The AireShare™ ventilator system is designed to distribute heated or cooled air from room to room through interior walls or level to level through floors and ceilings. It provides homeowners with an unobtrusive way to circulate heated or cooled air from fireplaces, stoves, electric baseboards, split system ductless a/c, and window a/c units to adjacent rooms. The net result is extended comfortable living space from existing heating or cooling equipment. With room-to-room models, the blower draws heated or cooled air into an open wall cavity and distributes it to an adjoining room through a streamlined air diffuser installed on the opposite side of the wall. The intake blower and diffuser can be located high or low in the wall for airflow control and optimum comfort. The level-to-level model moves air up or down from one level to another through a sleeve that adjusts to floor joist/truss thickness.
