iPower 8 Inch 745 CFM Inline Ventilation HVAC Vent Blower Fan and Exhaust Variable Speed Adjuster Combo Set for Indoor Gardening, 8" Fan & Speed Controller

Specification: size: 8inch, voltage: 110V, frequency: 60Hz, power: 120W, air velocity: 745CFM, speed: 2600RPM, noise: 69dB.
High tech design: the aerodynamically designed centrifugal impeller is driven directly by rotor of that delivers strong air flow, moves air through target location efficiently for optimal ventilation, to minimize noise and extending service life.
Saves space: built-in junction box which greatly saves space. Made of high-quality metal, strong and sturdy.
The control switch for 3 settings: speed adjuster has variable speed, OFF, HIGH, MED, LOW. To avoid the risk of burning out the fan motor, controller does not adjust below 50%. It is NOT suitable for shaded pole motor and brushless motor fan.

The iPower Inline Fan is composed of the chassis, impeller, external rotor motor.
1. Chassis: is made of high-quality, cold-rolled steel. The surface is treated with a kind of plastic sealant to provide a strong resistance to corrosion. CAD optimizations on the flow channel design to allow the impeller performance at its greatest efficiency. Inlet and outlet diameter flanges are easy to install, repair and clean.

2. Impeller: the curved-end blade impeller works with the fan casing in harmony; the fan can produce maximum air flow and efficiency while minimizing noise.

3. External Rotor Motor: a single-phase asynchronous external rotor motor is located on the chassis. The impeller is attached directly to the rotor motor by die-casting. The impeller is driven directly by rotor to minimize noise while providing high airflow and extending service life.
