Product Description

An intelligent inline duct fan made for air delivery projects to cool or ventilate AV closets and grow rooms. By circulating air and boosting heating or cooling, this powerful fan exhausts stale and odorous air and replaces it with fresh air to keep spaces feeling comfortable. The active exhaust fan is equipped with an inline speed controller, featuring PWM controls and 8 speeds with a simple button press operation. Along with an EC motor is a mixed flow design that combined, allows the booster fan to run efficiently and ensure a quiet operation. Cleaning and maintaining this duct fan are made easy thanks to its easily detachable motor box. The complete package includes the inline duct fan, speed controller, AC power plug, mounting hardware, and a user manual.

Speed Controller with Memory Function

Each inline blower fan includes a precise speed controller that allows you to set the exact fan speed for your application. It is supported by a pulse width modulation (PWM) controlled EC motor, which helps the duct fan to run smoothly at low RPM speeds. Compare this to common AC-powered duct fans which suppress voltage to control fan speed, resulting in motor noise and heat. The fan controller has a push button that includes 8 precise speeds and an on/off switch. It also features memory capabilities that retain the current fan speed when the inline fan is turned off and back on.

Made for Silence and Energy Efficiency

The mixed flow design uses a stator blade and dual hydrodynamic wind circles to bring you the most efficient performing inline duct fan. This construction gives it a high static pressure rating which enables airflow delivery for applications with highly restricted air movement. Dual ball bearings with a 67,000-hour lifespan permits mounting in any direction, and the IP44 rating ensures protection against moisture and dust.

Applications

This mixed flow inline fan is a versatile tool that can be used in a variety of HVAC applications. Its low noise performance lends itself well to projects that require discreetness. Primary functions include cooling and ventilating hydroponic grow tents and grow rooms to facilitate ideal conditions for your plants. Typically set near the ceiling where heat rises, the inline duct fan exhausts stale air and odor while passively taking in fresh air.

Aside from growing projects, other uses for the inline duct fan include home ventilation for rooms like:

  • Bathrooms
  • Attics
  • Audio/Video Equipment Rooms
  • Server Closets
  • Rack Cabinets
  • Whole House
