These Kaizen in-line duct fans are a great, and affordable, addition to any grow room for those wanting a quieter operating fan, or want reliable extraction for smaller indoor gardens.

Made from a tough and durable PVC outer case, these small, yet incredibly powerful fans can be used as an extraction for smaller grow rooms, or intake in larger grow rooms. One thing that’s immediately noticeable is the different shape to standard axial fans, this allows them to run at an increased velocity at 2010 RPM, giving greater pressure which increases the amount of air flow.

Being single speed they come pre-wired and have a fitted UK mains plug, so no need to purchase cable, a plug, get the screw driver out or worry that it’s been wired the wrong way. Simply plug the in-line fan in to a socket or timer and its ready to go. These in-line duct fans are also compatible with most speed controllers if the speed needs to be decreased.


  • Fitted with 1.7m cable with UK mains plug
  • Fan speed of 2010 RPM
  • Includes a clip on stand
  • Can be used as extraction or intake
  • Compatible with most fan speed controllers
  • 12-month warranty

Airflow rates for the in-line duct fans are as follows:

  • 5”/125mm – 335 m3/h
  • 6”/150mm – 660 m3/h
  • 8"/200mm – 900 m3/h

Available sizes:

  • In-Line Duct Fan - 5"/125mm

  • n-Line Duct Fan - 8"/200mm
