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 our rotary screw compressors operate as efficiently as possible, we developed our own special rotor profile. Our SIGMA profile rotors provide you with energy savings of up to 15 % compared with conventional rotor profile designs. Furthermore, our airends with SIGMA profile rotors boast an exceptionally long service life. This is in no small part due to the roller bearings we choose to use: they are precision adjusted and generously sized. Combine this with our in-house high-end manufacturing processes with lowest possible manufacturing tolerances and you have an exceptional product.
