<p>A first stage pressure regulator (10) is provided for use with a high pressure source (20) of breathable gas. It includes housing (12) and either a yoke (14) 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 pressure-regulated outlets (32, 34, 36, 38) 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 (134, 136), a system is provided which has enhanced safety features.</p> |
