ATX First & Second Stage + ATX Octopus + Pressure Gauge 

Before the XTX range of regulators came along, the ATX models ruled the seas. The ATX is still available today and offers a fully balanced first and second stage with cold water capability (can be used in all temperatures including those below 10º C / 50º F). The ATX Octopus is based upon the ATX second stage with proven cold water capability and the performance you would expect from an Apeks pneumatically balanced valve. It features a diver-adjustable venturi control, a high visibility yellow front cover, yellow accent pieces and a 36” yellow hose.

The Apeks Submersible Pressure (contents) Gauge, with an internal Bourdon pressure measuring mechanism, gives you clear information on the gas contents of your cylinder. The gauge indicates the cylinder bottle pressure and the dial range is from zero to 5000psi (a metric version is also available with a range up to 360 bar). The dial face is designed with clarity in mind by being uncluttered, with large black figures on a luminous background giving a long phosphorescent effect. This makes viewing as easy as possible, even in poor visibility conditions.

 

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.

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.
