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.
