DFC

The DFC system (Mares patented) minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. This phenomenon is even more pronounced as depth increases and when airflow demand from the regulator rises.
The DFC system is an exclusive system, unique on the market, that operates in relation to the diver's actual air demand, independent of depth and tank pressure.
The DFC system uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.
