8. TerraBloom


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

TerraBloom #ad - You can exchange or return the item for any reason within 30 days from purchase date. 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, it'll start making "humming" noise, its lowest safe speed is right before motor starts to "hum".

Key stats: current capacity: 3. 5a, rated for up to: 350w. This speed controller will allow you to slow down your 6", 8" or 10" booster fans by 25-40% percent from Max Speed. Note on "hum" sound: if you slow down your fan too much, which signals that the motor is not getting enough power. Each fan has a speed range that it can operate in, typically the more powerful the motor, the larger the speed range it will have until it starts to "hum". Speed controller for booster fans: designed and tested to work with terrabloom booster fans. Mixing two speed controllers on one fan causes compatibility issues.

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. Durable 3-pole grounded plug construction, no extra wires to deal with. Use with fans not manufactured by TerraBloom or appliances other than fans is subject to compatibility, flawless performance not guaranteed in such applications. Some fans have very little adjustability range due to their motors' constrains, Voltage Capacity: 120V, such units can only be adjusted within "High" zone of the controller and will "hum" on Medium and Low settings.
