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
- 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 maximize 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
soft grip on a rugged black nylon frame - Airflow at 200bar: >8500 l/min
- Intermediate pressure: 9.2-9.8 bar
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 (barrel) 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
- Airflow at 200bar: 2000 l/min
