Breathing Air system is specifically designed for applications where high quality breathing air and monitoring of breathing air supply are needed. It is a combination of breathing air filter set combined with gas concentration analyzers, fitted with pressure regulator and quick couplings, all packed in a compact and robust casing. Gas concentration analyzers constantly monitor CO, CO2 and O2 concentrations and trigger an alarm if concentrations exceed the EN12021 and BS4275:1997 standard-compliant values. In this way, the unit can safely provide high quality breathing air for up to 5 people. Small dimensions and low weight enable the use of breathing air in many applications as it can be transported and set up with ease.
