Room ventilator inlet

This invention relates to room ventilation systems. In particular, it relates to a wall or ceiling-mounted outlet to exhaust air from a room in a building, such as a bathroom or toilet room, through a central vacuum system. A room ventilation air inlet is mounted in a wall or ceiling to operate in conjunction with a central vacuum system as a suction source. Activation of a suction source connected by conduit to the inlet draws air from the room, removing odor and moisture. The air inlet has a valve to seal and open the air inlet. A single lever actuates both the valve and the central vacuum system.
