Apeks ATX Regulator Set

Despatch in 6-10 Days
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).

Apeks ATX Stage 4 Regulator Set

Set includes:
  • First stage DS4
  • APEKS ATX 40 second stage with whip
  • Octopus Apeks ATX 40 with 100cm yellow whip
  • Apeks pressure gauge with metal case
  • Nauticamare Tribute dispenser bag.
  • The Apeks regulator kit is perfect for the diver who intends to dive at any time of the year, in fact, thanks to the DS4 first stage with dry chamber membrane, this sub regulator is also suitable for cold waters.
  • The Apeks regulators are characterized by excellent performance, even in deep dives, with the use of nitrox or trimix mixtures.
  • Both second stages are equipped with venturi effect regulation. 
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.
