This set contains both the ATX40 First and Second Stage as well as the ATX40 Octopus, making a huge saving on this high performance regulator set.
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 10 C / 50 F).
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.
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.
This octopus is based upon the XTX40 second stage and includes left / right hand reversibility, 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.
