M-type CNG compressor adopts four rows of symmetrical balance structure, four rows of crank 90° each other, reciprocating inertia force fully balanced, stable operation of the unit, small vibration. The machine has compact structure and easy maintenance. Especially suitable for the integration of large capacity compressors in large CNG mother station, which requires five stages of compression.
