Air filter arrangement for vehicle air-conditioning system

摘要

In order to achieve an effective cleaning of the filter in the case of a heating or air-conditioning system of a motor vehicle without having to change the rotating direction of the fan, the fan is installed in the incoming-air flow downstream of the air filter device. Behind the fan, at least one blocking member is arranged that prevents the entrance of air from the fan to the passenger space during the cleaning phase and instead causes the conveyed air to flow out from the fan housing in the direction of the air filter device.
