D420 2nd Stage

  • NEW. Uniquely shaped fibreglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology.
  • NEW. Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface.
  • NEW. Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve.
  • NEW. Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
  • NEW. Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier.
  • Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility.
  • Large purge button is easy to reach and press, with or without gloves.
  • Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation.
  • Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
  • Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
  • CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.
  • Weight (without mouthpiece): 216g.
  • Airflow at 200bar: 1800 l/min - 64 SCFM.

Combined with the superb MK25 Evo

Technical Information

MK25 EVO 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.
  • Patent-pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous  MK25 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 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • 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.
