Apeks XTX200 & XTX40 Regulator Set Din
The XTX 200 is second only to the Black Sapphire and quite rightly enjoys its position towards the top of the Apeks regulator range. The definitive blend of style and high performance, every detail on this product has been carefully designed to offer a regulator of the highest quality.
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. It is suitable for cold water use (below 10 C / 50 F).
Apeks XTX200 Regulator Features
First Stage:
- FSR style first stage.
- Highly polished bright chrome plating.
- Compact one-piece body.
- 4 angled medium pressure ports, 4 x 3/8” UNF.
- 2 angled high-pressure ports, 2 x 7/16” UNF.
- Optional 5th port.
- Removable ARCAP valve seat.
- Unique over-balanced diaphragm design—as the diver descends, the over-balancing feature allows the medium-pressure gas in the hose to increase faster than ambient. This results in superior performance at depth.
- An environmental dry system keeps water out of the main spring chamber, thus preventing ice buildup and keeping silt and contamination out.
Second Stage
- The 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.
- 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, mould, yeast and algae.
- A silicone exhaust valve improves the regulator’s breathing performance.
- 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 XTX40 Occy 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, an APEKS Authorised Service Technician must ONLY perform this procedure.
- Braided flexi-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.
