3 m in length. This is due to the fact that for such structures it is important to ensure minimal aerodynamic resistance.
Centrifugal are more powerful structures that can be installed even in clogged systems or in the presence of long duct channels. They can also be used if the ventilation system is single-pipe. Structurally, they consist of two parts: a casing and a snail-shaped turbine.
What additional fan features should I pay extra attention to when choosing?
Silent bathroom fan with non-return valve is distinguished by the possible presence of additional options:
- Constant ventilation mode. It differs from the usual standard ventilation in that the propeller is always on, but does not operate at a certain speed, but is able to change, depending on the readings of the humidity sensor in order to dry the room. That is, at the same time, an energy-saving mode and an ideal microclimate in the bathroom are ensured.
- Shutdown timer. Allows you to leave the hood on without worrying that it will have to be turned off after a certain time.
- Hydrostat contributes to indoor maintenance optimal level humidity using automatic control. This feature is especially in demand in bathrooms that are often used or there is increased dampness.
- The motion sensor will provide automatic switch on devices when a person enters a room. That is, it effectively removes possible unpleasant odors. Disconnection is carried out after a certain specified time automatically.
- Splash protection will protect electronic parts from short circuits. The recommended minimum level of protection must be at least IP5.
Helpful information! Buying a suitable bathroom extractor fan is recommended only after the required functionality has been determined. If it lacks an important function, then it will have to be replaced, since today there are no designs that can be configured in accordance with increased requirements.
Overview of some fan manufacturers

We make the final choice of a fan for an extractor hood in the bathroom
The main selection criterion is to ensure sufficient extraction performance, that is, power. This parameter is mainly influenced by the area of the bathroom and the volume of air that stagnates in it. Therefore, initially you need to measure the height, length and width of the room. The volume is calculated by multiplying all the listed values. Then, in accordance with current regulations, the resulting value must be multiplied by the air exchange rate. For a bathroom, this coefficient is from 3 to 8.
Helpful information! It is recommended to take the average value of the multiplicity factor, and round the obtained power value to the nearest whole number.
Other, no less important indicator- the level of electrical safety. In humid environments where water vapor may be present, it is recommended to choose designs in which the connection to the power supply can be made outside the bath or all conductive and contact parts are reliably protected. For safety reasons, it is worth giving preference to low-voltage devices, which are powered by direct current with a value of 12 or 24 V.
Installing a fan with a non-return valve
Installation of a silent fan for the bathroom is recommended in the air duct itself or outside with embedding in a wall or ceiling in a special exhaust airlock. Step by step installation is performed in the following sequence:
Attention! Before installation work it is necessary to de-energize the entire apartment, or locally only the bathroom. When connecting inside the bathroom, it is recommended to take care to provide a sufficient level of electrical protection. If there is any doubt about the quality of the laid wiring, it is recommended to replace it or lay a new one on the wall surface.
- If there are attachment points for self-tapping screws or bolts, then we must screw them in so that, with possible vibrations, the structure is held securely.
- Installing a mosquito net.
- Attaching the front panel.
Conclusion
In order to ensure high-quality ventilation, it is necessary to purchase a noiseless bathroom fan that is suitable for the parameters, which will be with a check valve. This will allow you to get the optimal microclimate in the room and the necessary additional functionality.

Good ventilation is extremely important for bathrooms and toilets. It ensures the cleanliness and freshness of the air in the room. natural ventilation does not always save the day. Sometimes it is advisable to purchase exhaust fans for the bathroom and toilet.
Exhaust hatches installed in old buildings many years ago no longer effectively cope with their functions. In addition, some landlords are renovating, redevelopment of the bathroom and even block ventilation holes to isolate themselves from neighbors. Air purification is also often hindered by clogging of the hood. Over time, all ventilation ducts become clogged with dirt and soot.
Fan on the bathroom wall
However, we should not forget that even a not very old system can cope with the task poorly, since the mechanism of operation of such ventilation is based on the temperature difference in the house and on the street.
In the hot season, the ventilation system works at half strength. Therefore, even in new buildings with relatively good systems air exchange, many residents still think about how to choose an exhaust fan for the bathroom.
