The air valve optimized with CAD has small resistance and long service life.Advanced shaft seal structure and materials are reliable and durable.The body machined in the high precision machining center provides a powerful guarantee for improving kinematic accuracyThe high pressure connecting rod needle bearing integrally with a cage has high precision and long service life.Monolithic casting machining technology for piston rings prevents elastic force from attenuation.Good abrasion resistance of high-phosphorus and electric firelight heat-hardened cylinder sleeveThe dynamic balancing checked crankshaft has good balance and small vibration.Connection with an elastic joint slack to realize high efficiency, energy saving, self-calibration and self-alignment function.The energy regulation mechanism enables the unit to start with no load and to run with part load, and thus saving electric power. Now MOON-TECH just produce few piston compressor, normally our customers will choice screw compressor, for old factory the piston compressors are replacing by screw, if you are really interesting on piston, please contact us.
