Scubapro MK25 Evo Technical Specifications

First Stage

• 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.
• 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.
• Available in a 3364psi/232 bar INT configuration.
• Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.
• Weight: INT 232 (oz/g): 27.9/790.

Scubapro S620Ti Technical Specifications

Second Stage

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is able to withstand years of aggressive diving.
• Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
• Large diaphragm fits inside a more compact casing for maximum breathing sensitivity.
• User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
• New exhaust tee increases performance while directing bubbles out of the field of view.
• Newly designed Compact Hi-Flow mouthpiece, exclusive to the S620 Ti, is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Specific matching colors (blue, pink, yellow, purple, white and orange) on mouthpiece and hose protector are available as an accessory.
• Weight (without mouthpiece): 6.3oz/179g.
• Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM.
