This package does not contain the hose linking the 1st and 2nd Stage
This is the regulator of choice for any demanding diver looking for a first stage regulator that is compatible with 100% Oxygen out of the box. Outstanding performance and certified to 656' (200 meters)! The Xstreme second stage is a high-flow design providing 76 standard cubic feet per minute (SCFM) flow of gas (2,150 liters per minute). The 2nd stage regulator uses an upstream servo-valve design with a safety valve opening pressure of 261 /- 14 psi (18 /- 1 bar) relief pressure. The second stage has a durable PVC housing with metal mechanism and rubber parts. The regulator has an automatic Venturi assist and inhalation control.
The first stage is a balanced rolling diaphragm ball valve design producing extreme leak tightness. Conventional designs are sensitive to war, misalignment, and manufacturing precision. A ball valve always finds its correct place. The 1st stage construction requires less O-rings than any other regulator. The hose routing is developed to be optimized for a redundant system, using two-regulators. The HP ports are positioned to accommodate the use of gas monitoring computers e.g. first stage mounted HP sender/receive unit.
The 1st stage has a built-in Poseidon T.D.A, Thermo-Dynamic Anti-Freeze, which requires no maintenance. It is always there, doing the job. It is thermodynamically-protecting the parts which must not freeze. It is identified by the large slots in the cover, allowing the heat energy of the water to reach the spring. The Cold from the inside is consequently insulated from the spring, via an insulation barrier and insulating diaphragm. It is constructed without compromise to any detail to prevent cold reaching the sensitive area. Using Poseidon T.D.A, a regulator can free-flow air in fresh water of 32½F (0½C) for at least 10 minutes and afterwards still be completely unaffected. The 1st stage regulator is manufactured from chrome plated brass. First stage regulator has a green DIN hand wheel for easy identification of O2 use only.
