Drive down consumption with variable frequency drives on air handling unit fans

Posted By AirNW Admin Jun 09 2017

Your local utility may offer up to $300 per horsepower for qualifying variable frequency drives (VFD) on air handling unit (AHU) fan installations. Adding a VFD on a constant speed AHU fan allows the drive to match the amount of energy the motor needs for the amount of work that is being done. As the fan slows down, it draws less power than at constant speed, resulting in energy savings. This allows for greater energy savings and an extended life of the motor.

Other benefits include: reduced energy costs, reduced fan usage, long life span and precise temperature control. Contact Air Northwest to learn more about VFD requirements.
