Application of Fans in Commercial HVAC Equipment

2020-7-30  fan, as the fan remains at constant rpm and the static pressure is decreased, the brake horsepower requirements of the fan will increase thus “overloading” the fan and motor. Figure 4 shows the difference between an overloading type fan (FC) and a non-overloading type fan (AF). The FC fan increase in bhp at constant rpm can easily be seen.
