Description

Inline Duct Booster Fan

The quiet duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Contains a DC-motor with PWM-control for a 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. Includes an intelligent controller that features advanced programming and functions. This 4 inch duct fan kit also includes two clamps and everything needed to mount the unit and power it through an outlet.

Intelligent Controller

The controller features an on-board processor with active temperature monitoring that will automatically adjust fan speeds to respond to varying temperatures. For non-cooling ventilation applications, the controller can be set to run continuously at customizable speeds with power on-off memory. Additional features includes an alarm system and eco-mode. Includes detachable 8-foot precision thermal probe that is water resistant.

Quiet and Energy Efficient Design

Features a DC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables the duct fan to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design for a high static pressure rating. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.

Applications

This ventilation duct fan is popular for a variety of applications including cooling AV equipment rooms, closets, racks, or cabinets. It's also used in various air circulation or ventilation projects including hydroponic grow rooms or tents, exhausting bathrooms or attics, and any other air movement applications.
