22 Navy II First Stage
The 22 Navy II first stage is highly reliable even under extreme diving conditions. Equipped with high flow rate, pre-oriented DFC outlets. The regulator comes with a special kit for dives in especially cold water. This first stage is approved by the US Navy since it has passed the high standards required by the US Naval Forces. It was specifically tested on extreme dives (30 minutes duration, 60m depth, 62.5 l/min ventilation, -2°C water temperature, 6-minute ascent in both fresh and salt water, constant cylinder pressure of 170bar).
