Product Information

EASY AIR BELOW. CLEAN AIR TOPSIDE.

At Atomic Aquatics, it’s all about the metals. The 316 Stainless Steel used in the ST1 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 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%.

PATENTED STAINLESS STEEL COMFORT SWIVEL

The ST1 second stage offers the same renowned Atomic Aquatics designs as the T3, including the patented AFC Automatic Flow Control with Rapid Adjustment Knob. A Stainless Steel Comfort Swivel hose allows 30°effortless range of motion without pulling or binding. (US Patent No. 7,188,869)

A BREATH OF FRESH AIR

Environmentally conscious topside natural breathing at depth

The ST1 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 we are doing our part for clean air when divers are out of the water. The legendary Atomic design means divers also breathe easy at depth.
