3 - 700 hp industrial air compressors

Rotary screw compressors with quality you can count on

Industrial rotary screw air compressors power production processes with a reliable supply of quality compressed air in countless industrial, trade, and workshop applications. They are the preferred choice for users requiring constant pressure for extended periods of time.

To ensure that our screw compressors operate as efficiently as possible, we developed our own special rotor profile. Our SIGMA profile rotors provide energy savings of up to 15% compared to other conventional rotor profile designs. 

Our precision-machined and generously sized roller bearings help give our SIGMA profile airends an exceptionally long service life. All of this, combined with our state-of-the art in-house manufacturing processes and strict manufacturing tolerances deliver the exceptional level of quality synonymous with the KAESER name.
