1. Gas compressor is with two-stage compression, four cylinders, four throw, horizontal symmetrical balanced type. The six cranks of crankshaft are at 60 degree of each other and in uniform arrangement, each two cranks in one group are at 180 degree, which make rotational inertial force and primary inertial force into self-balance. Uniform distribution of Piston force, small vibration, stable running, high reliability, longest lifetime of wearing parts.

2.Speed 375rpm, rated piston force 320KN, shaft power2800KW.
