Maximum Reliability for Oxygen and Technical Diving The Poseidon Xstream Duration First Stage Regulator is engineered for technical, military, public safety, commercial, and oxygen-compatible diving applications where reliability is essential. Its balanced diaphragm design, patented ruby ball valve technology, and Thermo Dynamic Antifreeze (TDA) protection provide exceptionally smooth breathing and dependable performance in demanding environments. The Duration model is oxygen-cleaned from the factory and designed for advanced technical diving systems. Available from U.S. Water Rescue, an authorized Poseidon dealer and certified Poseidon service center. Designed with one objective: to create one of the most reliable first stage regulators in the world.A patented ruby ball seal is automatically positioned by the floating seat which balances any upstream pressure equally with the pressure adjustment spring, maintaining the benefits of having a perfect ball as the sealing element without the risks that follow with incorrect sealing pressures. This makes the Xstream Range self-balancing, giving the same high performance, irrespective of the pressure in the cylinder. The Xstream range also incorporates Thermo Dynamic Antifreeze (TDA) protection into its design. The TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms.Oxygen-Clean and Approved: O1 - Oxygen engineered O2 - Oxygen compatible materials O3 - Cleaned for oxygen use\ O4 - Oxygen approved Technical Specifications: Approved for use with 99.95% oxygen DIN G5/8" connection Five LP ports Two HP ports Weight: 750 g Chrome-plated brass construction
