Technical information Air-Conditioning Fan or Blower Horsepower Requirements

Fan horsepower Requirements

Horsepower needed for any fan proportional to the cube of the speed, provided that in the area of the drain remains unchanged. Power requirements centrifugal fan, as a rule, is reduced by reducing the area of the discharge hole if the rate remains unchanged. Power requirements propeller fan to increase the area of discharge openings decreases, if the rate remains unchanged.
