Duct fans allow maintaining an optimal microclimate in homes and industrial premises. They are electrical appliances consisting of a housing, motor and impeller. The main task of the duct fan is to move air masses along the ventilation ducts. This can be the removal of polluted air from the room or the organization of the influx of masses from the street. In each specific case, a device with a specific set of technical characteristics is required. Expert advice will help you make the right choice.

How to choose a duct fan

1. The size. First of all, you should decide on the size and shape of the bends. The easiest way to do this is when the ventilation system has already been installed. For round pipes, a duct fan with outlets of the same shape and suitable diameter is selected. In the case of square or rectangular shafts, it is better to buy appropriate fans.
2. Performance. The second important parameter is performance. The technical characteristics indicate such an indicator as air exchange. It can fluctuate in the range of 100-2000 cubic meters. m / h. For a private house, a duct fan with a capacity of 100-500 cubic meters looks optimal. m / h. But for retail and commercial premises, more powerful models are required (1000-2000 cubic meters / h).
3. Engine power is not always directly proportional to performance. The more powerful the motor, the easier it is to pump air, the less the load on its components and components. The power range ranges from 10 to 500 W, it is better to choose models with a small margin. For example, if the project specifies a 130 W fan, then it is optimal to set the 150-160 W model.
4. Noise level. For residential premises, the noisy operation of the device can become an urgent problem after the installation of the ventilation system. Manufacturers indicate the noise level in dB (15-100). Many users, from their own experience, consider electrical appliances with a noise level of up to 40 dB to be low-noise models. A higher sound load begins to strain, especially when the duct fan is directly in the room.
5. Materials. As for the materials used in the manufacture of devices, most often manufacturers use plastic and metal. Steel casings and impellers are considered more reliable, but they weigh more and are more expensive. Plastic products benefit from quiet operation, lightness and low cost. Owners of private houses prefer to buy them, despite the lower strength.
