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.
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 low pressure ports maximise air delivery.
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.

SECOND STAGE: Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures
Metal valve housing (barrel) is able to withstand years of aggressive diving
User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch
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

Full regulator system package includes R105 Octopus.
