Project Description


  • Reliable and robust, the O50 uses the time-proven, easy to service down-stream valve. Coupled with our high-spec, large bore intermediate pressure hose (max. service pressure @ 34.5 BAR / 500psi), it flows more than enough air even when breathing demand is high.

  • The light-action purge button is easy to access.

  • The pre-dive/ dive switch atop the second stage housing prevents free-flow while the diver is on the surface.

  • Cracking pressure setting @ 1.2 inch of water Flow rate @ 206 bar (3000psi): 30 cuft / min max. service intermediate pressure @ 10 BAR (145psi)
