MK25 Evo / A700

• Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patent pending XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions 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 a 232bar INT configuration.
• Weight: INT 232: 790 g.
• Airflow at 200bar: (l/min): >8500.
• Intermediate pressure (bar): 9.0-9.8.

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Rugged full-metal case, front cover and valve housing are able to withstand years of aggressive diving.
• Metal construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
• Weight (without mouthpiece): 261g.
• Airflow at 200bar: 2000 l/min.
