Active Air Duct Fan Speed Adjuster

Hydrofarm’s Fan Speed Controller was designed especially for centrifugal fans. This means it will help prevent damage to fan motors, ensuring longer life. (Meant for use with permanent split capacitor type motors, all Hydrofarm inline fans, and Active Air booster fans.)

It will correctly and precisely adjust the speed of centrifugal fans without causing the motor to hum. These controllers are more sensitive than any on the market, and are compact and built to last.
