Improving Fan System Performance

2013-8-26 · Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in "clean air," low-pressure, high-volume
