1 ADVANCED TECHNOLOGY FOR AXIAL-FLOW FANS WITH VARIABLE PITCH CONTROL Presented by:
2 Aerodynamic Performance Figure is a typical performance field of a variable pitch axial flow fan, showing the shape of the efficiency curves relative to a system resistance line. Areas of constant efficiency have their longest dimension parallel to the resistance line providing efficient performance across a range of load points. The resulting benefit is to minimize the net system operating power requirements. Maximum design conditions and/or test block conditions remain within the control range of the performance field.
