The new standard of the 50 cubic meter class

The mobile compressor with a flow rate of up to 45.8 m³/ min , M500-2, combines the advantages of an oil-free two-stage rotary screw compressor with those of a mobile unit: maximum compressed air capacity and unmatched flexibility.

  • Compressed air after-cooler mounted as standard;
  • Fleet management via GPS as standard equipment;
  • Refinery equipment as standard - including certified spark arrester, engine shut-off valve and sealed floor pan;
  • Many elements to facilitate the configuration (chassis with parking brake, forklift pockets, crane and rigging eyelets.

For industrial equipment with high compressed air consumption, M500-2 ensures continuity of compressed air supply even during maintenance work. Other areas of use include refineries - for example, for flushing pipelines. This type of compressor easily integrates into existing stations.

Our approach guarantees high long-term yields: durable components, easy operation, efficiency and performance: all these characterize with great fidelity the machines delivered by Kaeser.
