XTX40 DS4 RegulatorPerformance, Control and Safety Underwater

The XTX40 DS4 regulator set impresses with its reliable operation, high-quality construction and classic Apeks design. The combination of an over-balanced diaphragm design and a pneumatically balanced second stage ensures stable breathing performance at any depth. With features such as the Comfo-bite mouthpiece, active hygiene protection mechanisms and optimised hose routing, this set is suitable for advanced divers as well as beginners who value quality.

DS4 First StageOver-balanced Diaphragm Design for the Highest Demands

• Over-balanced diaphragm design for a rapid increase in intermediate pressure during descent
• Externally sealed system protects against dirt and ice formation
• Angled high-pressure and intermediate-pressure ports for optimum hose routing
• Suitable for cold water thanks to the dry main spring chamber
• Robust construction and durable materials

The DS4 first stage offers above-average performance at depth thanks to its innovative diaphragm design and ensures a constant gas flow even as ambient pressure increases. The fully sealed system minimises the risk of icing and provides reliable protection against external influences. The carefully considered arrangement of the ports enables flexible and secure hose routingideal for technical and recreational dives.

XTX40 Second StageRobust Second Stage with Good Breathing Performance and Infection Protection

• Pneumatically balanced construction for consistent breathing comfort
• Large, two-stage purge button for precise operation
• Easy-grip Venturi lever with rubber coating
• Active protection against bacteria, viruses and fungi
• Comfo-bite mouthpiece to help prevent jaw fatigue

The XTX40 second stage stands out with very low breathing resistance and precise adjustment options. The large Venturi lever and innovative purge button enable easy handlingeven when wearing gloves. The Comfo-bite mouthpiece ensures relaxed diving, even during longer dives. The silicone exhaust valve improves the regulators breathing performance.

A particular feature of this second stage is its active protection against infections. All plastic components contain an additive that provides effective protection against viruses, mould, algae and yeast, as well as protection against E. coli, other bacteria and fungi, and even kills MRSA.

AT OctopusReliable Emergency Companion

• Pneumatically balanced construction for smooth breathing
• Full Venturi control to prevent free flows
• Comfo-bite mouthpiece for maximum comfort
• Designed for water temperatures above 10 °C
• Directly compatible with EAN40 after purchase

The AT Octopus complements the set with a reliable secondary air supply featuring the same comfort and safety characteristics as the primary second stage. Full Venturi control prevents unwanted air flow when the octopus is not in use. Thanks to the comfortable mouthpiece, breathing effort remains low even in stressful situations. Its design for temperatures above 10 °C makes it a solid choice for dives in temperate waters.

Frequently Asked Questions About the XTX40 DS4 Regulator Set with AT Octopus

Is the XTX40 DS4 regulator set with AT Octopus suitable for cold-water diving?

Yes, the first stage is suitable for cold water because it features an externally sealed system that prevents ice formation and keeps the spring chamber dry. The second stage is designed for water temperatures above 10 °C.

What are the advantages of the first stages over-balanced diaphragm design?

The over-balanced diaphragm design ensures that the intermediate pressure increases more rapidly than the ambient pressure during descent. This results in consistently high breathing performance, even at greater depths.

Who is the regulator set suitable for?

The set is aimed at divers of all experience levels who value reliability, ease of use and high breathing performancefrom beginners to advanced recreational or technical divers.

How often should the regulator be serviced?

The regulator should be serviced annually or after 100 dives, in accordance with the manufacturers specifications. Servicing must be carried out by a qualified technician. In addition, carry out a brief visual inspection of your regulator before every use and a thorough check before every trip or after a longer break. This should include the mouthpieces, hoses, visible O-rings, signs of corrosion, the inflator hose connection, air tightness and the purge button. Proper regulator care is also important.

Is the set directly compatible with Nitrox (EAN40)?

This regulator is factory-approved for use with Nitrox mixtures containing up to 40% oxygen. Please always observe local regulations and legal requirements. In Germany, for example, a separate regulator with a special connection is required for diving with Enriched Air Nitrox.

What hygiene benefits does the regulator set offer?

All moulded components of the second stage contain an additive that kills MRSA and provides protection against E. coli and other bacteria, as well as viruses, fungi, mould, yeast and algae, thereby improving hygiene while diving.
