Abstract: An exhaust air shutter assembly may include a housing having a dividing wall separating the exhaust air shutter assembly into an inside portion and an outside portion. An opening may be formed in the dividing wall and a frame may be mounted around the perimeter of the hole. Disposed on the frame may be a gasket that extends around the entire perimeter of the hole. The exhaust air shutter also may include at least one shutter flap mounted adjacent to the frame with a hinge such that the shutter flap can pivot between a closed position and an open position. When the shutter flap is in the open position, an air flow path exists from the inside portion of the exhaust air shutter assembly to the outside portion. When the shutter flap is in the closed position the air flow path is blocked. The shutter flap is configured to contact the gasket mounted to the frame when the shutter flap is in the closed position, thereby creating a seal between the shutter flap and the opening in the dividing wall.
