Essential Info

Imagine being able to walk into a room, press a button and have quiet airflow immediately boosted by up to 80% in that room. 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 ridged ducts). This 8-Inch In-Line Duct Fan uses high-performance balanced polycarbonate fan blades, and the fan comes with approximately 6-inch wire leads.

  • 1x - 8-In 110VAC 500CFM In-Line Duct Fan - DB208

    INADEQUATE! Fan does not have enough power to make any noticeable difference in the cooling effect. Waste of money, time & effort.
