Technical Information:

MK11 First Stage:

  • Air balanced diaphragm design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Marine brass body has internal parts that are sealed to prevent water and pollutants from fouling the inner mechanism while enhancing cold-water performance.
  • Two high pressure, two low pressure and two high-flow ports 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 - 24.4oz/692g; DIN 300 - 16.6oz/470g.
  • Airflow at 2900psi/200bar: 5500 l/min - 195 SCFM.
  • Intermediate pressure (psi/bar): 130-142/9.0-9.8.

R195 Second Stage:

  • Classic downstream valve comes with a VIVA switch to control free flows.
  • Metal valve housing is built rugged and increases overall reliability.
  • Super-flow hose features larger inner diameter to increase airflow.
  • Reversible hose attachment makes it easy to use on deco tanks.
  • Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
  • Weight: 7.0oz/198g.
  • Airflow at 2900psi/200bar: 1400 l/min - 50 SCFM.
  • Maximum low pressure: 203psi/14bar.
