Essential Info

Imagine being able to walk into a room, press a button and have the airflow only to that room immediately and quietly boosted by up to 80 percent. Increase ventilation to selected areas when guests are over, equalize 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. This 10-Inch In-Line Duct Fan uses high-performance balanced aluminum fan blades, and the fan comes with approximately 6-inch wire leads.

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 optional #3018 DuctStat Duct Fan Thermostat. The DuctStat requires that the duct fan have a 110V plug end. For X10 control, use a #2002SHL ApplianceLinc Module (plug-in) or #2250 Leviton Fixture Relay Module (in-line wiring) to obtain remote X10 control of the booster.

    CHARLES C. KEIS -- emporium, PA   11/16/2013
    This is actually my second booster fan. I have a wood stove and use a booster fan to move the warm air to another area. Really works well but I made the mistake of trying to lubricate the first fan. Oil and synthetic lube do not mix so I ruined the first fan and needed a replacement.
    JAMES -- double oak, TX   2/17/2012
    Fast delivery, good price, exactly what I needed
    DAVID L -- danvers, MN   10/30/2011

    DARELL -- danville, VA   7/21/2011

    EUGENE -- kansas city, MO   7/14/2011
    Made a definite difference in the amount of cold air getting upstairs. But it hasn't been quite enough.Probably need a higher CFM booster for my particular application.
    PETER -- dillsburg, PA   3/4/2011
    Absolutely awesome. The duct booster fan does twice the work as the one it replaced. Wished I had ordered a third one and would have taken advantage of combined shipping!! Thanks, Pete
    GLENN -- vacherie, LA   8/23/2010

    JAN -- silver cliff, WI   1/13/2010
    good service & fast delivery
    ABRAHAM -- pembroke park, FL   9/26/2009
    delivery was very fast and just installed, seems to work as indicated, very quiet
    Dave -- Florida   8/9/2009
    For 2 years I had two of these in my central AC system, in Florida. They made all the difference in the world, dramatically reducing AC load and therefore the electric bill. Since then, I had my ductwork completely redone. So, it sat in the garage for about a year. I then decided to fix up a window AC to my pop-up camper. I use this as an exhaust blower for the ductwork running out of the AC. Once again, works like a charm and is pretty quiet.
    GARY -- jobstown, NJ   7/19/2009
    The item was as described and worked perfectly for my application.
    JACK -- league city, TX   4/11/2009
    Installation was a snap. Added 110v relay to turn blower on with main evap blowers. Made a huge difference in the two rooms that the booster if pushing air too...great product. Thanks
    TERRY -- wichita, KS   12/19/2008
    product works great was a easy install, my sun room is warmer now
    Dan -- Michigan   12/15/2008
    Purchased a year ago...this is the second one for me as the 1st one siezed up after a year. The failure was precluded by a Lot of noise rattling/Squeaking. Sure enough the second unit is doing the same thing! I have better things to do than replace these every year and a half! I will look elsewhere for a more expensive & reliable fan.
    S. CONRAD -- south berwick, ME   11/7/2008
    Excellent product, fast shipping, great price...thank you!
    DAVID -- cheltenham, PA   10/16/2006
    Good fan so far and it seems to works well. In the summer it will really be tested
    MIKE -- medford, NJ   8/19/2006
    Installed well. Works fine. Not at all loud. As soon as I can get the time, I need to measure another area and purchase a smaller unit.
