ABSTRACT:
A fan-equipped air delivery vent for installation into a structure in order to enhance the flow of air from a heating/cooling system includes a main housing portion arranged as a generally rectangular box having an air entrance side closest to the heating/cooling system main blower and an air exit side closest to the interior of the room or space which receives the heated or cooled air. Positioned across the air exit side of the main housing portion is a covering register panel which is arranged with two sections of air-flow louvers. Positioned across the air entrance side of the main housing portion is an enclosing panel which has three air-entrance apertures positioned therein. Mounted to the enclosing panel and positioned within the main housing portion are three electric fans which are wired in parallel and controlled by an ON-OFF switch and thermostat. Each of the three electric fans is positioned in alignment with a plurality of louvers on the exit side and with one of the three air-entrance apertures on the inlet side. The enclosing panel and the defined air-entrance apertures ensure that virtually all of the air delivered by the heating and cooling system will flow through the three electric fans and that the fans will conduct relatively clean filtered air. The backflow of dirty air across the tips of the fan blades is restricted by the design of the air delivery vent.
