    Operating principle Operating principle Operating principle Operating principle Operating principle The refill stations in the “Compact” series are of the semi-soundproofed type (model MCH 13-16/ET) (Fig. 2) (model MCH 26-32/ET) (Fig. 1). Model MCH 13-16/ET is fitted with a compressor (Fig.

  • Page 11: Description Of The Pump Unit

    The intake air contains a certain degree of humidity according to atmospheric conditions. During the compression and subsequent cooling, the humidity condenses and together with the particles of lubricating oil forms a milky white emulsion that precipitates into the separators. The compression diagram is included in chapter 13.
