Greenfield – Type DM

The DM compressor range utilizes GREENFIELD’s revolutionary oilfree high-pressure technology, which assures that oil neither contaminates the gas nor does oil disposal contaminate the environment. The hermetically sealed compressor-motor-unit with mangetic coupling ensures no gas losses to atmosphere. Due to the scotch yoke drive and antivibration pads the DM has a low vibration and noise level. The vertical arrangement allows an installation in an area of 0.7 m2.

As the design for 2, 3, 4 or 5 stage units remains the same, the compressor blocks can be easily exchanged if suction pressure conditions or location of the installation changes.
