Choose a fan in the bathroom

Each of us probably noticed more than once that after visiting the bathroom the mirror becomes foggy. For many, this situation is normal, but in fact it is a big problem. Due to impaired ventilation, condensation on walls and other surfaces will promote the development of mold and fungus. Installing a fan in the bathroom, you can solve such a problem.

Today there is a huge choice of fans. This can be as ordinary, having a check valve, not allowing return air, and complex models with timers and humidity sensors. Which fan in the bathroom to choose depends on your personal preferences. The most optimal option for a standard bathroom will be a wall mounted axial fan with a capacity of not more than 150 m ³ / h. If the area of the room is more than 15 m ² , a more powerful device will be required. In addition, the fan in the bathroom must necessarily be waterproof, that is, designed to work in rooms with high humidity. Well, if the fan has a special marking "IP45", indicating the presence of electrical protection.

Most often, exhaust fans are installed where there is an outlet to the ventilation duct. In place of installation and view all fans are divided into axial (ceiling and wall) and centrifugal (ceiling and wall). As already noted, an axial fan model is usually installed in the bathrooms. According to its design, this wheel consists of blades attached to the bushing at a certain angle. Rotating, the blades grasp the air and direct it from the room. These fan models have compact dimensions, high efficiency, and they are easy to adjust.

It is much more difficult to choose a fan in the bathroom if the ventilation duct is clogged, or it is long, or there is a one-pipe ventilation system. In this case, the axial wall fan is not used because of low power and centrifugal fans need to be mounted. They are easy to maintain, quietly operate and have a high efficiency. Centrifugal fans for the bathroom can create a strong air pressure. In the spiral housing there is a shovel wheel. When it rotates, air, getting between the blades, is compressed and directed radially from the center. Further, it enters the spiral housing, and then into the discharge hole. Blades can be bent back (then saves up to 20% of electricity), or forward (then the diameter of the impeller and its rotation speed is less, and the noise level is lower). Centrifugal fan in the bathroom is made of plastic, and therefore weighs a little. It is easy enough to install it.

When assembling household fans, it is important to remember that they should be placed as far as possible and higher from local points where airflow is possible. Do not install fans above objects that can warm air above 45 ° C, for example, fireplaces. A ventilator operating at 220V must not be located in the reach of a bathing person. If an open fire is used in the room, it is important to ensure air access to prevent the hood from escaping.
