Silent fan for the bathroom with a check valve : types, device selection and installation

Ventilation - is an important factor, which should not be neglected in the regeneration of the bathroom.Many people mistakenly believe that it is necessary only to remove unpleasant odors.Therefore, it often happens that the ventilation holes are buried in the repair and unpleasant flavors are struggling with air fresheners.

Actually ventilation function is much wider.It should ensure good air circulation in the room, maintaining a certain level of humidity.This prevents condensation in the bathroom room, mold, fungus and insects.

Often, people refuse from the fan in the bathroom because it produces a lot of noise.Just not everyone knows about the existence of low noise and silent models, which do not violate the peace of the household.On these useful and user-friendly devices will be discussed in today's article.

In this article we will focus on the fans equipped with a check valve. It is a small and very simple mechanism, which prevents the penetration of air from the air duct back into the room. Check valves are usually made of plastic or stainless steel.They consist of three main elements - box, two shutters, barriers and pins, which are mounted on the sash.

The principle of operation of the check valve, regardless of where it is installed - in the duct or in the sewer - will be the same. It is designed so that the movement of air (or water) can occur only in one direction.When you try to move in the opposite direction, the air will come up against the barrier of the tightly closed shutters.

Valves are actuated movement of air, which, in turn, is carried out when the fan is switched on.Thus, the air is drawn up until the fan is turned off.After switching off the leaf slam, blocking the way back to the air.

silent fan for the bathroom becomes, thanks to some design features that we briefly describe.

• Firstly, the device engine provides special anti-vibration elements, which absorb vibrations, which are the main source of noise.
• Second, manufacturers carefully think through the outside of the fan shape.Intake Grille has a special, streamlined shape.In addition, the important role played by the choice of the lattice of the material - depends on the resistance of air.
• Third, quiet operation is achieved at the expense of other models bearing.In addition to sound absorption properties, they have a high degree of reliability and does not require additional maintenance (particularly grease processing).

Manufacturers domestic ventilation equipment offer three types of fans are suitable for installation in the bathroom:

• radial - large model with spiral bars, which are now largely prefer to install in industrial environments;
• axial - are familiar to each device, which result in the movement of air by means of rotating blades;these fans can provide intake and extraction of air;
• channel - the most quiet of all presented varieties, as they are not mounted on the wall, but directly in the vent;thus, noise working fan just does not reach us, because the device is in the distance.

The silent fan can be used various types of check valves.Depending on the operating principle of three types of these devices:

• check valve managed type - powered by electricity or actuated manually;
• check valve self-closing - is driven by tension or weakening of the spring;
• passive type check valve - works by gravity, open only towards the air flow.

We offer you an overview of the best models of silent fan for the bathroom, fitted with non-return valve:

• When choosing a fan for the bathroom you need to consider several important parameters, including power, ventilation rate, and noise.Noiseless is a device whose power is in the range up to 26 dB.
• multiplicity of fan air is determined by the area of ​​the room.Learn more about how to calculate the required ventilation can be read in our article "Ventilation in the wooden house.Features of the ventilation in the bathroom. "
• For use in environments with high humidity levels (which include toilet and bathroom) you need to choose a waterproof model fans.
• also pay attention to the presence of additional functions.So, fans are very comfortable, equipped with automatic on timer, motion sensor (presence) and a humidity sensor.

Independent fan installation - a task quite doableeven for those with minimal experience of repair work. It is only necessary to read the instructions carefully, to stock up on necessary tools and share patience.

The easiest way to set the usual overhead fans axial type - these are used in the bathrooms more often.They are mounted on top of the vent using a set of fasteners.The cross section of the intake grille must match the size of the vent hole.

In order to connect the fan to a network, you need to take him away from the nearest cable junction box (if the fan is installed in the room for the first time).Do not forget that the wiring necessary to fully protect against moisture - wires can be routed in Stroebe, hide in special channels to hide under a false ceiling or a false wall of plasterboard.

The following video Youtube channel you can see how to mount their own silent fan in the bathroom.

If the bathroom has a window, you can try to make a silent fan yourself.Homemade fan is attached to the window.Work he can and blowing and blowing.When using a fan is almost no noise.
