How are fans categorized according to airflow movement? Mainly divided into centrifugal fans, axial fans and inclined flow (mixed flow) fan 3 kinds, the followingRoots FansI'll take you through it.
1. Centrifugal fan
The gas stream enters the rotating blade channel, where the gas is compressed by centrifugal force and flows in the direction of the radius.
2、Axial flow fan
Airflow axial into the fan impeller, after the rotating blades in the flow channel along the axis of the direction of the flow of the fan. Compared with centrifugal fans, axial fans are characterized by high flow rate, small size and low pressure head, which should be noted when used in dusty and corrosive gas situations.
3、Slant flow type (mixed flow type) fan
In the impeller of the fan, the direction of the airflow is between the axial flow type, approximate flow along the cone, so it can be called oblique flow type (mixed flow type) fan.
