3 basic types

3.1

fan airflow direction according to the motion classification can be divided into centrifugal and axial fan, see definition in JB/T 2977.

3.2

Fan pressing force can be classified into low, medium, high pressure fan, see definition GB/T 19075.

3.3

Fan can be divided according to the direction of rotation clockwise and counter-clockwise rotation, see definition in JB/T 2977.

3.4

Press fan lubrication can be divided into grease and oil lubrication.

3.5

Fan bearing type can be divided according to Rolling and plain bearings.

3.6

Press fan support can be divided into cantilevered and double support type, see definition in JB/T 2977.

3.7

centrifugal fan by way of the intake points for single suction and double suction, see definition in JB/T 2977. Single or double suction fan suction points

Is not brought into the gas tank (axial intake Figure 4) and into the gas tank (radial intake Figure 5).

3.8

Axial Fan Press series can be divided into single-stage and multi-stage axial fan axial fans.

3.9

If the axial fan blade adjustment, can be divided into stationary blade rotor blades adjustment and regulation. See definition in JB/T 2977.
