Abstract
Air compressor systems that are configured to output compressed air. Each system includes a cabinet and at least one air compressor mounted at least partially in the cabinet. The air compressor includes a drive motor with a cooling air inlet through which cooling air can be input for cooling the drive motor. The cooling air inlet is directly fluidly connected to a cooling air opening of the cabinet so that the cooling air for the drive motor is drawn into the drive motor directly from the ambient environment instead of being drawn in from the interior space of the cabinet. In addition, the system includes an exhaust fan on the cabinet that vents the interior space of the cabinet to the ambient environment. During operation of the air compressor, a negative cabinet pressure is created in the interior space where the pressure is less than ambient pressure.
