Ventilation is an important factor that should not be neglected during the arrangement of the bathroom. Many mistakenly believe that it is needed only to remove unpleasant odors. Therefore, it often happens that the ventilation holes are close in repairs, and with unpleasant flavors fight with air fresheners.
In fact, the ventilation functions are much wider. It should provide normal air circulation in the room, maintaining a certain level of humidity. This prevents the appearance of condensate, mold, fungus and insects in the bathroom.
Often people refuse fan in the bathroom because it produces a lot of noise. Just do not everyone know about the existence of low noise and silent models that do not disturb the calm of households. We will tell about these useful and convenient devices in today's article.
Device
Our article we will talk about fans equipped with a check valve. It is a small and very simple mechanism that prevents air penetration from the ventilation channel back to the room. Check valves are usually produced from plastic or stainless metal. They consist of three main elements - frames, two flaps and pins, which are attached to the sash.
In addition to the check valve, the following elements are present in the design of the silent fan: air intake grille, aerodynamic impeller, vibrational inserts and engine.
Principle of operation
The principle of the reverse valve operation, regardless of where it is installed - in the ventilation channel or in the sewer pipe - will be the same. It is designed in such a way that the movement of air (or water) can occur only in one direction. When trying to move in the opposite direction, the air will be stumbled into a barrier of tightly closed flaps.

The flaps are driven by air movement, which, in turn, is carried out when the fan is turned on. Thus, the air is drawn until the fan turns off. After turning off the sash slam, blocking the air the return path.
Due to what the fan is Beshum?
A silent fan for the bathroom becomes, thanks to some design features, we will briefly tell about.
- First, in the engine device there are special vibration-insulating elements that absorb vibrations that are the main source of noise.
- Secondly, manufacturers carefully think over the appearance of the fan. The air intake grille has a special, streamlined form. In addition, the choice of lattice material also plays an important role - air resistance depends on it.
- Thirdly, the silentness of work is achieved at the expense of another model of bearings. In addition to noise absorbing properties, they have a high degree of reliability and do not require additional care (in particular, with lubricant processing).
Types
Manufacturers of household ventilation equipment offer three varieties of fans that are suitable for installation in the bathroom:
- radial - large-sized models with a spiral array, which today prefer to install mainly in industrial premises;
- axial - represent familiar to each devices that lead air into motion with the help of rotating blades; Such fans can provide an influx and air exhaust;
- channels are the most quiet of all presented varieties, as they are mounted not on the wall, but directly into the ventilation channel; Thus, the noise of the running fan simply does not reach us, since the device is in the distance.
Views on the principle of action
Different types of check valves can be used in silent fans. Depending on the principle of operation distinguish three types of these devices:
- The check valve of the controlled type - runs from electricity or is powered by manually;
- The feed valve of the self-closing type is activated by tensioning or weakening the spring;
- The feed valve of the passive type - it works under the influence of gravity, it opens only towards the air flow.

Tips for choosing
- When choosing a fan for a bathroom, you need to take into account several important parameters, including power, darling of air exchange and noise level. Silent call devices whose power is within up to 26 dB.
- The multiplicity of the air exchange fan is determined by the area of the room. Read more about how the necessary air exchange is calculated in our article "Ventilation in a wooden house. Features of ventilation in the bathroom. "
- For use in rooms with elevated moisture levels (to which the toilet and the bathroom include) you need to choose waterproof models of fans.
- Also pay attention to the presence of additional functions. So, very convenient are fans equipped with an automatic switchboard timer, a motion sensor (presence) and humidity sensor.

Installation
Independent installation of the fan - the task is completely done, even for those who have a minimal experience of repair work. It is only necessary to read the instructions carefully, stocking the necessary tools and the share of patience.
The easiest of the usual axial type fans are installed - it is precisely that used in the bathrooms most often. They are mounted on top of the ventilation hole with a set of fasteners. In this case, the cross section of the air intake lattice must correspond to the size of the ventilation hole.
To connect the fan to the network, you need to bring the cable from the nearest junction box to it (if the fan in this room is installed for the first time). Do not forget that the wiring needs to be completely secured from the exposure to moisture - the wires can be paved in the shoes, hide into special channels, hide under mounted ceiling or a false-wall from drywall.
In the next video of YouTube, you can see how to independently mount a silent fan in the bathroom.
If the bathroom is equipped with a window, you can try to make a silent fan yourself. The homemade fan is attached to the window. He can work on blowing and blowing away. When working, such a fan practically does not make out sounds.
