Variable Frequency Drives on Air Handling Units Information Sheet

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. This allows for greater energy savings and an extended life of the motor.
