Compressed air for industry and businesses that use compressed air as an energy source is generated by means of so-called compressed air generation systems. Compressed Air generation systems are used to drive machines in mining, for pneumatic control systems in assembly plants or tyre inflation systems at petrol stations. A key component of these systems is the compressor. It converts the supplied mechanical energy into a higher air pressure. 

The air is sucked into the intake vessel through a pressurized nozzle and calmed there before it is compressed in two stages. The additional pressure vessel for intercooling is located between the first and second stage. After the second stage, the compressed air is pressed into another To be a steady state, the compressed air can be released through a blow-off valve with silencer. Safety valves and a pressure switch complete the system.

Includes a complete compressed air generation system with a two-stage compressor and an additional pressure vessel as intercooler. The trainer enables the recording of compressor characteristics and representing the compression process in a p-V diagram. The measured values ??can be read on digital displays. The measured values ??can be read on digital displays.
