ABSTRACT:
A fresh air supply device for a heating, ventilating and/or air-conditioning installation of a motor vehicle is provided wherein the fresh air enters through a gap between the windshield and the hood into an air collecting tank. In order to prevent the admission of moisture to an air filter and to prolong its useful life, the water flowing off the windshield and entrained by the airstream is received by a channel oriented in the transverse direction of the vehicle. This channel is followed by a grill for separating out larger particulate matter entrained in the airstream. A downward-pointing ledge adjoins the grill for further demoisturizing and to deflect the air and at least partially covers a dust filter which is arranged in such a position in the airstream that dust dropping from its dirty side falls freely downwards.
