Atomic Regulators Second Stage Design
The Most Personal Component
Your life depends on it with every “natural” breath
You need assurances about the part you put into your mouth – the single most important element of your diving system. Atomic second stages give you that assurance. The assurance of reliability with a low-maintenance design that is durable and does not require constant fine-tuning to perform perfectly. The assurance of easy and natural breathing at any depth. The assurance that corrosion of critical internal parts will not impair a single precious breath thanks to Titanium used in every Atomic second stage. Assurance is designed and built into each Atomic second stage you trustingly put into your mouth. So breathe easy...and have a great dive.
The Atomic Aquatics Second Stage Is Our Signature Design Statement
The foundation of any regulator second stage is the valve body, and nobody manufactures this crucial component to be as exacting and durable as Atomic. We machine our valve body from Ti-6 Al-4v solid Titanium on our very precise Swiss CNC machines. Because itís Titanium, itís very lightweight, and will last forever without showing a hint of corrosion (see the comparison photo on page 4). Performance of Titanium parts will never be altered by the effects of sea water.
Since the Atomic Titanium demand lever pivots off the valve body, a low-friction material with exceptional wear resistance is required to prevent metal-to-metal contact that leads to galling. Our Kevlar sleeve material endures millions of smooth cycles without wear.
The demand lever is the mechanical link to your breathing air supply. If it fails, air delivery stops. Because our demand lever is formed from a propriety Titanium alloy, our lever is immune from stress-induced fatigue or corrosion and breakage.
Breathe easier and deeper because of the pneumatically-balanced Poppet design. Having a balanced second stage means the diver will have the same low breathing effort regardless of how much air is remaining in the cylinder or any slight air pressure variation from the first stage.
Atomic redesigned this very basic second stage component into a large elliptical shape molded from a highly-resilient special grade silicone rubber. The valve attaches to a high-flow support grid, resulting in a dramatic reduction in your exhalation effort at depth.
Patented Atomic Automatic Flow Control (AFC)
The Atomic AFC is so advanced, we were granted a US patent for its design. The venturi effect inside a second stage makes it breathe easy, and the Atomic AFC eliminates the manual adjustment normally needed to regulate venturi effect as you dive deeper. No dials to turn or buttons to push ‚ but we include a rapid adjustment knob for rare special situations. A computer-designed airfoil inside the mouthpiece is connected to a pressure-sensing diaphragm, allowing the airfoil to change position with response to depth. The AFC is the reason Atomic regulators breathe with a comfortable natural feeling at any depth. (US Patent #5,678,541)
Atomic Patented Seat Saving Dynamic Orifice
Our Seat Saving Dynamic Orifice design prolongs the life of the low-pressure poppet seat to maintain the crisp "like new" factory tuning and prevent the second stage from leaking between servicing. This exclusive Atomic patented design allows the seat and orifice to make contact only when the regulator is pressurized. When not in use, the orifice automatically retracts away from the seat to prevent damage during storage. (US Patent #5,803,703)
Perhaps one of the most admired features of Atomic second stages is the patented comfort swivel which allows 30° rotational movement without binding or kinking. (US Patent #7,188,869)
