The ST1 is a beautifully machined Stainless Steel regulator with outstanding corrosion resistance and high performance breathing. Made of a special grade of 316 Stainless Steel, the ST1 offers superior corrosion resistance for dependability while preserving our precious environment. The ST1 is fitted with our patented Atomic Aquatics Stainless Steel comfort swivel hose.
The second stage has a fantastic stainless steel 360-degree swivel which ensures the regulator is always in the right place reducing jaw fatigue and making your dive more comfortable for longer.
Like all Atomic second stages it also features the patented “AFC” Automatic Flow Control that eliminates the need for an external pre-dive switch and automatically adjusts with depth to ensure your regulator doesn’t free flow. Another unique Atomic second stage patent is the “seat saving orifice” that allows for the seat to pull away from the sealing knife edge when not in use, significantly reducing the wear on this important component and therefore increasing longevity of the regulator’s performance.
WHY STAINLESS STEEL AND TITANIUM
Stainless Steel delivers virtually the same corrosion resistance as Titanium at a lower price. Stainless Steel does not require protective chrome or nickel plating processes that can be harmful to the environment and is 100% recyclable. The ST1 second stage features all-Titanium components as in the T2 and B2 models.
