Description The APEKS XTX50/40 regulator set caters to divers seeking a feature-rich regulator. It has four low-pressure ports arranged on a rotating turret, ensuring optimal hose routing while minimizing sharp bends, and two high pressure ports. An innovative Diver Changeable Exhaust system (DCE) allows users to switch between small and large exhaust tees, offering flexibility for different diving scenarios. This includes a wider tee for reduced bubble interference, crucial for underwater photography, and a narrower tee for a more compact, comfortable setup. The regulator comes with both sets of exhaust tees. Additionally, an optional 5th port is available for sidemount or twin cylinder configurations. The regulator can also be converted from a right-handed hose setup to a left-handed one, a process that must be performed by an APEKS Authorized Service Technician. Available in both yoke and DIN configurations, the XTX50 features braided flexi-hoses as standard, enhancing durability and flexibility. First Stage Features: Uses the DST 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. 2 HP ports and 4 LP ports on a rotating turret are angled for optimum hose routing. An environmental dry system keeps water out of the main spring chamber thus preventing ice build-up and keeping silt and contamination out. Second Stage Features: Pneumatically-balanced second stage results in smooth, easy breathing. The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used – press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc. The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation. Easy-to-grip opening effort control knob keeps the diver in control. The second stage is manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mould, yeast and algae. A silicone exhaust valve improves the breathing performance of the regulator. The Comfo-bite mouthpiece virtually eliminates jaw-fatigue. A heat exchanger which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
