Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. Key insulation system components are visible in blue.
New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
Two opposing high pressure ports allow the first stage to be positioned either up or down.
Five high-flow low pressure ports on a swivel turret maximize hose routing options.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
