AIRCENTER screw compressor packages


A complete system

Kaeser AIRCENTERS are the answer to many challenges. The integrated design reduces time spent planning and purchasing your air system. We combine the reliability, energy efficiency, and easy-to-service design of our industrial rotary screw compressors into a space-saving package complete with storage tank and air treatment equipment. AIRCENTERS arrive completely assembled, saving you a lot of time and expense.

AIRCENTERS are available in simplex (one compressor) configurations from 3 hp units to 20 hp units.  They also offer backup capability.

  • 3 to 20 hp
  • Pressure: 125, 160, or 217 psig
  • Flow rate range: 9 – 90 cfm

AIRCENTERS require little space and are the perfect solution for smaller industrial operations.

Your advantages

  • Space-saving integrated solution:
    Compressor, refrigerated dryer, and air receiver tank in one compact package
  • Protection from corrosion damage:
    Thanks to the integrated refrigerated dryer, the system delivers high air quality and protects your equipment from corrosion damage.
  • Fast installation:
    Simply connect to the power supply and compressed air distribution network—no need to worry about major piping or installation work.
Low life cycle costs
Life-cycle costs

Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and the latest in technology to keep performance high well into the future.
