  • Description

    The Apeks XTX40 Stage 3 Regulator Set is perfect for any diver that wants outstanding cold water reliability and high performance at a very affordable price. The set includes the DST first stage, an XTX40 second stage and a matching XTX40 octopus.

    The Apeks DST is a high performing balanced diaphragm first stage that is fitted with an environmental seal to improve cold water reliability by preventing water from coming into contact with the internal components. The DST features two high pressure ports on the main body and four low pressure ports mounted in a swivelling turret. An additional fifth port can be added using an upgrade kit that can be installed by an authorised technician.

    The XTX40 delivers excellent performance thanks to a pneumatically balanced full metal barrel valve that uses an inline heat sink to help prevent excessively low temperatures that could lead to a freeflow. The XTX40 housing is designed to be switched from right to left handing by a technician, making it ideal for divers that want to move on to twinset or sidemount configurations at a later date. The XTX40 is also fitted with a diver adjustable venturi lever to control the flow of air within the housing, providing pre-dive and dive settings.

    The XTX40 Octopus provides the same high performance and features but is finished with a high visibility yellow front cover, lever and hose.

  • Features

    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.
