Pneumatically-Balanced Poppet Second Stage
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.
Competitors: Balanced Poppets are the norm these days. If the second stage you are
researching isn’t a balanced design, the design is too outdated to consider buying.
Elliptical Exhaust Valve
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.
Competitors: Other regulators are fitted with very outdated flat and round valve
designs that date back to the sixties.
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)
Competitors: Others use a diver-controlled switch or dial to manually adjust the
venturi effect inside the second stage as dive depth changes. This requires distracting
thought and aggravation if you turn the dial the wrong way. The Atomic AFC lets you enjoy
your dive...automatically.
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)
Competitors: Our competitors would like to have this patented Atomic feature. One
of the biggest problems with all standard second stages is the contact area between the
sharp metal orifice and the soft rubber low-pressure seat. In these fixed orifice designs,
the seat and orifice are pressed together by the demand lever spring during storage,
resulting in a deep groove or cut in the seat. Over time, this can cause a second stage to
develop a leak even if it hasn't been used. Others also use plastic or brass for their orifice
– Atomic uses Titanium for longevity.
Comfort Swivel
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. See page 37 for full
features and details of the comfort swivel. (US Patent #7,188,869)
