The MK25 EVO/S270 Nitrox is ideal for technical divers who need a dedicated nitrox delivery system that is certified for air mixes up to 100% oxygen. The air-balanced S270, with its PU green cover devoted specifically to this nitrox version, provides smooth and consistent airflow in a bulletproof anti-scratch design that?s able to stand up to years of rugged use. Complying with the most stringent safety norms, you simply won?t find a more reliable nitrox breathing system for all diving conditions and water temperatures than this regulator combo.

Features:

• Lightweight S270 casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improves diving comfort

• Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can't grab onto when diving in extreme cold water.

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.

• Dive/predive switch is easy to use even wearing thick gloves.

• Compact and efficient exhaust tee minimises exhalation effort

• Air balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.

• Patented XTIS (Extended Thermal Insulating system) insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.

• 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 maximise hose routing options.

• All Nitrox certified SCUBAPRO regulators are suitable for use with air mixes up to 100% oxygen.
