ABSTRACT:
An adaptable, temperature-responsive, powered-fan, foundation ventilator apparatus includes a louver housing defining an air passageway, construction for selectively opening and closing the louver housing air passageway depending upon the temperature, a fan housing defining an air passageway communicating with the louver housing, structure for mounting a fan at the rear edge of the fan housing, a fan carried by the fan mounting structure, a fan orifice plate disposed across the air passageway of the fan housing and defining an orifice through the orifice plate, and a fan that includes a fan blade operatively disposed in the orifice of the orifice plate. The apparatus further includes a flexible elongated duct that connects the fan housing to locations which are obstructed from direct flow to the fan housing. The apparatus further includes a flexible adaptor hood which adjustably connects to the fan housing and to the flexible duct and is configured for easy storage in inventory.
