Flowcharts

Process flow, oil flow and cooling flow – step by step

The air is drawn into the compressor through the inlet filter where the air is cleaned. Next, it passes through the throttle valve with an integrated blow-off valve that takes care of the load / unload regulation. The air then continues to the compression stage.

In the first compression stage, the air pressure is raised to the intermediate pressure after which the air is cooled down in the intercooler. After the intercooler, the air passes through a moisture separation system before entering the high-pressure stage.

In the high-pressure stage, the pressure is brought to the final pressure. The air at the outlet of the high-pressure stage goes via the pulsation damper with an integrated check valve to the aftercooler where it is cooled down and moisture is separated and evacuated. The compressed air leaves the compressor through the outlet connection flange.

The yellow flow is the oil path within the compressor, where the oil pump sucks oil from the oil sump and pumps it through the oil cooler and the high-efficiency filter giving cool clean oil to the bearings, the gears, and the compressor’s element jackets. It is important to note that in the complete process, no oil comes in contact with the Air, hence ensuring complete oil-free air.
