Patented Anti-Frost Control

Optimal protection at low temperatures

Anti-Frost Control logo

  • Prevents breakers from freezing up
  • Extends service life of pneumatic tools
  • No manual adjustments needed

The Kaeser patented Anti-Frost Control is a combination of thermostatic valves which guarantees that the ideal operating temperature, based on the ambient temperature, is quickly reached and maintained regardless of the weather conditions. This technology has demonstrated its reliability thousands of times. It is no longer necessary to switch manually from summer to winter mode. This also eliminates the possibility of operating errors.

Drive options: diesel engine and electric motor

Compact units with diesel engines

  • Water-cooled Kubota engines
  • Quiet operation, low exhaust emissions
  • With electric fuel pump

Compact units with 400V electric motor

MOBILAIR electric portable compressors truly come into their own in work environments where quiet and exhaust-free conditions are required. These environmentally-compatible compressors therefore elegantly avoid any restrictions that may apply to the use of combustion engines. 

  • Quiet with zero on-site emissions
  • With pole-reversing switch
