Atomic Aquatics ST1 DIN Regulator

A Breath of Fresh Air.

The Atomic Aquatics ST1 Swivel Sealed Regulator has a Stainless Steel First-Stage. 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 First-Stage is Machined from Solid 316-Grade Stainless Steel.

The ST1 Second-Stage is a Balanced Linear Flow Design for Extremely Easy Breathing at all Depths and Dive Conditions. Like the First-Stage the ST1 Second-Stage is Built-to-Last with a Titanium Demand Valve Body, Lever and Sealing Orifice. The Diaphragm is made from High Quality Silicone Rubber. This Pneumatically-Balanced Poppet Second-Stage has Atomics Patented Seat Saving Dynamic Orifice which unlike most Second-Stage Orifices is a Floating Valve Design which Reduces Wear on the Second-Stage Poppet Seat when the Regulator is not pressurized adding Life to this Important Seal.
