Auxiliary Emergency Breathing Systems and the new European Standard Our new XTX regulators are the first in the world to meet this major Safety Standard.

The Apeks XTX200 topped independent regulator reviews and was respected as one of the best regulators in the world. To improve on this was not an easy task. Our new XTX200 takes all that is good from its predecessor and offers even more. Not only has the regulator been brought right up to date with stunning looks but we have also made functional improvements. The 1st stage has been redesigned to offer improved gas flow which now enables this to accept a 5th port (pictured right, not included as standard). The 2nd stage is now manufactured with active protection against infection as all moulded 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. One of the new features is a purge button that is larger for easier diver use and also now offers a dual flow rate purge for different operations. We have also redesigned the diver adjustable controls with improved ergonomics on the Venturi lever and the Cracking Resistance Control. Every aspect of the new XTX200 has been thought about to bring the whole unit together so that it not only performs exceptionally well but also looks the part.


The XTX200 can be converted from a right handed hose configuration (as supplied from the APEKS factory) to a left handed one. This regulator also features a Reversible Venturi System (RVS). Changing the regulator to a left handed configuration is both quick and simple and can be performed by any APEKS Authorised Service Technician.

The 2nd stage of the XTX200 features the Diver Changeable Exhaust System (DCE) giving divers the ability to change from a small to a large exhaust. It offers the user a choice of the wider exhaust tee for minimal bubble interference (great for underwater photography) and the narrow exhaust tee for a smaller compact comfortable regulator (ideal for travel). The exhausts are made from strong, yet light-weight material, essential for the diving environment. We supply different coloured mouthpieces and exhausts for regulator individualisation, useful when using multiple regulators with different mixes.

This new XTX200 incorporates a new design of front cover manufactured using high strength materials which protect the most vulnerable part of the demand valve. Quality chrome plated metallic features immediately identify this regulator as a top of the range model.

The design of the purge button has improved even further than its predecessor. The original XTX200 improved on the purge itself. Due to the open design the purge was self clearing and prevented debris build-up. All this is still evident in the new model but with added benefits. The purge button is now larger for easier operation and also offers a dual flow rate purge.

The new Venturi lever still reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation. The new version has been re-designed with improved ergonomics.

A swivel hose connection is available at an extra cost. This allows the demand valve end of the hose connection to rotate and pivot, providing a more comfortable fit.

The silicone exhaust valve of the XTX200 improves breathing performance.

Weight: Yoke 1272g ... DIN 1142g



The graph below shows the breathing cycle of the Apeks XTX200 regulator at 0.56 J/L. Performance is calculated by plotting and recording this cycle. The inhalation line begins on the right hand side and runs along the bottom to the left. The first oscillation (termed the cracking spike) represents the effort required to initially open the valve and begin air delivery. Even at the testing depth of 50 metres the graph shows the low Work Of Breathing (WOB), indicating the diver is expending almost no energy in maintaining air flow. The cycle continues and the upper line (left to right) represents the WOB whilst exhaling (greater due to increased gas density at depth). The total WOB is calculated by measuring the total area within the loop.
