Axial flow fans 1.0 definition of axial fans an axial flow fan moves air or gas parallel to the axis of rotation. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Blades fixed with separate steel bolt (s) to. Fans are generally classified as centrifugal, axial, mixed, or cross flow.
