ABSTRACT OF THE DISCLOSURE An apparatus is provided which combines in a single, relatively compact housing the necessary components to efficiently exchange stale room air with fresh outside air. The apparatus includes a single, continuous duct having openings at each end. A heat storing matrix is disposed within the duct. A fan is also placed within the duct. The fan is capable of producing a substantially axial air flow through the duct. The fan is moveable between two positions: a first position wherein air flow is in a direction from the first end to the second end of the duct and a second position wherein air flow is reversed. The apparatus includes means for moving the fan from the first position to the second position such as a solenoid.