Standard bathrooms in ordinary high-rise buildings small in area. Filling the bath hot water, every time we notice that a tiny room literally turns into a steam room, condensation appears on the floor, mirrors and walls. If the ventilation system is not debugged, constant high humidity leads to the fact that the tiled lining loses its attractive appearance, tile joints turn black, mold fungus can settle on the walls.
Darkening of tile joints in the bathroom from dampness
The absence of a natural light opening in the bathroom requires the mandatory equipment of a ventilation hole. Such a system will be the only source of air penetration.
Ventilation is provided for in every project at home, but its work does not always fully ensure proper air exchange. That is why many people, when starting repairs, are wondering how to choose a fan for the bathroom.
What to consider when buying a product
If you don't yet know exactly which fan to put on your tub/toilet, there are a few factors to take into account. The choice of model can be influenced by the number of people living in the apartment, the area of \u200b\u200bthe bathroom. If you use the bathroom mainly in the morning and evening hours, and during the working day the apartment is empty, it makes sense to think about saving energy and install a blower with the functions of turning off the device and adjusting the power.
Today, there are products with a timer for sale.
Bathroom fan with timer
This is a very functional device, since its operation can be set for a strictly defined period of time. For example, an exhaust fan in the bathroom with such a mechanism runs exactly half an hour after you have used the bathroom. At the same time, you set the time that is convenient for you.
Types of bathroom fans
When choosing a particular model, you need to consider its functionality. There are standard and automatic hoods. The standard air exchanger is a traditional axial system equipped with a check valve. It prevents the penetration of exhaust air back into the room. This design is well suited for bathrooms in which the ventilation system is combined with the kitchen. Air is drawn from the bathroom or toilet room, but does not enter the kitchen.
Appearance of a standard axial fan
The principle of operation of such a supercharger is very simple and is directly related to turning off the light. The hood starts working as soon as the light in the bathroom turns on, when it is turned off, the fan itself stops. This is convenient in the operation of the bathroom, but is not very effective at a very high level of humidity in the room. In order for all the moist air to escape, you need to leave ventilation system turned on for a long time.
A more expensive ventilation option is to buy an automatic device with a timer and a humidity sensor. Such a device allows you to turn it on for a certain period of time. For example, an exhaust fan with an automatic shut-off function runs for about 25 minutes after you leave the bathroom. The humidity level sensor sends a signal to the system about exceeding the permissible norm, and the fan starts to function. After a period of time set by you, it turns itself off.
Exhaust system with humidity sensor
To equip the hood with a common system for several apartments, products with a check valve are usually used. This device prevents the flow of air from the ventilation back into the room. The valve protects the space of the apartment from dust, clogging with small particles and poplar fluff.
In addition to the above functions, such a fan reliably protects the bathroom from foreign odors that come from neighboring apartments, for example, from tobacco smoke.
When choosing a particular model, pay attention to the performance of the device, type of construction, noise level and reliability.
Extraction performance parameters
The main indicator of the fan is its performance. The higher it is, the better unpleasant odors are eliminated in the bathroom, and steam comes out. As a rule, standard systems have an output of fifty m3 per hour. Sometimes such an extract is not enough, and apartment owners additionally install a fan.
Fan in the interior of the bathroom
To calculate the performance, use the following formula: the volume of the room must be multiplied by the multiplicity. If the number of people living in the house is 1 or 3, the multiplicity is 6. If more than three people use the bathroom, the multiplicity is 8.
Let us give an example of such calculations. There are 3 people in the family. The length of the bathroom is 3 meters, width - 2 and a half meters, height - 3 m. We calculate the fan performance as follows: 3 * 2.5 * 3 * 6. We get the number 135 m3 / h. Thus, it is recommended to purchase a fan with this capacity.
Reliability and safety of use
One of the main criteria for the quality of the device is its protection against moisture. In the bathroom, drops of water can fall on the fan, so the equipment must have a special marking confirming the protection against moisture in order to avoid a short circuit.
As a rule, fans are marked IPX4. This indicates that the device is safe and has good protection from water.
Fan noise level
The fan during operation should not cause discomfort to the owners of the apartment. It is desirable that the noise emitted by the device does not exceed 40 dB.
