WebThe relationship of fan speed, power and flow is expressed through fan affinity laws. Using the affinity laws, one can see how the fan power consumption does directly relate to the fan speed and the flow of the air. Any given reduction in fan speed results in a cubic reduction in fan horsepower. Slowing the fan speed down to 50% may WebThe speed of a fan can be modulated by a using a frequency controller on the electric motor supply - or by changing the configuration of the fan and/or the motor disc drive.
