Technical Information
MK25 EVO DEEP BLUE First Stage:
- Jewel colored Deep Blue PVD exterior finish provides superior scratch and corrosion resistance.
- Air-balanced flow-through piston design delivers 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 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 you to position the first stage pointing up or down. This enables you to run gauges on the right or left side, plus it increases the freedom of movement for head and neck.
- Five high-flow low pressure ports on a swivel turret maximize hose routing options. High flow ports deliver about 15 percent more air than conventional ports.
- External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily without the need for disassembly.
- Available in a 3364psi/232bar INT configuration.
- Weight: INT 232 (oz/g): 27.9/790.
- Airflow at 2900psi (l/min/SCFM): >8500/301.
- Intermediate pressure (psi/bar): 130-142/9-9.8.
S600 DEEP BLUE TITANIUM CORE Second Stage:
- Jewel colored Deep Blue PVD exterior finish provides superior scratch and corrosion resistance.
- Precision molded carbon fiber and technopolymer housing is lightweight and offers cold-water and corrosion resistance for long life.
- A full titanium interior barrel makes second stage super lightweight and resistant to corrosion.
- Full metal valve housing is able to withstand years of aggressive diving.
- Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
- User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
- Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
- Weight: 6.2oz/175g.
- Airflow at 2900psi: 1850 l/min – 66 SCFM.
- Maximum low pressure: 203psi/14bar.
