Apeks XTX40 DS4 RegulatorPrecision and Safety Underwater

The Apeks XTX40 DS4 regulator impresses with its robust construction and excellent breathing performance at all depths. The over-balanced diaphragm design ensures consistent breathing comfort, even during demanding dives. This regulator is especially suitable for divers who value reliability and ease of use. The combination of high-quality materials and practical features makes the XTX40 DS4 a dependable choice for both sport and ambitious recreational divers.

First StageOver-balanced Diaphragm Design and Dry Seal

• Over-balanced diaphragm design for optimised performance at depth
• Environmentally sealed system (Dry Seal)
• Chrome-plated, saltwater-resistant brass
• 1 high-pressure port (7/16″ UNF), 4 medium-pressure ports (3/8″ UNF), angled for optimal hose routing
• Cold water rated and easy to service

The first stage of the XTX40 DS4 is based on an over-balanced diaphragm design, which increases the intermediate pressure as you descend, ensuring stable breathing performance at any depth. The environmentally sealed system reliably keeps out moisture and dirt, which is particularly advantageous for dives in cold or challenging waters. The high-quality construction and thoughtful arrangement of the ports guarantee safe and comfortable use.

Second StagePneumatically Balanced and Hygienically Protected

• Pneumatically balanced design for consistent breathing comfort
• Large, two-phase XTX purge button for controlled clearing
• Ergonomic Venturi lever with rubber cover
• Active protection against bacteria and viruses through special additives
• Comfo-bite mouthpiece, replaceable exhaust tee
• Patented heat exchanger for increased freeze resistance

The second stage of the Apeks XTX40 DS4 is pneumatically balanced, providing exceptionally light and consistent inhalation and exhalation. The large XTX purge button allows precise control when clearing, while the Venturi lever and Comfo-bite mouthpiece significantly enhance operation and comfort. Integrated protection against germs and a patented heat exchanger make this regulator particularly suitable for cold and hygiene-sensitive environments.

Frequently Asked Questions about Apeks XTX40 DS4 Regulator

Is the Apeks XTX40 DS4 regulator suitable for cold water diving?

Yes, the XTX40 DS4 is cold water rated. The environmentally sealed first stage and patented heat exchanger in the second stage provide reliable protection against freezing and ensure safe operation even at low water temperatures.

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

The over-balanced diaphragm design ensures that the intermediate pressure increases faster than the ambient pressure when descending. This keeps breathing effort consistently low even at great depths, and the regulator reliably delivers air.

Maintenance must be performed by a qualified technician, for example in our Scubaonline specialist workshop for regulator servicing. Additionally, carry out a quick visual inspection before each use and a thorough check before every trip or after long breaks (including mouthpieces, hoses, visible O-rings, signs of corrosion, inflator hose connection, tightness, purge button). Proper care of the regulator is also importantmore information can be found in our guide Cleaning, maintaining and storing diving equipment.

What makes the second stage of the XTX40 DS4 special?

The second stage features a pneumatically balanced construction, a large Venturi lever for easy operation, and effective protection against bacteria and viruses thanks to an additive in the plastic components. The Comfo-bite mouthpiece and heat exchanger increase comfort and safety while diving.
