Abstract: A multi-stage piston compressor with a cooling arrangement is provided. The multi-stage piston compressor includes a compressor unit having a plurality of air-cooled cylinders on a crankcase housing, a motor unit that is mounted at an end face of the crankcase housing, and a cooler unit at an opposing end face of the compressor unit. An axial fan wheel of the cooler unit blows cooling air substantially outwards toward the compressor unit. In order to conduct cooling air externally in the region of said compressor unit, at least one air guide housing mounted between the cooler unit and the crankcase extends at least partially radially around the crankcase in a curved manner, such that the axial air flow generated by the axial fan wheel is at least partially guided around the crankcase in the radial direction and toward at least one cylinder at the air outlet side of the air guide housing.
