About Apeks XTX40/DS4 DIN Oxygen Regulator
The XTX technology is available in an oxygen model, designed for oxygen percentages between 0-100%. This compatibility and reliability make it an ideal choice for technical divers performing high O2 percentage deco stops. With green and yellow cosmetic pieces, the regulator is easily identifiable as dedicated to high-percentage oxygen use. It features a unique over-balanced diaphragm design, providing superior performance at depth. The compact DS4 first stage has four medium-pressure and one high-pressure port, and an environmental dry system to prevent ice build-up and contamination.
The pneumatically balanced second stage ensures smooth and easy breathing. XTX purge buttons offer a 2-stage progressive purge for controlled flow rate or full effect. A large venturi lever with a soft touch rubber grip makes it easy to locate and use. The opening effort control knob ensures divers remain in control, while active protection against infection is provided through an additive in all molded parts.
A silicone exhaust valve enhances the regulator's breathing performance, and the Comfo-Bite mouthpiece virtually eliminates jaw fatigue. The patented heat exchanger dissipates cold caused by gas expansion and draws in ambient water warmth. The optional Diver Changeable Exhaust (DCE) system allows switching between small and large exhaust tees, catering to underwater photographers or those seeking a compact regulator.
The regulator can be converted from a right-handed to a left-handed hose configuration, but this must be done by an Apeks Authorized Service Technician. A braided flexi-hose is included, offering lighter weight, more flexibility, and durability. The regulator weighs 38.8 oz (1100g) and comes with an owner's manual.
