Apeks ATX40 Regulator

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).

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.
