The Tek 3 combines all the advanced technology of the Apeks first stage range.
The outlets are designed to allow perfect symmetry of hose routing and are oriented downwards for the requirements of technical diving.
It allows optimal accessibility to the valves when using two-bottle blocks.
The innovative DCE system allows the diver to modulate the size of the whiskers, short or long, the latter allowing the bubbles to be drawn backwards to improve the field of vision. Both versions are included with the regulator.
Compensated second stage for easy, smooth breathing
The XTX purge button is large and easy to operate. It is progressive and offers two flow rates. Press on the sides for low flow, convenient for controlling the inflation of a parachute. Press on the center for maximum flow, ideal for purging a regulator.
Reversible second stage and interchangeable right/left hose configuration can be mounted on either side of the first stage. Operation is quick and easy but must be performed by an Apeks authorized technician.
Available in DIN
Braided hoses are standard on all regulators. They are lighter, more flexible and more resistant.
EAN40 compatible ex-factory (non-CE only).

The first stage has 4 MP outlets which are mounted on a swivel turret. The hose routing is optimal and eliminates sharp bends in the hoses.

The innovative DCE system allows the diver to modulate the size of the whiskers, short or long, the latter allowing the bubbles to be drawn backwards to improve the field of vision. Both versions are included with the regulator.

A 5th MP outlet is available for sidemount or twin-bottle block installations.

Reversible second stage and interchangeable right-left flexible configuration, which can be mounted on either side of the first stage. Operation is quick and easy but must be performed by an Apeks authorized technician.

Available in DIN

Braided hoses are standard on all regulators. They are lighter, more flexible and more durable.

Can be used for cold water diving.

The first stage
First stage DST
Overcompensated diaphragm regulator - as the diver descends, overcompensation allows the medium pressure to increase faster than the hydrostatic pressure. Performance at depth is increased.
2 HP and 4 MP outlets are angled for optimum hose routing.
The dry chamber protects the components from the environment. It prevents ice formation and protects against external contamination.
 

The second stage
Compensated second stage for easy and smooth breathing
The XTX purge button is large and easy to operate. It is progressive and offers 2 flow rates. Press on the sides for low flow, useful for controlling the inflation of a parachute. Press on the center for maximum flow, ideal for purging a regulator.
Large venturi flap with soft grip, easy to handle. Its shape limits debris ingress, makes it more resistant to friction and easy to handle.
Sensitivity adjustment knob for performance control
The second stage is made with an additive that limits the formation of bacteria.
Comfo-bite mouthpiece to reduce jaw fatigue.
Heat exchanger (Patented) around the mechanism to evacuate the cold generated by the gas expansion while capturing the calories of the water.
 

Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.
The regulators have been specially cleaned and assembled in our purpose built class 'J' (10,000) Clean Room using oxygen safe components and lubricants and are available in yoke ('A') clamp or DIN fitting.

The XTX50 is for the discerning diver who wants the benefits of a feature-rich regulator at a moderate price. This popular regulator has four medium-pressure ports all mounted on a rotating turret, resulting in optimal hose routing while eliminating sharp bends in the hose.

• Nitrox equipment will be supplied in Europe in accordance with the EN 144-3 and the EN13949 which states that equipment sold in CEE (European Community) countries over 21% and up to 100% will be manufactured with the special M26 fitting.
• Four medium-pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose.
• 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. The regulator is supplied with both sets of exhaust tees.
• Optional 5th port is available for sidemount or twin cylinder set ups.
• Can be converted from a right-handed hose configuration to a left-handed one. 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.
• Suitable for coldwater use (below 10 C / 50 F).
• Compatible with EAN40 out of the box.
