Abstract : The engine-driven, rotary air compressor is a portable, 2-wheel, frame-mounted unit. The 2-cylinder military standard engine drives the rotary compressor through a flexible coupling. The engine is 2-cylinder, air-cooled, and gasoline-driven. It develops three horsepower at 3600 revolutions per minute. The rotary compressor is a positive displacement unit that uses two, matched, close-tolerance rotors. The rotors are ball-bearing mounted inside frames and are incased in a close-tolerance rotor housing. Air is drawn into one side of the compressor through a filter and is discharged into a manifold at the opposite side of the compressor. At atmospheric pressure, at an ambient temperature of +75 F, the compressor provides a minimum of 60 cfm of free air at 6.5 psig when driven at 3600 rpm. The test item met all of the military requirements for the capacity, use condition (drop test), tilt operation, and air-relief valve tests.
