Oil-injected rotary screw compressors

Large selection – Low life-cycle costs

Fluid-injected rotary screw compressors are used in a wide range of sectors. They are highly durable and operate reliably and efficiently even at high temperatures of up to 45 °C. The associated investment costs are comparatively low.
However, the lion‘s share of life-cycle costs is spent on energy (up to 80 %). in fact, energy costs taken over the lifetime of a compressor, add up to a multiple of investment costs. For this reason, KAESER rotary screw compressors are equipped with energy-saving SIGMA PROFILE airend rotors that save up to 15 % energy compared to conventional rotor profile designs.
