Apeks XTX200/XTX40 Regulator and Octopus

The XTX200 is for the discerning diver who wants the benefits of a feature-rich regulator at a moderate price. This popular regulator has four medium-pressure ports all mounted on a rotating turret, for optimal hose routing while eliminating sharp bends in the hose.

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.

Optional 5th port is available for sidemount or twin cylinder set ups.

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.

First Stage:

The Apeks FSR flagship first stage is a unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the intermediate pressure gas in the hose to increase at a rate faster than ambient resulting in superb performance at extreme depths. The forged and polished chrome plated body has two standard high pressure 7/16-inch fixed angle ports plus four standard high-flow low pressure 3/8-inch fixed angle ports in an orientation that Apeks describes as being optimum for hose routing. An optional upgrade adds a 5th port to the end. The beefy body functions as a heat sink together with an environmental seal keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out. The FSR comes standard with a DIN connector and is Nitrox Ready.

Unique among the Apeks XTX series first stages, only the FSR has a removable ARCAP high-pressure seat crown. ARCAP is a high-tech metal alloy with very high tensile strength and is resistant to the effects of low temperatures and temperature change. The insulation from the surrounding environment provided by the beefy forged body, together with the replaceable HP seat made of the ARCAP alloy, makes the FSR even more adapted to diving in cold water.

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-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.
