  • What's Included
  • Imagine being able to walk into a room, press a button and have the airflow only to that room immediately boosted by up to 80 percent-quietly. 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 4-Inch In-Line Duct Fan uses high-performance balanced polycarbonate 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.

    Good fan for what I used it for. If this is someone trying to boost a lot of airflow this is not the fan for you. I used it on a solar furnace where I want the air to move through it slower so the heat does not disapate fast. Works Great!

    Item ordered was shipped quickly. The fan is fairly quiet (considering it is inside a tube) and as powerful as expected.

    Service and shipping was great. The price for the fan was a great price. The reason for only 2 stars was because the longer the fan runs it starts to make noise. Proably not woth the shipping cost to send back for replacement.

    The inline duct booster fan is quiet and easy to install. It doesn't move much air but to me that is a desirable feature.

    Excellent fan for the price.... I previously used bathroom ceiling fan for my application and now I can move more air on a continuous basis. Easy to install and simple to hook up. Thanks. Jim Walder
