The latter can operate at negative pressure or at p

42、ositive pressure and is connected to a suitable full face mask, possibly via a breathing hose. A compressed air supply tube connects the wearer to a supply of compressed air. Exhaled air flows into the ambient atmosphere via an exhalation valve.NOTE Conformance to EN 12021 can be ensured by a breath
