The invention relates to a compressed air supply device for a rail vehicle, comprising a main compressor (1) for generating compressed air for a pneumatic brake system and a vehicle battery (6) for supplying electric energy. Said compressed air generating means for supplying additional auxiliary air for operating at least one pneumatic actuator (4) is provided in a frame of an adjusting drive for a pantograph (5). Said compressed air generating means for supplying auxiliary air comprises an electric frequency converter (7) for operating the electric-motor driven main compressor (1) of the rail vehicle with low rotational speed from the electric drive energy provided by the vehicle battery (6). A secondary line (9) is attached to the compressed air line (8) connected to the main compressor (1) in order to branch off the auxiliary air for the supply of auxiliary air of the actuator (4).
