Air treatment

Cool, clean compressed air

Compressed air treatment

  • The compressed air is cooled to 45°F above ambient temperature.
  • With the compressed air cooler installed at an angle, the accumulated condensate is easily drained away.
  • The hot exhaust gasses from the motor are also used to aid condensate evaporation. This prevents condensate accumulation from causing the cooler to freeze up.
  • The microfilter provides additional oil filtration to ensure a high quality of compressed air. The included differential pressure gauge lets you see the filter's status at a glance.
Additional air treatment components should be installed downstream of the aftercooler and centrifugal separator  in order to achieve a specified compressed air quality class.

Stationary portable compressors: M58 Utility

Standalone, space-saving source of compressed air

M 58 utility portable compressor from Kaeser Kompressoren

  • With their compact footprint, these units are perfectly suited for installing on a truck cargo bed or anywhere on a construction site where a reliable source of quality compressed air is required.
  • In addition, smart features like the fixed lifting eye and the skid mounting with fork-lift pockets make the machine very easy to transport.
  • Refueling, oil changes, and other maintenance tasks are simple with convenient component access from the side.
  • The exhaust is directed upward. The M58 Utility is equipped with a built-in diesel fine particulate filter for low emission zones as standard (in compliance with Tier 4).

Patented Anti-Frost Control

Anti-Frost Control logo

For models without a compressed air aftercooler, Kaeser’s patented Anti-Frost Control automatically adjusts the operating temperature in relation to the ambient temperature. This extends the uptime and service life of both the compressor and the tools.
