A casing (2) has an air intake opening (6) for a fan (3) and air outlets (7,8) for a foot-well and for ventilating a motor vehicle's interior. Behind the fan in an air-stream direction there is an air-distributing flap (9) for directing the fan's air stream onto a vaporizer (4) or a supplementary heater (5). |
