® Factors Affecting Air Performance System Effect The Air Movement and Control Association (AMCA) International defines system effect as “a pressure loss which recognizes the effect of fan inlet restrictions, fan outlet restrictions, or other conditions influencing fan performance when installed in the system.” Duct elbows, transitions or other disruptions to uniform airflow may contribute to system effect. Unducted fans may be affected by proximity to walls, beams and other obstructions to airflow. System effect is very difficult to quantify and correct. Frequently the only means to correct the resulting poor performance is to increase the fan speed or increase the blade pitch. These corrections may increase horsepower requirements beyond the capability of the motor. Also, the system effect may be so severe that the fan is not capable of the higher static pressures required. The diagrams below show some more common causes of system effect. For a quantitative discussion of system effect, refer to AMCA Publication 201. 3 Fan 2 ½ Duct Diameter Turning <strong>Vane</strong>s Good Good Poor Poor D Good Good Poor Poor Ducted Inlet Conditions One Fan Diameter Inlet Bell Good Good Poor Poor Non-Ducted Inlet Conditions Length of Straight Duct 2 ½ duct diameter Good Poor Ducted Outlet Conditions Two Fan Diameter Outlet Cone Good Poor Non-Ducted Outlet Conditions 3
