CO can enter the system via the air intake but is also produced internally when an overheated compressor burns its own oil.If using a portable compressor, be sure to have the air intake many feet, and upwind away from the exhaust, and monitor CO with a detector periodically near the intake, as well as in the tank after it is filled.
