About Poseidon Atmosphere Mask M Complete

The Poseidon Atmosphere Full-Face Mask M with the Poseidon Jet-Stream Second Stage Regulator is the choice for professional and cold-water diving. The perfectly fitting Atmosphere Full-Face Mask protects your face from the cold. Mask can have communication equipment install to talk with your buddy during dives. As an overpressure mask it also allows you to dive contaminated water without getting dirty water on your face. Mask is equipped with a highly effective defogging system and has an anti¬-distortion visor.

The Jet-Stream Second Stage is a high-flow design providing 63 standard cubic feet per minute (SCFM) flow of gas (1,800 liters per minute). The 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. 2'nd stage comes with a 27.5" (70 cm) low-pressure hose.

The first stage is a balanced rolling diaphragm ball valve design producing extreme leak tightness. Conventional designs are sensitive to wear, misalignment, and manufacturing precision. A ball valve always finds its correct place. Combined with the 2'nd stage, the enormous capacity of the 1'st stage make the regulator meet the EN 250 breathing performance requirements even at as low as 232 psi (16 bars) cylinder pressure. This means that you gain an extra 493 psi (34 bars) of gas compared to most other regulators! The 1'st 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 1'st 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 32ºF (0ºC) for at least 10 minutes and afterwards still be completely unaffected. The first stage regulator is manufactured from chrome plated brass.

The Atmosphere Mask M and head strap is manufactured from black silicone with a polycarbonate visor. The head strap is a fully adjustable 5-point spider and the mask has a double feathered edge seal. The head strap and feathered edge seal combine for a perfect fit on the face. The visor is frosted to avoid distortion and reflections. The Atmosphere Mask M with 2'nd Stage Regulator comes with an owner's manual.
