Abstract

A combined air-supplying / air-purifying breathing system 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.

Description

[0001] Cross References to Related Applications [0002] This application is entitled to and claims U.S. Patent Application No. 11 / 100,051, filed April 6, 2005, entitled "Combined Air-Supplying / Air-Purifying System," and filed April 6, 2004, entitled "Combined Air- Supplied / Air-Purifying System,” U.S. Provisional Patent Application No. 60 / 560,401, the entire subject matter of both applications is hereby incorporated by reference. technical field [0003] The present invention relates generally to breathing or respirator devices, and in particular to modular combination air supply / air purifying devices comprising self-contained breathing devices and air purifying respirators that may operate independently or in conjunction with one another. Background technique [0004] Various devices are known for providing breathable air in hazardous environments. Two specific common types are the air filtration type, in which the ambient air is filtered to remove hazardous pollutants so...
