ActiveFans—Efficiency classification for fans—Part 3: Fans without drives at maximum operating speed
通风机 通风机效率等级 第3部分：不含驱动装置最高转速时的通风机
Application Summary AI generated
This standard specifies a method for classifying the energy efficiency of fans tested without their drive components (such as motors or belts) while operating at their maximum rotational speed. It is applied by manufacturers and testing laboratories to evaluate and label the intrinsic aerodynamic efficiency of the fan impeller and housing assembly, independent of drive losses. The classification is used in industrial ventilation, HVAC, and process air systems to compare fan performance and support regulatory compliance for energy efficiency.
