Description
MK17 EVO First Stage:
- Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
- More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
- Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
- Substantial increase in airflow — 6900 l/min versus 6500 l/min – includes improved balance of air supply pressure.
- Two high pressure and four high-flow ports maximize air delivery and hose routing options.
- High-flow performance is available from all four LP ports which are configured for optimum hose routing.
- Available in a 3364psi/232bar INT configuration.
- Weight: INT 232 – 30oz/850g.
- Airflow at 2900psi/200bar: 6900 l/ min – 230 SCFM.
- Intermediate pressure (psi/bar): 130-142/9.0-9.8.
S600 Second Stage
- Air balanced valve
- Diver-adjustable inhalation effort
- Diver-adjustable Venturi-Initiated Vacuum Assist (VIVA)
- Super-flow hose
- High comfort orthodontic mouthpiece
- Full metal valve housing
- Weight: 193g / 6.8oz
- Air flow at 200 bar: 1850 l/min – 66 SCFM
- Maximum low pressure: 14 bar / 203 psi
R195 Octopus
- Classic downstream valve comes with a VIVA switch to control free flows.
- Metal valve housing is built rugged and increases overall reliability.
- Yellow super-flow hose is 39 inches long and features an oversized bore 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.
