Description of the range


Compressed air energy saver!

For years, the AIR-SAVER has helped end-users save valuable compressed air by not unnecessarily reducing compressor operating hours and thus extending compressor life, saving energy and operating costs.

The AIR-SAVER-LS G2 (light switch) is installed in the compressed air system after the air receiver. The AIR-SAVER-LS G2 is controlled via an internal relay which is connected to an external switch and a separate power supply. A typical installation example is to connect the AIR-SAVER-LS to a light switch.

By switching on the lights in the production area – the AIR-SAVER-LS will then open. The compressed air saved flows into the factory compressed air network and the compressor starts producing the air needed to fill the system.

At the end of the working period, switch off the light(s) and the AIR-SAVER-LS will close accordingly. This version allows you to define the open and closed position according to specific customer requirements. For further information, please consult
