Compressed air conditioning unit and method for manufacturing same

The compressed air processing system (10) has a compressed air inlet (12) and an air drier cartridge (14), which is coupled with the compressed air inlet through a compressed air feed pipe (16). An outlet valve (18) is arranged in a vent line (22) branching out at a branching point (20) from a compressed air feed pipe. A filter element (24) is arranged in the vent line partially between the branching point and the outlet valve. An independent claim is also included for a method for manufacturing a compressed air processing system for a vehicle, particularly a commercial vehicle.
