  • the electric motor from the alternating current main with a power of 100 - 400 W;
  • aerodynamic impeller with blades;

  • their hulls are strong and durable;
  • simple device makes it easy to repair and maintain.

The drawbacks of wall fans are the selection of free space in the kitchen, the need to make reliable fixtures in the wall or on the ceiling, a higher noise level and power consumption than channel types.

A separate type of wall fans is a snail model, so named because of the appropriate shape. A similar design was invented to effectively move large volumes of air using a rotor with inclined blades and a spiral casing. The aerodynamic impeller in the cochlea is made of durable and lightweight steel, and the casing is aluminum. The construction itself is very simple and easily repaired, and you can hang it in the kitchen in the right place. These types of fans are used mainly in large premises and industrial workshops, but for domestic purposes there are also small kitchen models with dimensions of 25–50 cm, a power of 200–300 W and a noise level of no more than 35 dB.

Window fan It has approximately the same device as the channel one, only its body can be narrower in order to fit comfortably in the window thickness. He performs air exchange with the street, which, even in comfortable weather, is successful, since fresh street air comes into the room, and not odors from other apartments through the ventilation shaft. But in the bitter cold it can create an unwanted cold in the kitchen. Installation of such a device in a window opening can cause difficulties: it is necessary to fix it comfortably in the window, to supply power.

Ventilation installation

It is easiest to mount duct fans because of their small mass and dimensions. First of all, it is necessary to calculate that the case fits into the ventilation hole of the kitchen. This is usually not a problem, since communications in typical apartments and duct fans have certain standards for size. The hardest part of such an installation is wiring the cable to power the device. If you can’t do it yourself, it’s enough to call an electrician to connect one point to the required place.

Then the face shield of the fan is attached to the wall around the vent. This is best done with dowels and screws in the concrete wall. 4 holes are needed - at the corners of the front case. For modern models due to their lightness and internal protection against the vibration of this fastener is enough.

Tips for choosing and installing

It is necessary to buy a fan model for the kitchen, first of all in terms of its capacity. For these devices there is a special value - the rate of air exchange, which is determined by the ratio of the volume of air entering the air and the volume of the room for 1 hour. For kitchen varieties, this figure is 6 - 12. By multiplying the air exchange rate for this unit by the volume of the kitchen, you can get its working capacity. It determines whether the fan will cope with providing fresh air in the room.

In technical data sheets of devices the working power in watts can be indicated. But it is not a decisive indicator of efficiency, the size and shape of the blades, the type of casing and check valve, the speed of rotation and the direction of flow also affect the air exchange.

Most modern models of kitchen fans have a noise threshold of 35 dB, which is slightly above the noise level of whisper - 30 dB. It is worth choosing not only powerful, but also noiseless goods that will not bring discomfort from annoying sound.

Fans from time to time need to clean the blades and protective grills. Therefore, it is necessary to take into account when purchasing the ease of access to these items.

Any type of fan must be installed at the top of the kitchen - closer to the ceiling, where the stale warm air is most concentrated. But do not install the device in an area where the air temperature is more than 50-60 ºС, from which the parts and the working part can become unusable. The places of electricity supply to the fans must be reliably insulated and protected from moisture.
