Differences between axial flow fans and centrifugal fans:

Structure: the centrifugal fan adopts volute type, Axial fan adopts cylinder type

Property: the centrifugal fan with the same impeller diameter has higher wind pressure and lower noise than the axial flow fan

Impeller: the centrifugal fan is multi-blades forward or backward inclined type, while the impeller of the axial flow fan is mostly 4-blade and 6-blade.

Price: the price of centrifugal fan with the same impeller diameter is higher than the axial flow fan;
With the advancement of technology, the requirements for wind pressure and air volume can be achieved with no special requirement on fan types
