Apeks XTX40 DST Regulator

The Apeks XTX40 DST may be a mid level regulator in the Apeks range but itis always classed as a high performance regulator in independent reviews. It comes with all the features of the highly successful XTX50 except for the diver adjustable breathing resistance control.

The DST first stage has four low pressure ports all mounted on a rotating turret for optimal hose routing and two high pressure ports to accommodate an analogue gauge or console as well as a wireless transmitter for a dive computer. The DST can also be fitted with an optional fifth low pressure port upgrade that adds an extra port on the of the rotating turret.

The XTX 40 second stage features an innovative Diver Changeable Exhaust system (DCE). The 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. Only the narrow exhaust tee is supplied with the regulator.

This can be converted from a right-handed hose configuration to a left-handed one by our authorised service technicians before shipping, find out more here.

Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.

Suitable for cold water use (below 10 C / 50 F).

Compatible with EAN40 out of the box.

Features

First Stage:

• Use the DST 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 LP ports on a rotating turret are angled for optimum hose routing.
• An environmental dry system keeps water out of the main spring chamber thus preventing ice build-up 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 moulded 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.
