Atomic Aquatics ST1 Regulator
Why Stainless Steel & 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.

First Stage:

First stage machined from solid 316 Stainless Steel
Atomic Jet Seat high-flow piston first stage
Freeze protected factory-sealed first stage also prevents contamination such as silt and sand
Nitrox ready for mixtures up to 40%
First stage ports: 2 HP fixed / 5 LP on swivel cap

Here are some important answers to frequent questions regarding Atomic regulators...

What is Natural Breathing?

Atomic Aquatics has achieved what no other manufacturer has in a high-performance regulator – Natural Breathing. All Atomic regulators breathe with a natural and controlled air delivery sensation at any depth or breathing rate. Inhalation on the surface will feel the same as it does during your deepest dive. This is in part due to the AFC (Automatic Flow Control) employed in our second stages. This patented innovation is a simple device that adjusts the airflow automatically to compensate for the effects of depth. Atomic Aquatics regulators are the smoothest breathing regulators available...period.

What are the diving benefits of Titanium?

First, it is unbelievably lightweight which reduces stress during your dive and makes it a perfect travel regulator. Second, Titanium has no equal for corrosion resistance which means more safety, reliability and repeatable performance. And finally, its beautiful appearance stands apart from any other regulator.

Unparalleled light weight means less stress

In our mission to invigorate the diving experience, the first priority is on reducing stress – travel stress, gearing-up stress, jaw-clinch stress. The best way is to use the lightest material possible. But light weight must never compromise strength or durability. Titanium is the perfect solution. When you hold a Titanium Atomic regulator in your hand, you immediately realize the difference from other regulators. That means less stress for you from packing your gear bag, to donning, to even the final minutes of a long dive.
