The world’s first “Green” regulator! Compared to other metals that require surface plating and processing, our stainless steel is more earth friendly, and our type 316 stainless steel has twice the strength and corrosion resistance of brass. The fully stainless first stage body has a swivelling 5 port low pressure cap, 2 high pressure ports and comes environmentally sealed. 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. 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.
