Airstream First Stage PVD black

The Airstream Overbalanced and Environmentally Sealed first stages are manufactured through a forging process that allows for optimized hose routing. The low-pressure ports are angled 30 degrees downward and 23 degrees outward to allow the hose to pass directly over the shoulders. The high-pressure ports are angled 45 degrees downward to keep the gauges closer to the diver's waist and body. This process also allows airflow to pass through larger passages. Combined with the overbalanced diaphragm, this achieves the lowest work of breathing (WOB) of 0.80 joules per liter in all conditions and temperatures. A forged heat transfer is built into the front of the Airstream body to keep warmer air in and push cold air out, allowing this regulator to operate in the coldest conditions where others fail.
