  • 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.
  • 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.

Description

Apeks’ mid-range XTX40 regulator system offers superb performance in any environment, at an ideal price.

Designed with technical divers in mind, the DST 1st stage is dry-sealed. This prevents ice build-up in the 1st stage for superior cold water performance and eliminates silt ingress, preventing contamination. When you’re diving to extreme depths, the surrounding water pressure can constrict your regulator hoses, making breathing more difficult. The DST’s over-balanced diaphragm counteracts this effect by increasing the air pressure in your hoses the deeper you go for effortless breathing performance throughout.

The DST 1st stage offers 4 low-pressure ports and 2 high-pressure, with an optional 5th port which allows you configure technical regulator setups or optimally route your hoses. The swivel head further increases the flexibility of the 1st stage ensuring you can route your hoses in a variety of ways, kink free.

The XTX40 second stage provides clear, effortless breathing thanks to it high-quality internal design. Pneumatically balanced it’s able to deliver consistent clear airflow even when your tank is nearing empty. Like all Apeks regulators the XTX40 comes with a Comfo-Bite mouthpiece which eliminates jaw fatigue and helps to reduce dry mouth for more comfortable breathing.

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 MP 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 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-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.
