Atlas Copco’s DM oil less reciprocating compressors are suitable for your needs for high pressure compressed air up to 447 bar(a). The compressors are compact and have a low vibration level with a sealed crankcase.
DM compressors are perfect for the compression of air, nitrogen, natural gas, processed bio-gas, hydrogen, noble gases and other industrial gases. It uses the Greenfield technology which has a worldwide reputation and is a part of the Atlas Copco Group.
It comes with a high degree of safety and uses an oil-free technology that avoids the contamination of gas caused by oil. It comes with a hermetically sealed crankcase that guarantees no emission of gases to the atmosphere along with the gases with a low molecular weight.
