MK25 Evo INT
-
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) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing 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.
-
Four high-flow and one axial super 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.
