THE BENCHMARK FOR HIGH PERFORMANCE
The Xstream features technology like non other. Taking advantage of a side purge, current-induced free flow is prevented while at the same time diverting bubbles that would otherwise obstruct the divers view. The regulator's small size keeps it out of the way while its symmetry allows use from both the left and right side.
The objective; design the most reliable first stage 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.
Added to this the range has a built-in anti-freeze protection in its construction. The TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms.
the worlds toughest
Poseidon Xstream first stage has a built in anti-freeze protection in its construction. TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms. No extra environmental sealing required.
