- Apeks XTX50 Regulator (Yoke) -
Introducing the Apeks XTX50 regulator, perfect for discerning divers seeking top-notch features at an affordable price. This popular regulator boasts a rotating turret with four medium-pressure ports, ensuring ideal hose routing without sharp bends. An optional 5th port is available for side mount or twin cylinder configurations.
Experience superior performance with the unique over-balanced diaphragm design, which enhances medium pressure gas delivery as you descend. The regulator's optimally angled high-pressure and medium-pressure ports further improve hose routing. An environmental dry system safeguards the main spring chamber from water, ice, and contaminants.
Enjoy smooth, effortless breathing with the pneumatically-balanced second stage. The XTX50 features large, user-friendly purge buttons with two-stage progressive action for precise control. The venturi lever, coated in soft-touch rubber, is easy to locate and use while resisting grit ingress for smooth operation. An easy-to-grip control knob keeps you in command, while the innovative antimicrobial additive in molded parts provides active infection protection.
The silicone exhaust valve enhances breathing performance, and the Comfo-Bite mouthpiece minimizes jaw fatigue. The patented heat exchanger ensures warmth and prevents gas expansion-induced cold.
The XTX50 also includes a Diver Changeable Exhaust (DCE) system, allowing you to switch between small and large exhaust tees for optimal bubble management or a compact, comfortable fit for scuba diving. Both exhaust tees are included with the yoke regulator. Easily convertible from right- to left-handed hose configurations, the XTX50 is equipped with lightweight, flexible, and durable braided flexi-hoses.
This cold-water-ready regulator is compatible with EAN40 straight out of the box and includes an owner's manual. Please note that only APEKS Authorized Service Technicians should perform left-handed configuration adjustments.
- Apeks XTX40 Octopus -
The Apeks XTX40 Octopus provides the same features and performance as the XTX40 second stage and includes left / right hand reversibility. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must only be performed by an Apeks Authorized Service Technician. Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable. Suitable for cold-water use 50 Degree F (10 Degree C) and is compatible with EAN40 out of the box.
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 center 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, mold, 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. Regulator comes with a high visibility yellow front cover and a 36" (91.5cm) yellow hose.
