Active Air Fan Speed Adjuster House and Garden whitefliesHydrofarm's Fan Speed Adjuster was designed especially for centrifugal fans. This means it will help prevent damage to fan motors, ensuring longer life. (Meant for use with brushless motors, and all Hydrofarm inline fans, not 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. Features
