Technical Information

First Stage MK25 EVO

• 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 by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Key insulation system components are visible in blue.
• 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.
• Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximise hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Available in either 232bar INT or 300bar DIN configurations.
• DIN version comes with a dual-compound wheel that features an ergo shape and softgrip on a rugged black nylon frame.
• Airflow at 200bar: >8500 l/min
• Intermediate pressure: 9.0-9.8 bar

Second Stage A700

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Rugged full-metal case, front cover and valve housing (barrel) are able to with standyears 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.
• Airflow at 200bar: 2000 l/min
