The exhaust fan is a common fan in the home, and it has no weight and volume like the centrifugal fan and the axial fan, and is relatively light. Here is a detailed introduction to the exhaust fan.
First of all, let's look at what the exhaust fan is used for. The exhaust fan is mainly used to eliminate the occurrence of harmful gases in the room or space, and maintain the internal negative pressure to prevent the diffusion of harmful gases from polluting other rooms or spaces. Harmful gases refer to gases that have an impact on the air environment inside the building, such as dirty air in toilets, moisture in boiling water, smoke in smoking rooms, soot in kitchens, and automobile exhaust in garages.
Turbine exhaust fans are divided into two types: turbine exhaust fans and negative pressure fans;
Whether it is a turbine exhaust fan or a negative pressure exhaust fan, ventilation is achieved by exhausting indoors or outdoors.
