Provided with a downstream valve and an airflow channel based on the Venturi effect: air supply is steadily controlled by the diver; normal breathing means light airflow, whereas heavier breathing resulting from tiring dives, requires more air to be supplied (Venturi effect).
This system means low air consumption and reducing air wastes, as it fully satisfies breathing requirements; in addition, it provides maximum safety, as it can also work in case of first stage overpressure, releasing any excess air and translating into regular breathing.
