Technical Information A700 CARBON BLACK TECH Second Stage: Hand-made carbon fiber front cover, metal casing and metal valve housing make for a rugged second stage able to withstand years of aggressive diving. Carbon fiber is virtually bulletproof and also extremely lightweight. The A700 Carbon’s cover weighs only 10 grams, compared to the 42-gram weight of the original A700’s metal cover, resulting in more comfortable diving. DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator. Special Torx cover screws are able to support a higher tightening torque without damage. Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity. Air-balancing smoothes out the inhalation effort when diving at varying depths and supply pressures. User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch. 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. Weight: 8.2oz/233g. Airflow at 2900psi/200bar: 2000 l/ min – 71 SCFM. Maximum low pressure: 203psi/14bar. MK25 EVO BLACK TECH First Stage: Air balanced flow-through piston in a Black Tech-coated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate. DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator. 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 compromising 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 either a 3364psi/232bar INT or 4350psi/300bar DIN configurations. DIN version comes with a new dual-compound wheel that features a new ergo shape and soft grip on a rugged black nylon frame. Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572. Airflow at 2900psi/200bar: (l/min/ SCFM): >8500/301. Intermediate pressure (psi/bar): 130-142/9.0-9.8. SKU: 12.770.700. Category: Regulator.
