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 up 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 the nylon strap (for flexible ducts) or sheet metal screws (for ridged ducts). This 6 inch in-line duct fan uses high-performance balanced polycarbonate fan blades, and the fan comes with approximately 6-inch wire leads.
