Atomic ST1 Swivel Sealed Diving Regulator – Atomic

Atomic ST1 Swivel Sealed Diving Regulator – Atomic

Atomic Aquatics has created another industry first: the world’s first “green” regulator!

The first stage is machined from a special 316 stainless steel, with twice the strength of brass and corrosion resistance close to titanium. Environmental specialists worldwide classify stainless steel as the “green metal” of the future. It requires no additional chrome or nickel plating processes, which can be harmful to the environment, and is 100% recyclable. The second stage features all titanium components.

High-performance breathing: low inhalation effort even at deep depths and high breathing rates, providing a natural and comfortable air supply. The entire second stage is constructed from titanium—the only one in its class with fully titanium components, offering maximum corrosion resistance and lightweight performance.

Atomic Aquatics patented “Comfort Swivel” second-stage hose. The only swivel second stage of its kind that allows one-direction movement without performance loss. It articulates with minimal movement, eliminating hose pull or jaw strain. Made from polished 316 stainless steel.

Seat-saving orifice: Atomic Aquatics’ patented feature extends the life of the second-stage seat indefinitely, eliminating leaks and performance degradation.

AFC (Automatic Flow Control): Atomic Aquatics’ exclusive feature automatically adjusts airflow at depth to maintain smooth and comfortable breathing.
