Description
- This high-performance regulator boasts an over-balanced first stage coupled with a pneumatically balanced second stage.
- The smooth, quiet breath is sure to enhance your diving enjoyment.
- Suitable for cold water use thanks to its first stage environmental dry seal and second stage heat exchanger.
- Compatible with EAN40 out of the box.
First Stage
- Uses the DS4 first stage
- Unique over-balanced, diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
- 1 HP port and 4 MP ports are available.
- An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
- Available in DIN and yoke.
Second Stage
- Pneumatically-balanced second stage results in smooth, easy breathing.
- The large purge button on the ATX is easy to operate even with thick gloves.
- The integrated venturi control provides a performance boost at depth while preventing unwanted freeflow at the surface.
- An extremely efficient exhaust valve improves the breathing performance of the regulator.
- The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue.
- A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
- Offers a compact, integrated exhaust tee.

ATX Octopus
- Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.
- Pneumatically-balanced second stage results in smooth, easy breathing.
- A silicone exhaust valve improves the breathing performance of the regulator.
- The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue
- Suitable for cold water use (below 10 C / 50 F).

Pressure Gauge
- The gauge case is made from nickel plated brass
- The dial window is made of highly shock resistant material (anti-splinter polycarbonate)
- A specially designed housing protects the gauge and HP hose fitting from accidental damage
- A large loop area designed into the housing allows for easy attachment.
- There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing.
