Abstract: A method and apparatus for use in a room for circulating the air, for substantially balancing the temperature of the air distributed in the room, and for treating the air. The apparatus comprises a body having an interior cavity. The cavity is provided with an air-circulating fan assembly and air treating component. The air treating component may be hollow and may include filtering, deodorizing, and scenting material. Strategic placement of the apparatus within a room allows for substantially balanced room temperatures.

Abstract: A heat distributor for equalizing the temperature gradient of a room. A housing is supported on a gridwork of a suspended ceiling. Warm air from near the ceiling is drawn through a perforated panel and an air filter mounted in the housing. An electric fan directs the warm air downwardly through a baffle having a conical flange to form a column of warm air which is directed to the floor. A rotatable, perforated disk has wedge shaped walls to compress the air and direct the column of air to a targeted area below. A source of ultraviolet radiation is installed in the housing to sterilize the warm air.
