Variable fan speed increases 

the life of the fan and motor

Typically, CRAC fans run at a constant speed and deliver a constant 

volume of air flow. Adding a Variable  Speed Drive to the fan motor 

allows fan speed and power draw to be reduced as load decreases.  A 20 

percent reduction in fan speed provides almost 50 percent savings in fan 

power consumption.
