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.
