Air Treatment N/A Cool, clean compressed air
  • 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 N/A 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. N/A
