SCUBAPRO’s flagship reg system is designed for divers who want the best. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The A700 offers effortless inhalation and an ease of exhalation that is unmatched in a precision-handcrafted, full-metal package. Together they provide unparalleled breathing performance in all water temperatures.
First Stage
-
Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow un- affected 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 com- promising 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 3364psi/232bar INT configuration.
-
Weight: INT 232 (oz/g): 27.9/790.
-
Airflow at 2900psi/200bar: (l/min/ SCFM): >8500/301.
-
Intermediate pressure (psi/bar): 130-142/9.0-9.8.
Second Stage
• 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 with- stand 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 Ven- turi-Initiated Vacuum Assist (VIVA) lever.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouth- piece is easy to grip
yet doesn’t inhibit airflow.
• Weight: 9.3oz/265g.
• Airflow at 2900psi/200bar: 2000 l/min - 71 SCFM.
• Maximum low pressure: 203psi/14bar.
