Essential Info

Imagine being able to walk into a room, press a button and have airflow to that room immediately boosted by up to 80% and to all be done quietly. The Suncourt In-Line Duct Booster Fan increases ventilation to selected areas and equalizes temperatures in rooms that are too hot or too cold, or build your own power-circulated HVAC system. Installation is easy: simply cut the flexible or rigid duct where you want the fan installed, insert the duct, and then seal the duct with a nylon strap (for flexible ducts) or sheet metal screws (for rigid ducts) and plug in the 110V AC power cord. This 6-Inch In-Line Duct Fan uses high-performance balanced polycarbonate fan blades, and the fan comes with approximately 6-inch wire leads.


What's Included

  • 6-In 110VAC 250CFM In-Line Duct Fan - DB200
  • More Info

    In-Line Duct Fans can be wired directly to a wall switch for manual control or to an HVAC system (an optional 110V relay may be required). To turn on the duct fan automatically only when there is air flow, just add the DuctStat Duct Fan Thermostat, sold separately. The DuctStat requires that the duct fan have a 110V plug end.

    JEFFREY -- pennsdale, PA   2/2/2013
    work great cheap prices
    AMBER -- patten, ME   10/19/2012
    I was very pleased with the results. The product came when we were told it would be here. A little high in cost for my liking. The product price was fine but the shipping was what on the high side but considering where it had to come from I guess I can live with it. The product was in good condition when it got it and works very well Thank you for all your help

    Look good, not installed yet.
    BETH -- greenwood, MO   5/3/2012
    We just purchased 2 of these to replace the 2 that went out in our house. Most HVAC people will tell you that these things don't do any good but they honestly cool off our upstairs so well we couldn't live without them. My daughters is a little closer to the attic door so its a bit louder but definetly worth every penny. We even had a switch installed so that we could shut them off if we needed to.
    CURTIS E -- seymour, IN   3/17/2012
    Measured only 50% of advertized air flow in free air.
    J B -- columbia, TN   3/3/2012

    STEVE -- palmetto, FL   1/2/2012
    Very inexpensive compared to others with the same specs. Easy to install. It's a bit loud, so not the best for sleeping area.

    PATRICK -- howell, MI   12/15/2011

    WESLEY -- boiling springs, SC   11/11/2011
    it is working just fine. thank you
    DAVID -- mattawan, MI   8/26/2011
    This fan is too loud. I can only run it during the day.
    MARK -- san antonio, TX   7/18/2011
    Fan worked as well as was expected. Back of the house is now as cool as the front. Thank You.
    JOHN -- westfield, MA   7/14/2011
    An easy installation within a flexible 6" supply. The amount of incerased flow was readily noticed and there is no noise from the fans (2 installed).
    RYAN -- grand blanc, MI   1/10/2011
    Would rate 0 stars if it let me. The noise emitted from this rattles through the ducting and is unusable in my opinion. Had I not cut out a section of ducting to insert this I would have sent it back. The fan is installed about 12 feet back from my register feeding a cold bedroom and keeps us awake.
    Ryan -- grand blanc, MI   1/10/2011
    Increase in air flow was noticable; however, the noise is horrific. Having installed the afn 12' back from my register beyond the 10' suggested in the instructions; I ended up with a whine/whir that will keep you awake at night. Would not reccomend.
    RAN -- canton, CT   12/18/2010
    A very large amount of noise in relation to the amount of air Easy to install
    KATHRYN -- las vegas, NM   11/26/2010
    The fan work just fine not silent but but soft.
