Apeks XTX50 Dive Regulator

Introducing the Apeks XTX50 Regulator, designed for optimal performance and comfort underwater. With four medium-pressure ports mounted on a rotating turret, hose routing is made easy while sharp bends are eliminated. The innovative Diver Changeable Exhaust system allows users to switch between a small exhaust tee for minimal bubble interference, ideal for underwater photography, and a large exhaust tee for a compact and comfortable regulator.

This regulator comes equipped with both sets of exhaust tees, and an optional 5th port is available for side mount or twin cylinder setups. The XTX50 can also be converted from a right-handed hose configuration to a left-handed one, a process that is quick and simple when performed by an Apeks Authorized Service Technician.

Available in both yoke and DIN configurations, the XTX50 features braided flexi-hoses that are lighter weight, more flexible, and more durable. Suitable for cold water use below 10°C/50°F, this regulator is also compatible with EAN40 straight out of the box.For top-notch performance and versatility underwater, choose the Apeks XTX50 Regulator.

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 MP 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 buildup and keeping silt and contamination out.
• 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 (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
