Description:Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
The new MK17 EVO is SCUBAPRO's premium high performance balanced diaphragm first stage.
Engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism.
This new version is more compact than its predecessor yet delivers better breathing performance. Its improved internal design allows more airflow from the LP ports which have also been configured for optimum hose routing.
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.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
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.
Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
Rugged full metal case, front cover and valve housing are able to withstand years of aggressive diving.
Metal construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
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: 9.3oz/265g.
Airflow at 2900psi/200bar: 2000 l/ min - 71 SCFM.
Maximum low pressure: 203psi/14bar.
