APEKS DB4+ 1st stage

This compact, heavy-duty first stage is the result of combining the proven DS4 platform with MTX technology. 

A robust dry chamber with a reinforced diaphragm prevents ice build-up while protecting the regulator from shock. 
An integral heat exchanger around the diaphragm increases the temperature of the gas inside the first stage.
 The classic shape fits most configurations: single cylinder, dual cylinder and decompression block.

The large heat exchange diaphragm support increases the gas temperature in the first stage for improved cold water performance.

Unique overcompensated diaphragm design: During descent, overcompensation allows air at medium pressure in the hose to flow faster than at ambient pressure. This results in better performance at depth.

The DB4+ 1st stage is the APEKS XL4+ regulator, a compact and lightweight 1st and 2nd stage regulator assembly, suitable for diving in all environments, including cold water. Its design and low weight help to reduce jaw fatigue on long dives. The XL4+ is also an ideal stage regulator, perfect for the exploration diver with a large amount of equipment.

APEKS MTX-R 1st stage with rotating turret and 5th MP port

Combining rugged, military-grade engineering with the super-smooth breathing for which Apeks regulators are renowned, the MTX-R is the regulator that lets you explore more. Like the entire MTX range, the MTX-R withstands continuous flow rates, even in the coldest temperatures.

Can be used in very cold temperatures (below 10°C). The innovative overmoulded end cap, diaphragm and forged body of the first stage ensure optimum thermal performance.

During descent, overcompensation allows air at medium pressure in the hose to flow faster than at ambient pressure. This results in better performance at depth.

Equipped with a forged rotating turret with parallel medium pressure outlets for better hose orientation. The fifth 3/8" UNF medium pressure outlet has a protective cap for when not in use. The HP outlets are angled for optimal hose organization and easy connection of emitters.

Unique over-compensated diaphragm design, as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient air. The result is superior performance at depth.

Go hot, go cold, go deep, go anywhere. Enjoy extreme control with the MTX-R first stage.

APEKS MTX-RC 1st stage with rotating turret and 5th MP port

Apeks XTX 40 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 centre 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.
• Easy-to-grip opening effort control knob keeps the diver in control.
• The second 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.
• A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
