Fan for hoods in the bathroom - description, types, tips for choosing a hood

Why is there a fan in the bathroom

Taking care of clean and fresh air in the apartment, we primarily think about living rooms and the kitchen. But starting to deal with the problem of ventilation, we understand that constant ventilation of the bathrooms is equally important.

After all, it is these areas that are the place of high humidity. And excessive humidity can lead not only to corrosion of metal objects, but also to the occurrence of mold and mildew.

Unfortunately, ventilation ducts do not cope with this problem. Especially if it is clogged or has not been cleaned for a long time. The reason for this is the draft, which is too little or none at all, therefore, there is no air circulation.

Important! You can check the cravings in the bathroom yourself. To do this, you need to light a candle or just a match and bring it in the ventilation grill. In the absence of thrust, the flame is kept even, without hesitation or deviations to the sides.

A fan installed in the ventilation opening of the bathroom will solve this problem. He will be able to increase traction, which provides the necessary ventilation and drying of the room.

Types of fans that can be used for hoods in the bathroom

The modern industry produces a wide variety of fans suitable for installation in the bathroom. They can be classified according to several criteria.

Fan location (overhead or duct)

When installing a fan in the bathroom, one of the methods of its location is used. You can fix the device on the wall (such structures are called invoices). This method attracts with the simplicity of installation, however, it requires connecting the mechanism with the opening of the ventilation shaft with a special air duct.

In another method, the fan is mounted inside the ventilation duct, which is why they are called channel.

Mounting location (ceiling, roof, wall)

Overhead fans can be attached to the ceiling, wall or even on the roof of a building, therefore, there are 3 types of devices at the place of attachment: ceiling, wall, rooftop.

Usually, in bathrooms located in apartments of multi-storey buildings, a ceiling system is installed in the channel, and wall devices are used as overhead devices on the wall. Rooftops are used in attics of one- or two-story houses or cottages.

The place of attachment does not affect the quality and result of the work, the specific choice is made taking into account the interior solutions.

Operating principle (vane or centrifugal)

Ventilation structures work in different ways.

V paddle the movement of air masses occurs due to the work of the existing blades or blades. Vane models are divided into 2 groups: axial and radial.

The movement of air due to the internal centrifugal force of the mechanism occurs in centrifugal devices.

Actuation (mechanical or automatic)

The buyer can foresee which option for switching on ventilation is more convenient. Appliance with mechanical activation can be activated by pressing a special button. Or you can combine turning on the device with turning on the light in the bathroom.

Manufacturers also offer devices with automatic inclusion. This became possible due to the use of special sensors. They are tuned to different reactions and independently give a signal to turn on if it becomes too humid or smoky.

Additional features

A hygrometer that can independently measure and control the level of humidity, as well as sensors for automatic start-up, give ventilation systems additional capabilities.

In addition, there are constructions equipped with a timer. It allows you to set the time during which the fan will run. And a sensor that reacts to movement allows the structure to turn on independently when a person enters the bathroom or toilet.

Bathroom fan selection parameters

The variety and variety of fans that can be mounted in the bathroom open up great possibilities for consumers, but make it difficult to choose a particular device. In order not to be mistaken with a purchase, the following indicators should be considered.

Air exchange rate

The main characteristic of the mechanism is the volume of the replaced air. The instruction indicates what the capabilities of the device are. This data needs to be matched to the needs of a particular bathroom. This indicator for each dwelling is calculated individually.

Important! The optimal rate of air changes in the bathroom is 8, and if the bathroom is combined with a toilet - 10.

Calculating the required performance is easy. To do this, the number of air changes (8 or 10) is multiplied by the area of ​​the bathroom (or toilet), and then multiplied by 6 (if the bathroom is used by a family of up to 3 people) or 8 (if there are more than 3 people living).

Advice! Having calculated the required demand using the indicated formula, choose a device whose performance is slightly higher than the result obtained. In this case, the purchased fan for the extractor hood in the bathroom will not be too weak, and also will not cool the room with too much power.

Noises produced

The most suitable device in everyday life is considered to be a device that not only ventilates the room well, but also does it without annoying noise. Therefore, when buying, you need to pay attention to the noise level that occurs during operation. The most comfortable device is considered to be noise from 20 to 25 dB, acceptable - up to 40 dB. If the system is louder, the noise becomes annoying.

Power consumption

Power consumption is an equally important quality characteristic. The lower it is, the cheaper it will be to use the device. But this indicator must be taken into account in combination with the number of air changes. Therefore, it is recommended to pay attention to it, choosing from two of the same performance the one with less power consumption.

The presence or absence of additional functions

In order not to disappoint with your purchase, it will be useful to familiarize yourself with what additional features a particular design is equipped with, and then decide if this feature is important to you. Popular are, for example, fans, in which you can select the speed of rotation of the blades. So it will be possible to increase its efficiency, because a low speed will lead to a decrease in energy consumption.

Important! Fans with a humidity sensor have proven to be more economical to use than devices with motion sensors. These structures will not turn on every time you visit the bathroom, but will start working only after the humidity level rises.

Features of fans with a non-return valve

Some ventilation systems have an element such as a non-return valve. This part can also be installed in the ventilation duct additionally. In this regard, when choosing and buying, the question often arises: what is the difference between systems with a check valve.

A non-return valve in fans is essential. This part prevents ventilation air from entering the room. This happens when reverse thrust occurs, for example, in a strong wind.

But this does not mean that the check valve is a mandatory part of the design. Because fans with such a valve impede normal ventilation of the premises. To compensate for this, the fan with a non-return valve will have to be kept in working order at all times.
