ABSTRACT:
A first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and either a yoke arrangement for connection to the conventional U.S. high pressure gas source or a DIN connection for coupling to a European-type gas source. First and second presure-regulated outlets are provided and independently regulated in order to provide from a single high pressure source dual intermediate pressure air for delivery to second stage regulators. In combination with second stage regulators, a system is provided which has enhanced safety features.
