XTX 50 Oxygen Regulator Features:

Four medium-pressure ports are all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose.

Features an innovative Diver Changeable Exhaust system (DCE). This system allows the diver to change from a small exhaust tee to a large exhaust tee. This gives the user a choice of, a wider exhaust tee for minimal bubble interference (essential for underwater photography) and a narrow exhaust tee for a smaller, compact, comfortable regulator. The regulator is supplied with both sets of exhaust tees.

Optional 5th port is available for sidemount or twin cylinder setups.

It can be converted from a right-handed hose configuration to a left-handed one. Changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician.

Available in yoke or DIN configuration.

Braided flexible hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.

Suitable for coldwater use (below 10 C / 50 F).

Compatible with EAN40 out of the box.

First Stage:

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.

Second Stage

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, making it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.

An easy-to-grip opening effort control knob keeps the diver in control.

The second stage is manufactured with active protection against infection. All moulded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is 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.
