1. An air compressor system, comprising:
a housing;
a piston having a connecting rod arranged in the housing, wherein the piston is hollow and comprises an interior space within the piston into which air entering the air compressor system flows, wherein the interior space extends through a first portion, a transition portion, and a second portion of the piston, and wherein air exits the interior space through a piston crown of the first portion; and
a crankshaft arranged in the housing, the crankshaft coupled to the connecting rod of the piston, and the crankshaft is configured to force the piston to oscillate from a first end of the housing to a second end, the piston pressurizing air in the housing to a first pressure at the first end and to a second pressure at the second end, the second pressure greater than the first.