Low noise fan
The structure and types of ventilation equipment
Today on sale is a very big choice products for bathrooms and toilets. Before making a choice, you should study the range well and deal with the types of structures.
According to the installation site, for example, wall-mounted models are most popular. They also produce ceiling fans in the bathroom, you can learn how to choose a quality product from our article.
Ceiling ventilation unit
Some devices are mounted behind a false ceiling. Also, according to the configuration, fans are axial, radial, duct, centrifugal and centrifugal-axial.
Axial models are the most common. They are quite powerful and are easy to install. Such equipment provides air circulation up to one hundred cubic meters per hour.
Axial exhaust fan
However, they are advised to be installed when the horizontal section of the ventilation duct is less than three meters.
Centrifugal-axial devices are characterized by even greater power. They are also suitable for installation in the part of the duct that exceeds 3 meters.
Appearance of a centrifugal axial fan
The centrifugal fan works very efficiently. This is a good option for installation in the bathroom, but such models make a lot of noise.
Additional features and uses
Modern manufacturers produce fans with many features for ease of use. So, devices with humidity and motion sensors are very popular among buyers. Such fans turn on automatically in cases where ventilation of the bathroom is required.
Ventilation system with motion sensor
Mounting
Installation does not require special skills. It is only necessary to observe safety precautions, as in working with other electrical appliances.
It is advisable to install the fan immediately during overhaul. Then it will be convenient to bring electricity to the place where the device is attached. The next step is to install the switch. They differ somewhat in structure. One switch is designed to illuminate the ventilation device. The other, consisting of two buttons, is used separately - for light and for ventilation. Sometimes you also need to set up the remote control.
Products with built-in humidity sensors do not require a switch.
After laying the cables and mounting the switch, you can proceed directly to the installation of the fan itself.
Exhaust fan installation
To do this, remove the cover, glue the part of the device that will be attached to the bathroom wall with glue. Then the supercharger should be inserted into the hole in the wall and wait for the glue to dry. After that, you can connect the device to the power supply. At the end, a protective grill and a mosquito net are fixed on the apparatus using self-tapping screws.
Thus, ventilation devices for a bathroom or bathroom can be easily installed by hand. This mechanism in the bathroom is necessary, its operation significantly improves the service life of the bathroom, as it effectively eliminates dampness and excess moisture. Due to the wide range of products, you can choose enough a budget option. It is not necessary to choose the most expensive fan.

Criteria for choosing a fan in the bathroom
The purchase of a fan in the bathroom with a non-return valve should be considered - when choosing, you will have to take into account not only the design and color of the device. No less important specifications. Consider further what parameters you should pay attention to before buying.
The level of moisture resistance of the device
The bathroom or any other sanitary and hygienic room is characterized by high humidity, water splashes and steam generation. For electrical appliances, such an environment is considered aggressive and dangerous.
Only certain types of equipment with a high level of moisture resistance can work in such difficult conditions.
Data on this parameter can be found on the product packaging or in the technical documentation -. The device with the highest performance will be the safest and will not fail even if condensate and moisture accidentally get on the working elements.
If hosts like to sit in the bath for a long time or regularly take very hot showers, fans with good heat resistance should be considered. They will easily withstand high temperatures and will not crack under the influence of vapors.
Optimum fan power
Power is another important characteristic that requires special attention. It shows the level of efficiency of the device and makes it possible to understand how quickly the fan will clear the room of unpleasant odors, dampness and mustiness.
The more powerful the motor, the louder the exhaust fan will make during operation. The owners of large houses will not notice this, but for the owners of small apartments this moment will be very noticeable.
Price and product warranty
It is better to buy devices not in the market, but in specialized stores or at points from official representatives. They will not only tell you how to use the device correctly, but also write out a warranty card for service at a certified service center.
As for color, the choice here is not so rich. If you want to buy not a traditional snow-white product, but a colored one, you will have to limit your choice to just a few models.
The cost will depend on the popularity and promotion of the brand. For a model from European manufacturers, you will have to pay much more.
Domestic units will cost less, but in terms of quality they are almost in no way inferior to foreign modules.
