LOOKING FOR A COMPLETE AC INFINITY EXTRACTION BUNDLE?

Features an inline speed controller utilizing PWM (Pulse Width Modulation) technology. Contains an EC motor for quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. The complete kit includes one duct fan unit, one inline speed controller, an installation manual, all necessary mounting hardware, and all necessary mounting hardware.

PRECISE SPEED CONTROLLER

The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppress voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation).

This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers.

Eight-speed options are available with a power switch, and backup memory.
