Compact, efficient, and oil-free

The SKL LS oil-free screw compressor series is specially designed for mobile use on silo trailers as well as for stationary unloading systems. Wherever compact design, high efficiency, and oil-free compressed air are essential, the SKL 700–1100 LS delivers reliable performance.

Covering a volume flow range of 385 to 1,050 m³/h, these compressors are engineered to meet a wide variety of flow requirements. With input speeds from 652 to 1,800 rpm, both the SKL700 and SKL1100 models offer exceptional flexibility for integration into various PTO systems.

The custom-developed rotor profile ensures:

High efficiency
Low noise emissions
Minimized discharge temperature of the compressed air

This makes the SKL LS series ideal for transporting sensitive bulk materials, including food, plastic pellets, and hygroscopic substances.
