Essential Info

Imagine being able to walk into a room, press a button and have the Airflow quietly increased by 80% immediately. The Suncourt In-Line Duct Booster Fan increases ventilation to selected areas and equalizes room temperatures that are too hot or too cold, or you can 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 12-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

  • 1x - 12-In 110VAC 800CFM In-Line Duct Fan - DB212
  • 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.

    STUART -- covington, LA   8/9/2012
    Works fine
    WILLIAM -- gold hill, OR   12/15/2011
    Very quiet. Increased Airflow to a new addition that I added to my home. Installation is easy: Simply cut the flexible duct where I wanted the fan installed, insert the duct,and then seal the duct with a nylon strap.
    BRUCE M. -- san marino, CA   8/14/2011
    Works well. As solid product.
    RICHARD -- orinda, CA   7/31/2011
    Exactly as described, well-built, and a good value for undemanding applications. These are quiet but don't move a lot of air--especially if you're using a filter.
    BRADLEY -- safford, AZ   3/5/2011
    I did the installation and it was smooth and fan works great!
    DAN -- inyokern, CA   1/5/2011
    Easy to install, works great. I am using it to move heat from a living room with a pellet stove into the bedroom.
    MAHMOUD -- richmond, VA   8/28/2010
    its very good.
    TERRY JONES -- sherman, TX   7/22/2010
    Installation was farily simple, but the fan does not make as big of a change as I expected. It does push a little more air into the rooms that I needed it to, but it doesn't make a temperature difference.
    DALE A -- west palm beach, FL   6/14/2010
    It does push a little more air into our two hot bedrooms. It just isn't cooler. So new air conditioner is in the works
    ROBERT -- lake mary, FL   3/15/2010
    Arrived on time and has satisfied the application.
    MARCIE -- conroe, TX   8/29/2009
    Loved this! Has totally improved the ventilation on that side of the house--pretty sure it has already paid for itself with a lower electric bill! Thanks!
    ROBERT -- rolla, MO   8/27/2009
    Received the item promptly and was exactly what I wanted.
    HAROLD W -- maryville, TN   1/20/2009
    Product does as expected, however the "shroud and support braces are pretty light weight and bend easily. Care must be used in handling and installation. It does do the job customer is very pleased with the results.
    CAMILLIS -- athens, AL   12/12/2008
    Very ast delivery and arrived in excellent condition.
    Darryl -- hesperia, Ca   10/15/2008
    Installed easily and Worked great for about 13 months, then the motor stopped working and the fan was out of warrantee. Now I have to spend another $60 to replace it and have someone install it. Where is the quality that will last? I'll pay a little more for one that won't break as soon as the warrantee is up.
    WILLIAM -- edgewater, MD   2/28/2008
    I had it installed within a couple of hours along with the installation of a wall switch and it has accomplished what I had set out to do. I am pleased with the purchase. Thank you. Bill H.
    John -- Michigan   2/3/2008
    Fan works, but not as well as advertised. It did help somewhat, untill it died for no reason. We have had it for 16 months and now we have to purchase a new one.
    DERMONT -- miami, FL   6/5/2007
    Airflow inproved, but not as much as expected.
    SIMON -- portland, OR   11/2/2006
    it works great
    DAVID -- west milford, NJ   8/25/2006
    Items were as advertised and worked well. Very satisfied with quality and price.
