Atomic ST1 Regulator

The first “Green” regulator ever designed, the Atomic ST1 Regulator is made of a special grade of 316 Stainless Steel that is 100% recyclable. The ST1 offers superior corrosion resistance and does not require Chrome or Nickel-plating processes that create environmental concerns.

ST1 Stainless Steel & Titanium Regulator

At Atomic, it’s all about the metals. The 316 Stainless Steel used in the Atomic ST1 Regulator has twice the strength of brass with the durability of Titanium. It delivers virtually the same corrosion resistance as Titanium at a lower price.

Environmental experts have classified Stainless Steel as the Green metal of the future because of its strength, ability to resist corrosion and ability to be recycled.

The Atomic ST1 Regulator is designed to breathe effortlessly at atmospheres below the surface while helping preserve the atmosphere above.

Titanium Second Stage components

While the first stage is a beautiful, bright-turned machine finish that will last a lifetime, the ST1 is corrosion-resistant inside and out. The same Titanium second stage components used in the T3 are used in the ST1.

Easy breathing is delivered by the patented Titanium Seat Saving Dynamic Orifice and balanced poppet, case and lever design. The ST1 is Nitrox-ready up to 40%.

Comfort Swivel

The ST1 second stage offers the same renowned Atomic designs as the T3, including the patented AFC Automatic Flow Control with Rapid Adjustment Knob. A Stainless Steel Comfort Swivel hose allows a 30°effortless range of motion without pulling or binding.

Environmentally conscious topside natural breathing at depth

The Atomic ST1 Regulator is another industry first from Atomic Aquatics. The first stage is beautifully machined from a special grade 316 Stainless Steel that is twice the strength of brass with corrosion-resistance approaching Titanium.

The use of Stainless Steel means Atomic is doing its part for clean air when divers are out of the water. The legendary Atomic design means divers also breathe easily at depth.

Jet Seat Piston

The Atomic Jet Seat system has no sharp edges that can damage the seat over time. Instead, Atomic employs a conical seat and blunt-end piston.

Atomic valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.
