Depending on the model, the compressor blocks in the new K 22 series feature 2 to 5 compressor stages for final pressure levels up to 525 bar.

With their outstanding surface hardness, plasma-nitrided and plateau-honed cylinders are able to achieve extremely long service lives combined with low energy consumption and reliable oil lubrication of cylinder surfaces.

The high-pressure final stage of the compressor features a piston. The compression piston is able to move freely and is not connected to the guide piston. Lateral forces which may cause increased wear are therefore prevented.

Generously dimensioned stainless steel intercoolers and aftercoolers and intermediate and final separators can be relied upon to remove condensate and safeguard long and reliable operation.
