TerraBloom Fan Speed Controller For Booster Inline Exhaust and Duct Fans. Blower Airflow and Motor Speed Adjuster. Rated For Up To 350W. Continuous Dial Rheostat Control

#ad
TerraBloom #ad - This speed controller will allow you to slow down your 6", 8" or 10" booster fans by 25-40% percent from Max Speed. Speed controller for booster fans: designed and tested to work with terrabloom booster fans. Key stats: current capacity: 3. 5a, voltage capacity: 120v, rated for up to: 350w.

Each fan has a speed range that it can operate in, it'll start making "humming" noise, typically the more powerful the motor, the larger the speed range it will have until it starts to "hum". Note on "hum" sound: if you slow down your fan too much, which signals that the motor is not getting enough power. 4" booster fans are very quiet even at max Speed, this controller will only let you slow it down by only 10-15% due to low powered nature of its motor. Check for compatibility: this fan speed controller won't work with box fans or Any Fans which have a built-in speed controller or speed settings.

Warranty: we provide 1 year warranty on these variable fan speed controllers. Slowly turn the knob the highest point to gauge the range of your fan's motor, its lowest safe speed is right before motor starts to "hum". This speed controller's "High", "Low" marks are for reference purpose only. Durable 3-pole grounded plug construction, no extra Wires To Deal With. Mixing two speed controllers on one fan causes compatibility issues.
