Abstract: There is disclosed a compressed air delivery system for delivering clean, dry, compressed air from a source of compressed air to a compressed air appliance. The compressed air delivery system includes a vertical, cylindrical tank with an inlet located in the lower 1/3 of the tank and an outlet located near the top of the tank so that the air in the tank becomes stratified with the light, clean air at the top. The inlet to the tank includes in series a connector connected to a source of compressed air, a stepdown regulator, a check valve, an inlet port, and an inlet tube filled with packing material. The outlet of the tank includes in series a drop tube inside the tank, an outlet port, a shut off valve, a particulate filter, a coalescing filter, a stepdown regulator, and an output coupler.
