Whole Machine Description
This D-type balanced air-cooled oil-free reciprocating piston compressor features 2-row 3-stage compression with modular integrated assembly.
Gray cast iron crankcase holds lubricating oil, reserved with ports for oil filling, draining, level observation and temperature detection, fitted with external drain ball valve.
Double middle body isolates crankcase oil from cylinder to avoid medium pollution. Cylinder and cylinder head use gray cast iron or forged steel with oil-free design, axial air valves mounted on cylinder heads.
