    HIGH PRESSURE DUCT BOOSTER® FANS




      Versatile and durable Tjernlund M and P-Series Fans feature high pressure air handling performance with low noise and extremely low power usage.

    M-Series fans (metal housing) are ideal for long runs or air supply and exhaust applications requiring exacting performance. 

     

    Use P-Series fans (plastic housing) as ultimate bathroom/spa exhausters to eliminate fogged mirrors and lingering odors, super quiet.  They also work great for exhausting high moisture areas such as sub-slab radon gas mitigation and dryer vent boosting.

    Cyclone Series Register Booster Fans

    Save on Energy Bills and Increase Comfort!
    Register Booster fans are designed to increase the flow of heated air in warm air heating systems or cooled air in central air conditioning systems.

    Simply drop into your 4"x10" register and plug in. The unit can be operated manually or based on temperature. In winter, when the room gets too cold the unit will come on to draw more furnace heat to that room. In summer, when the room gets too hot the unit will come on to draw more air conditioning to that room. Click here for video.

    • Installs flush with floor in seconds in any 3"x10" or 4"x10" register boot opening.
