Section II. DESCRIPTION AND DATA
3. Description
a. General Information. The Le Roi truck-mounted air compressor Model 210G1 (fig. 1) is a self-contained unit
complete with all controls, switches and indicators necessary for normal operation. The engine-compressor is completely
inclosed in a sheet metal housing (fig. 2). Doors in the housing (fig. 1) provide access to all parts of the engine,
compressor, and instrument panel. A weather cap mounted on the engine exhaust pipe prevents the entrance of moisture
into the engine. The basic engine-compressor is set in a steel frame with neoprene vibration dampers to alleviate
vibrations. The entire unit is mounted on a 2 1/2-ton, 6 x 6 truck. Hose reels (fig. 3), valves, and instruction plates are
located at the rear of the compressor.
