Abstract
In a compressed air breathing apparatus, a single combined high/medium-pressure line () consisting of a medium-pressure hose and a coaxial, flexible high-pressure line inside said hose is integrated into the pressure reducer () connected to a compressed air bottle so that said line can rotate in axial direction. The free end of the combined high/medium-pressure line () can also rotate in axial direction when connected to a manifold block () for distributing the supplied high or medium-pressure air to connections for a lung machine (), a pressure gauge (), and an alarm whistle () that is controlled at high pressure and operated at medium pressure. The manifold block () is equipped with an additional high-pressure fast-fill connection () and an additional medium-pressure connection (). A compressed air breathing apparatus of this design is simple, convenient, and safe to handle.
