Scubapro MK17 EVO 1st stage

- Air balanced diaphragm first stage, with its chrome-plated brass body, 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.

- 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. High-flow performance is available from all four LP ports which are configured for optimum hose routing.
