Variable Frequency Drive (VFD)

The variable frequency drive system is an ideal choice for variable torque applications like centrifugal fans and pumps. Control your fan’s motor with this 500-horsepower VFD. The technology of this variable frequency drive will greatly improve the energy efficiency of your fan’s motor, and typically pays for itself in a matter of months. Even a very small reduction in speed will result in a large reduction of required horsepower. The variable frequency drive features:
