A standard fan for a natural circulation hood does not always cope with its work. This hood is of particular importance for the bathroom and kitchen. To solve ventilation problems, use exhaust duct fans . Small size and low noise level make these devices one of the most popular in Ukraine.
How it works
Silent ventilation device for any type of room consists of an electric motor, a rotor wheel, blades and an electronic control unit. But unlike usual fans, duct models have their own characteristics. These characteristics include the ability to accurately match the diameter of the device to the ventilation hole.
Also, these types have a check valve and a temperature sensor. Thanks to this, the fan can block the return air flow, and the thermal sensor prevents the system from overheating.
The principle of operation of a duct fan is quite simple. After starting the electric motor, the impeller starts to rotate. The air entering the device moves in the desired direction at high speed. You can control the operation of the engine using a special switch that allows you to adjust the number of revolutions of the thermostat and impeller. This in turn allows the engine to run without overheating.
What to look for when choosing a fan model?
Stores offer different models of devices that are suitable for ventilation in domestic and industrial premises. When choosing a fan, pay attention to the following characteristics:
- installation conditions;
- performance;
- body shape;
- motor power characteristics;
- motor protection and control unit available.
The price also largely depends on the above indicators. But the main criterion should still be the power of the electric motor. It is also important to buy a device with all the necessary protection elements.
Paying attention to the power of the device, it is worth remembering that such a device will have high performance, but at the same time the noise level can create some discomfort. For standard household needs, it is better to choose a device with an indicator of up to 25 dB.
In the kitchen, such a duct fan should be installed in cases of a small room size. In this case, the hood, as a separate device, should not be. Also, when choosing a model, you should focus on the diameter of the duct. It must exactly match the dimensions of the case.
