Compressed air filters serve to remove solid and liquid impurities (condensation water, pipe scaling, rust particles) fromthe air in the working place. They protect the following components from dirt and abrasion. This filter has beendeveloped specially for high-demanding applications. Filter with bowl without sight glass, completely made ofstainless steel, therefore extremely robust. Suitable for compressed air, non-toxic gases and liquids.Application area: Chemical industry, mineral oil processing, apparatus engineering.

Pressure regulator Type 691 – G1/4 - G1

4

The system pressure in a compressed air system varies according to the compressor size. Pressure regulatorsare reducing this fluctuating line pressure (pressure p1) to the desired working pressure (outlet pressure p2) andmaintain it largely constant. This pressure regulator has been developed specially for high-demanding appli-cations. Operating pressure from 0,1 to 15 bar. The pressure gauge can be mountet on both sides Note: Toprevent the system from dirt or breakdown, a filter should be installed at first step.Application area: Chemical industry, mineral oil processing, apparatus engineering.
