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, 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. An easy-to-grip opening effort control knob keeps the diver in control. The second stage is manufactured with active protection against infection as all moulded 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. Apeks XTX 40 Occy The XTX40 Octopus provides the same features and performance as the XTX40 second stage and includes left /right-hand reversibility. It comes with a high visibility yellow front cover and a 36” yellow hose. Suitable for cold water use (below 10 C / 50 F). Features 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. Can be converted from a right handed hose configuration to a left-handed one. 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 Authorised Service Technician. 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. Pneumatically-balanced second stage results in smooth, easy breathing.
