Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.
The regulators have been specially cleaned and assembled in our purpose built class 'J' (10,000) Clean Room using oxygen safe components and lubricants and are available in yoke ('A') clamp or DIN fitting.
Features & Benefits
Nitrox equipment will be supplied in Europe in accordance with the EN 144-3 and the EN13949 which states that equipment sold in CEE (European Community) countries over 21% and up to 100% will be manufactured with the special M26 fitting.
Features an innovative Diver Changeable Exhaust system (DCE). This system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. The regulator is supplied with both sets of exhaust tees.
An optional 5th port is available which features the additional bonus of an integrated heat exchanger (available on the Tungsten, XTX200 and XTX100 first stages).
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.
Available in yoke or DIN configuration.
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.
- 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 at a rate 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
- 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 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.
