The crankshaft assembly is linked to pistons of the first and second piston cylinders by respective connecting rods. The connecting rods connect to a wrist pin associated with each of the pistons, and the wrist pins are respectively supported by a dry lubricant bushing to the associated piston. The compressor housing may have at least a first housing portion and a second housing portion. The first housing portion and the second housing portion may form respective halves of the compressor housing that are secured together with mechanical fasteners.
