The bathroom is the location of the body's relaxation. A person relaxes and rests from daily problems enjoying peace and peace. To feel as comfortable as possible, the room must be optimal humidity. Improving air flow circulation is due to the exhaust for the bathroom and the toilet.

Types of equipment

There are two main classifications of fans in the bathroom:

• according to the design features;
• according to the principle of action.

The first classification implies the division of ventilation devices to:

• centrifugal;
• axial.

The centrifugal fan consists of a blade wheel, which is placed in a spiral casing. Under the influence of centrifugal force air flow:

• penetrate the channels located between the blades;
• move into the casing;
• they are sent to the outlet.

In most cases, centrifugal fans are made of plastic. The main advantages of using centrifugal fans include:

• low weight;
• silent work;
• high performance.

Axial fans for drawing in the bathroom in the structure differ from centrifugal devices:

• the location of the blade wheel in a cylindrical casing;
• moving air axially.

Advantages of axial equipment:

• easy installation and maintenance;
• maximum efficiency;
• possibility of changing the direction of airflow.

The operating principle of the fans are:

• standard;
• automatic.

Standard devices are equipped with a check valve. With it, the exhaust air is interlocking. Starting a standard fan is made by inclusion in the electrical network. When the air humidity in the room stabilized, the equipment also turns off in manual mode.

But there is one nuance. Standard fans will not be able to quickly ventilate the room with an elevated moisture content. This will cope with automatic hood in the bathroom. Such devices are equipped with timers or hydrostats.

Hoods with a timer are installed for a certain period of time. The principle of functioning of equipment with hydrostat is as follows. A special fan sensor independently determines the humidity indicator and is triggered in the case of enhanced humidity.

Criterias of choice

When purchasing products, their wide range of many people often puts in a dead end. This also applies to the fans in the bathroom. Among their diversity, choose the most suitable device can be based on acceptable technical parameters.

There are such basic requirements for which close attention should be paid when buying an exhaust to the bathroom:

• security;
• power;
• dimensions;
• noise level;
• compliance;
• warranty.

In essence, the fan is a device working with electricity. Due to the fact that the bathroom is characterized by high humidity, a hood should be purchased, which is intended for the environment. The device must be absolutely protected from moisture so that it does not become a source of damage to the current.

The optimal performance of the forced hood in the bathroom is up to 100 cubic meters / hour. It is impossible to install a weak equipment for the equipment in a large area of \u200b\u200bthe room. It will not give the necessary effect. Therefore, it is necessary to pre-explore the technical characteristics of the fan and compare them with the size of the room.

The best option is to buy a compact and powerful device, which in the lowest time will effectively engage in air cleaning. The embedded hood must easily be located in the walls of the walls, where wet air will be removed in the ventilation channel.

An important condition for a comfortable pastime in the bathroom is to install a low-noise exhaust. Models of fans make noise 25 dB and more. When buying, you need to choose a hood with a minimum value, considering other technical specifications of the device.

The presence of certificates, labeling with the security class and warranty documents - all this is also taken into account when selecting fans. The minimum allowable protection class of the equipment body must be ip 34 (from foreign objects that have a size of more than 2.5 mm, and water drops on any side).

Among the sets of brands that are engaged in the manufacture of ventilation devices, three manufacturers should be allocated:

• MISO (Germany);
• UliisNT (Italy);
• Soler & Palau (Spain).

The most reliable, efficient and silent hoods produce specialists from the German company Mixo. In addition to reliable operation, the Italian fans of the ELIESNT (by the way, the sub-worn Mixo) are characterized by a magnificent ratio of the price-quality indicators. Soler & Palau more pays attention to the incarnation of original design solutions. Especially highlighted exquisite models of the serial series Silent.

Installation of ventilation devices

Installation of drawing in the bathroom provides compliance with several rules for carrying out work. In general terms, they concern:

• the correctness of the ventilation;
• ability to dismantle equipment if necessary.

Naturally, a completely wrong solution will be the extraction of hoods closer to the floor. It will have the best efficiency when it is located at the highest point (as far as it is possible), that is, near the ceiling.

Despite the presence of a special waterproof case, the hood is best to set away from the shower and other mixers. Water should in no way fall into the device. You should also correctly install valves or grids that prevent reverse air.

Mounting work should be done so that the fan is subject to light disassembly. Over time, you will have to deal with cleaning and lubrication. And sometimes repair.

It is not necessary to attract specialists to work on installing the fan, and make the installation of drawing with their own hands. Although this process is simple, it is necessary to carry out a number of preparatory work. These include:

• laying an electrical cable;
• adjustment of the ventilation channel;
• coupling with an electrical network;
• installing the fan in the channel;
• climbing with mounting foam and putty.

The setting itself depends on its type. The axial fan of plastic is mounted directly to the ventilation channel. Work that will take about 15-20 minutes consists of such consistent actions:

• the facial cover of the device is removed;
• installation site is flashed with silicone;
• the fan is inserted into the hole and pressed against the wall;
• with the help of self-tapping screws, the facial cover is mounted.

If the ventilation channel has drawbacks (too huge length, one-tube ventilation system, the channel is scored, etc.), it is better to use centrifugal fans. They are also installed under the ceiling, after which they are closed with plasterboard.

Devices are mounted in the middle part of the air duct or before the intake hole. The first option assumes the presence of a fan with a maximum power. In the second case, the installation of an additional device is required, thanks to which the condensate cannot get into the overall ventilation system.

Reduce the noise effect from the fan operation in two ways:

• searcate the channel with elevated sound insulation properties;
• behind the device install a special silencer.

High-quality and timely installation of an exhaust will save the bathroom from excessive moisture and unpleasant odors, which can cause mold, fungus and the appearance of harmful insects.
