Kind Code:
B1
Abstract:
A combined air-supplying/air-purifying breathing system that includes a self- contained breathing apparatus, a facepiece for delivering breathable air from the self- contained breathing apparatus to a user, and a powered air-purifying respirator having at least one filter and a blower and having an output connected by a hose assembly to the facepiece. A control interface operationally connects the self-contained breathing apparatus to the powered air-purifying respirator. The self-contained breathing apparatus includes a pressure vessel, a cylinder valve assembly and a pressure reducer, all carried by a back frame, and the powered air-purifying respirator is adapted to be mounted on, and carried by the back frame, by coupling the back frame and the respirator together at respective attachment points.
