Demo-Apeks Xtx20 Regulator Yoke

This regulator has the performance of the XTX40 but without the cold water features. It is well suited for warm water conditions (above above 10º C / 50º F) and is exceptional value for money.

Features an innovative Diver Changeable Exhaust system (DCE). This system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. Only the narrow exhaust tee is supplied with the regulator.

The second stage can be converted from a right-handed hose configuration to a left-handed configuration. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician.

Available in yoke or DIN configuration.

Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.

Compatible with EAN40 out of the box.

First Stage:

• Use the UST first stage.


• A balanced, diaphragm design – provides consistent easy breathing from start of dive until end.


• 1 HP port and 4 MP ports are angled for optimum hose routing

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 center 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.


• The 2nd 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.
