The main features of 4930255491 is small size, compact structure, no moving parts and easy installation. Its main function is to use the difference in density between oil and gas to separate the oil, gas, water and other components in the mixture under low-pressure conditions to prevent cavitation, gas lock and other faults, and improve equipment operation efficiency and reliability. It is separating the oil from compressor air filter parts, make the compressed air cleaner, and keep oil clean to return back oil tank.

4930255491 is made of ultra-fine glass fiber composite filter material produced by HV and Lydall in the United States. Under normal operating conditions, compressed air oil mist particles can be controlled to below 0.1μm. At rated operating pressure and rated flow, the initial saturation pressure drop is no more than 0.02MPa. Under normal operating conditions, with a pressure drop no more than 0.1MPa, the oil-gas separator has a service life of no less than 4000 hours.
