How to choose a window fan? Exhaust window fans.

Before you install a window fan, you need to evaluate it technical specifications and capabilities, as well as the dimensions of the room where installation is expected. Modern systems have a reduced noise level (25-30 dBA) and will not cause any unpleasant sensations. Expending a small amount of electricity, they at the same time provide significant air exchange that meets sanitary standards.

For a simple device and reliable design Window fans do not require expensive service - it is enough to periodically clean the dust from its parts.

Installation

Installing a window fan is a simple process and will not take much time. The device is lightweight and small in size, which allows it to be installed directly in a window by cutting a hole of the appropriate size in the glass. In order to ensure a tight fit of parts and assemblies at installation sites, special components and fasteners are provided to ensure complete tightness. To eliminate noise, noise-insulating gaskets are used, which are also advisable to use during installation.

How to choose

In order to accept correct solution, Particular attention should be paid to power, performance and size– these parameters are of particular importance during installation and further operation. Most popular option is an axial window fan, characterized by its simple design, high efficiency useful action, good aerodynamic characteristics.

When choosing, the volume (m3) and purpose of the room are taken into account. So, for a bedroom, an air exchange rate (number of air changes per hour) of 2-4 is sufficient, for a living room - 3-6, for a toilet - 6-10, for a kitchen - 10-15. Based on the required air exchange rate, you can calculate the required system performance by multiplying the specified parameters. So, for a kitchen of 10 m2 you will need an appliance with a capacity of at least 100 m3/hour.

An analogue of window fans is a vent fan, which is installed in vents and performs the same functions. In accordance with the size and shape of the window, you can choose exactly the device that is most suitable in a particular case. A separate, high-tech model of this type is a vented supply and exhaust fan, which provides ideal cleaning capabilities and fresh air supply. To protect against the penetration of outside air in the “off” position, it is recommended to purchase an inexpensive vent fan with a cover.

The size of the device must correspond to the size of the window or vent, without occupying too large an area and without interfering with penetration sunlight. It is also important that the shape and design of the device fit into the overall interior.

To ensure the removal (inflow) of air in large volumes, in some cases three-phase window fans can be used. Such fans have increased performance characteristics and are used as auxiliary facilities.

Kinds

Depending on the direction of air movement, window fans are divided into:

• exhaust;
• inlet;
• supply and exhaust.

Important!
Exhaust fans provide extraction of particularly contaminated air. This category includes kitchens, bathrooms, toilets, small laboratories and workshops.

Window supply fan will help solve issues of fresh air flow into the office, living rooms, where there is no need to pre-extract contaminated air, but slightly high blood pressure fresh supply air will help refresh the air in the room.

Particularly effective is the supply and exhaust system, which simultaneously ensures the removal of polluted air and the influx of fresh air. A reversible window supply and exhaust fan can perform these functions. Depending on the need for cleaning or fresh air supply, devices of this type can perform both specified operating modes. For this purpose, the device is equipped with a reversible electric motor powered from a 220 V network.

Household devices are characterized by low power. They consume 15-25 W. On the other hand, their design provides low level noise.

Window fan with blinds

A household exhaust window fan makes up to 3 thousand rpm. Such fans are well suited for operation under significant temperature differences between indoors and outdoors, which reach a maximum in winter. Changing weather conditions also do not affect the performance of these fans. The housing and main elements of the fan are made of plastic, resistant to various influences - high temperature, shock, ultraviolet rays. It can be operated at temperatures from +50°C to -50°C.

An important issue is heat retention. For this purpose, a window fan with blinds was developed. An alternative to blinds is a cover. Louvered fans close when the motor is switched off. To eliminate gaps between the body and the window, sealing strips are provided from soft rubber. For fans with a lid, when it is closed, the motor turns off, which simplifies control of the device. The advantage of this design is the absence of reverse thrust.

Fan selection

The main question when choosing a fan is the purpose of its use:

• For the kitchen, bathroom and toilet - exhaust type fans are suitable.
