The new S270 is available with a MK11 first stage for divers seeking an air-balanced diaphragm design delivering effortless airflow unaffected by depth, tank pressure or breathing rate. The MK11’s chrome-plated marine-grade brass body has sealed internal parts to prevent water and pollutants from fouling the inner mechanism while enhancing cold water performance. The new air-balanced S270 provides smooth breathing performance in a bulletproof anti-scratch design that’s able to handle years of hard use. It comes with a dive/predive switch, an effective purge, and a compact  exhaust tee that minimizes exhalation effort.

MK11 EVO First Stage

  • Air-balanced diaphragm design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Marine grade brass body has sealed internal parts to prevent water and pollutants from fouling the inner mechanism while enhancing cold-water performance.
  • Two high pressure ports, two standard low pressure ports and two high-flow low pressure ports maximize hose routing options.
  • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
  • Weight (oz/g): INT 232, 30.3/860; DIN 300, 22.6/640.
  • Airflow at 2900psi/200bar: (l/min/SCFM): >5500/195.
  • Intermediate pressure (psi/bar): 133-142/9.2-9.8.

S270 Second Stage

  • Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
  • Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can’t grab onto when diving in extreme cold water.
  • Dive/predive switch is easy to use even wearing thick gloves.
  • More compact, lighter weight and better breathing performance than its S560 predecessor.
  • Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort.
  • The exhaust tee is compact and very efficient in minimizing exhalation effort.
  • Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone, and features a large cross-section to maximize airflow.
  • Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
  • CE certified to the latest EN250A European Standards for all diving conditions, including extreme cold water.
  • Well-suited for diving classes, rental and professional accounts due to its bulletproof construction and solid breathing performance.
  • Weight (without mouthpiece): 5.1oz/145g.
  • Airflow at 2900psi/200bar: 1850 l/min – 66 SCFM.
