Apeks - XTX40 NITROX + DS4 DIN O2
Please be aware that due to a facility move, some products from Apeks and Aqualung are taking a month or more to ship.
Now you can get XTX technology in an oxygen model. This regulator is built for oxygen percentages between 40 - 100%. This compatibility coupled with its excellent reliability make it the choice for technical divers doing high 02 percentage deco stops.
FEATURES:
â– This compact first stage has one high-pressure port and four medium pressure ports
â– Green and yellow cosmetic pieces clearly identify that this regulator is dedicated to
high-percentage oxygen use
â– The first stage is dry-sealed preventing the entry of contaminants as well as ice formation on
the main spring
â– The XTX40 second stage is pneumatically balanced for very easy breathing.
â– Due to its innovative Reversible Venturui System (RVS) the second stage can be configured
into a right hand or left hand orientation
â– The venturi lever is easy to use even with the thickest of gloves
â– Suitable for coldwater use PN
DETAILS:
DS4 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 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.
- 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-biteâ„¢ 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.
