The compressor stages, which are located on sides of the compressor blocks, are the key to optimum smooth running and high efficiency.

The free-standing cylinders are easy to access and maintain. They are ideally positioned in the cooling air flow. The generous dimensioning of all bearings enables the blocks to achieve a service life in excess of 30,000 hours.

The bearings are characterised by low heat generation, low friction values and low power losses.

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.
