An axial flow fan moves air or gas parallel
to the axis of rotation. By comparison, a centrifugal or radial flow fan moves
air perpendicular to the axis of rotation.
More accurately, an axial flow fan uses a propeller to draw the air into it, and discharge it, in the same axial direction. axis of rotation. Therefore, the axial flow fan is better suited for low-resistance, high-flow applications.
Usually you can see the axial flow fan in places need to keep the air flow in the closed room. For different purposes, the might be not only one axial flow fan and also the output could be higher or lower according to the situation.
Somebody might be confused with the difference between axial flow fan and centrifugal flow fan due to its similar shape. Maybe you can just descrbe your demand to the technician and ask them to choose which type is the right one for you.
