Apeks XTX40 DIN Dive Regulator with Nitrox DS4

Introducing the high-performance Apeks DS4 First Stage Regulator, perfect for high-percentage oxygen use. This compact regulator features four medium-pressure ports and one high-pressure port, providing convenient flexibility during your dives.One of the standout features of this regulator is the innovative Diver Changeable Exhaust system (DCE), allowing you to switch between a small exhaust tee and a large exhaust tee. This customization gives you the option of a wider exhaust tee for minimal bubble interference, ideal for underwater photography, or a smaller, compact tee for increased comfort.Moreover, the Apeks DS4 can easily be converted from a right-handed hose configuration to a left-handed one, offering versatile configuration options for your diving needs. Please note that this conversion should only be performed by an Apeks Authorised Service Technician to ensure proper functionality.Available in both yoke and DIN configurations, this regulator comes equipped with a braided flexi-hose, making it lighter, more flexible, and more durable. Whether you're exploring coldwater environments or using high levels of oxygen, the Apeks DS4 is designed to meet your needs.Don't miss out on the opportunity to enhance your diving experience with the Apeks DS4 First Stage Regulator. Upgrade to this reliable and versatile regulator today and elevate your underwater adventures to new heights.

• First Stage:
  • DS4 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, 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.
