Quiet air compressor with space-saving design

AIRCENTER SERIES COMPRESSORS

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 quiet, 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) and duplex (two compressors) configurations from single 5 hp units to twin 20 hp units. Duplex models offer added energy efficiency by running only the compressor(s) needed to meet the current demand. 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. With noise levels as quiet as 61 dB(A) you can install it anywhere without disrupting productivity.

Your advantages

  • Space-saving integrated solution:
    Compressor, refrigerated dryer, and air receiver tank in one quiet, air compressor 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 a global service and consulting network with fast response times.
