Apeks XTX Tungsten Stage 4 Regulator Set


The Apeks XTX Tungsten Stage 4 Set is built on the XTX200 platform but with a truly unique, added feature: it is protected with a hard, durable Physical Vapor Deposition (PVD) finish, which is tougher than traditional chrome plating. The coating is made of high quality grades of Titanium, Zirconium and Chromium. The result not only looks extremely attractive, but protects your investment from normal diving abuse.

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 for additional hose routing. The 5th port also has with the additional bonus of an integrated heat exchanger (Tungsten, XTX200 and XTX100 first stages only).

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 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).

The stage 4 set is completed with Apeks XTX50 octopus and double gauge.

First Stage:

  • FSR 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, mold, 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.

Octopus:

  • The XTX50 Octopus has a breathing effort control knob.
  • Large purge button
  • Can be converted from a right-handed hose configuration to a left handed one.
  • Braided flexi-hose
  • Suitable for coldwater use.
  • Compatible with EAN40 out of the box.
  • Pneumatically-balanced second stage results in smooth, easy breathing.
  • The large venturi lever
  • A silicone exhaust valve improves the breathing performance of the regulator.
  • The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue.

Console:

  • The gauge case is made from nickel plated brass
  • The dial window is made of highly shock resistant material (anti-splinter polycarbonate)
  • A specially designed housing protects the gauge and HP hose fitting from accidental damage
  • A large loop area designed into the housing allows for easy attachment.
  • There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing.
  • Dials have a long phosphorescent effect for better reading in poor visibility conditions
  • There are 2 attachment areas integrated into the design for position flexibility
  • This may be a compact design but the displays are vivid and clear - perfect for diving. For example, the depth gauge spreads the first half of the scale and in total shows a range down to 230 feet
  • Depth gauge has resettable max depth indicator
