An air supply system having a multi-cylinder, two-stage air compressor including a pair of low pressure cylinders and a high pressure cylinder. A first intercooler interconnected between the outlet of one of the pair of low pressure cylinders and the inlet of the high pressure cylinder and a second intercooler interconnected between the outlet of the other of the pair of low pressure cylinders. An aftercooler connected to the outlet of the high pressure cylinder for effectively reducing the temperature of the compressed air supplied to a storage reservoir to near or at ambient temperature. A protective housing including a frontal screened opening for permitting a rotary fan to draw cooling air into the housing and including an internal shroud for directing the cooling air over the intercoolers and aftercooler.
