The difference between centrifugal fan and axial fan is as follows: 1、The centrifugal fan changes the flow direction of the medium in the air duct, while the axial fan does not change the flow direction of the medium in the air duct; 2、The former has large air volume and pressure, while the latter has low air volume and pressure; 3、The former is more complex to install, while the latter is simpler to install; 4、The former is generally connected with the fan through the shaft, while the latter is generally in the fan; 5、The former is often installed at the inlet and outlet of air conditioning unit, boiler drum, induced draft fan, etc., while the latter is often installed in the air duct or at the front end of the air duct outlet.
