Apeks XTX 50 Oxygen Regulator Din – Nitrox

Apeks XTX 50 Oxygen Regulator Din – Nitrox

Choose the dedicated oxygen-clean XTX50 for an appropriately maintained oxygen-service configuration. Its DST first stage provides a rotating turret, while the XTX50 second stage gives you separate Venturi and inhalation-effort adjustment. This listing is for the oxygen-cleaned model, not the standard air regulator.

Features and benefits

• Over-balanced first stage. The diaphragm mechanism increases intermediate pressure slightly faster than surrounding pressure as you descend, helping compensate for denser breathing gas at depth.
• Dry environmental chamber. The sealed chamber keeps water and sediment away from the first-stage spring mechanism and supports resistance to freezing in cold water.
• Rotating hose turret. The low-pressure turret turns to follow hose direction, making it easier to arrange hoses without tight bends around the first stage.
• Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
• Inhalation-effort adjustment. The adjustment knob lets you change the effort needed to start a breath, so you can tune the response within the regulator’s operating range.
• Venturi control. The lever changes airflow assistance inside the second stage. Use the pre-dive setting for surface handling and the dive setting as directed in the manual.
• Progressive purge. The purge responds to how firmly you press it, giving you control over the flow used to clear the second stage.
• Reversible hose routing. An authorised technician can configure the second stage for left- or right-hand hose entry to suit your equipment layout.
• Interchangeable exhaust. The exhaust options let you choose a compact layout or wider bubble diversion to suit your diving and field of view.
• Comfo-Bite mouthpiece. The silicone palate bridge supports the second stage with less need to clench your jaw, which can make longer dives more comfortable.
• Heat exchange. The heat exchanger transfers warmth from the surrounding water to the valve area, helping counter the cooling that occurs as gas expands.
• Dedicated oxygen-service configuration. This oxygen-clean version is intended for appropriately specified enriched-air and oxygen systems. Its components, gas supply and handling must preserve oxygen cleanliness.
• Colour identification. The oxygen-service colour scheme helps distinguish this regulator within a multi-cylinder configuration; always analyse and label the cylinder gas separately.

Setup and compatibility

Connection: DIN. Choose the fitting that matches your cylinder valve and its pressure rating. Dedicated oxygen-service model. Maintain oxygen-clean condition throughout filling, handling and servicing, and confirm the complete system is suitable for the intended mixture. Follow Apeks oxygen-service requirements. A fifth-port upgrade is optional and sold separately unless expressly included in your selected configuration.

Care, rinsing and storage

Maintain this regulator’s oxygen-clean condition throughout handling, use and storage. After a dive, follow the Apeks oxygen-regulator manual’s rinsing procedure, using a compatible cylinder and gas supply that preserve oxygen cleanliness. Keep the complete system pressurised while submerging the stages and connected hoses in clean fresh water, with the cylinder secured.

Keep the system pressurised throughout rinsing. Lift it out and dry the first stage and cylinder connection before closing the valve, releasing pressure and disconnecting. Fit a clean, dry dust cap. Avoid oils, grease and cleaners that are not approved for this oxygen-clean equipment; ordinary wetsuit shampoo is not a substitute for an oxygen-cleaning procedure.

Dry in the shade and store protected from contamination with the hoses loosely curved. Inspect the mouthpiece, hoses and connections before use. Follow the manual’s service schedule and use an authorised Apeks technician trained in oxygen service for repairs, internal adjustments or restoring oxygen cleanliness.
