Classification of centrifugal fans

I. Classification of centrifugal fans by pressure and function
1. Ventilator: The exhaust pressure of the ventilator is relatively small, not exceeding 0.015MPa;
2. Blower: The exhaust pressure of the blower is slightly higher, not exceeding 0.2MPa;
3. Compressor: The discharge pressure of the compressor is from 1 to 100 MPa.
Classification of centrifugal fans by working principle
1. Centrifugal fans are mainly radial flows after the airflow enters the impeller of the fan axially. This type of fan is made according to the principle of centrifugal action. The products include centrifugal fans, centrifugal blowers and centrifugal compressors.
2. An axial flow fan is an impeller in which the airflow enters the fan axially and flows approximately along the axial direction on a cylindrical surface. Such fans include axial flow fans, axial flow fans and axial flow compressors.
3. Rotary fan works by changing the volume of the air chamber by rotating the rotor. Common varieties are Roots blowers and rotary compressors.
