  • Capacities from 9 to 3044 cfm

Integrated Systems

Kaeser’s rotary screw air compressors are also available in a variety of different configurations. These packaged systems can be customized to suit your specific compressed air and clean air treatment needs.

The three most popular types are as follows:

Sigma Frequency Control

Kaeser’s Sigma Frequency Control (SFC) combines Siemens AG drive technology with their Sigma Profile airend and Sigma Control system. Their engineers have optimized airend design to accommodate a wide flow range with unmatched efficiency. Kaeser’s SFC units range from 8 to 515 kW and are incredibly quiet, with noise levels as low as 67 dB(A). SFC models up to 132 kW are also available with integrated dryers.

“T” Series

While all Kaeser compressors are available as stand alone units, most models can also be ordered with clean air treatment built in. The “T” series rotary screw compressors have integral refrigerated dryers with stainless steel, plate-type heat exchangers, moisture separators, and condensate drains. These all combine to remove moisture and contaminants from your air system to improve product quality and reduce wear on equipment.


To help with your space limitations and to save on installation time, Kaeser offers its AirCenters. These are complete air systems that include not only the dryer but the air receiver tank too. Available with either one (simplex) or two (duplex) Sigma rotary screw compressors, they come pre-assembled with a refrigerated air dryer mounted on a horizontal receiver tank. Kaeser has a wide range of models available, from 5 to 40 hp, and these units are perfect for small shops or plants.
