Due to the 180 ° twisted, opposite arrangement of the cylinder results in a much lower vibration run recorded in the cylinders piston for compression of the gas to be compressed. Together with the rotary compressor provided in the low-pressure range, this results in an extremely compact multi-stage compressor, with which a relatively high compression of a gas to be compressed can be achieved, whereby at the same time the pressure generated by the multi-stage compressor. th vibrations are kept low. As a result, the multistage compressor according to the invention is particularly suitable for use in mobile compressor installations as well as in compressor installations mounted on a ship.

Alternatively, achieving a small span is also possible when the cylinders are double acting are formed. Due to the comparatively short span, the multi-stage compressor can advantageously be accommodated in ISO containers that are 8 ft (2.54 m) wide and either 20 ft (6,079 m) or 40 ft (12.9 m) long.
