Rotary screw compressors supply production processes in industry, trade and workshop applications with a reliable supply of quality compressed air. They are the preferred choice for users requiring constant pressure over prolonged periods.

To ensure that HPC KAESER rotary screw compressors operate as efficiently as possible, KAESER developed its own special rotor profile. SIGMA profile rotors provide you with energy savings of up to 15% compared with conventional rotor profile designs.

Furthermore, HPC KAESER airends with SIGMA profile rotors boast an exceptionally long service life. This is in no small part due to the special roller bearings that are precision adjusted and generously sized. Combine this with in-house high-end manufacturing processes with lowest possible manufacturing tolerances and you have an exceptional product.
