A700 2nd Stage

In the second stage, the 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 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. The ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow. Airflow at 200bar: 2000 l/min

Features: 

• Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Rugged full metal second-stage case and valve housing (barrel) are able to withstand years of aggressive diving.
• Metal second-stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• Air-balanced second-stage valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Sectional exhaust tee and a first-rate purge help to deliver effortless inhalation and an ease of exhalation that is unmatched.
