The Fresh Air In-Forcer™ is an effective, affordable way to supply fresh outside air to dilute trapped pollutants and replace air vented by exhaust fans and fuel-burning equipment in residential structures, said the company. The system consists of a fan and exterior hood that can be installed through a 4-inch, round exterior wall opening. Operating control options include manual operation by plugging into to a 115-vac switched outlet, plug-in timer operation for a desired schedule, or dehumidistat control operation. Standard 4-inch flex or metal duct may be used for ducting. The quiet, high-efficiency, 90-cfm fan consumes 18 W.
