This core-range regulator, compensated on the first and second stage, represents the DNA of Aqua Lung regulators. It is the safe bet for the next few years. It benefits from patented ACD technology as standard. The first stage is perfectly protected even when the regulator is not under pressure.
The Aqua Lung Core can be serviced every 2 years.

SKU: RQ131112 Category:




• Automatic shut-off device (ACD) – water and ambient pollutants cannot enter the expansion valve as soon as it is removed from the valve.
– The internal components are not polluted and remain perfectly lubricated
– Increased safety during use with oxygenated mixtures.
• The compensated first stage delivers increased and constant performance.
• The compensated second stage offers smooth and easy breathing.
• Available in yoke (232 bar / 3300 psi / max) or DIN (300 bar / 4350 psi / max).
• The first T-shaped stage optimizes the positions of the 4 MP outputs and the 2 HP outputs.
• The use of common parts with other Aqua Lung regulators facilitate maintenance.
• The venturi flap and its easy-to-grip control lever make it easy and quick to stop continuous flow.
• Comes with the patented Aqua Lung Comfobite ™ mouthpiece and a reusable collar.

The Octopus CORE provides the same performance as the second stage of the CORE.
• Pneumatically compensated to be perfectly suited for overcompensated regulators.
• Large, easy-to-use venturi lever reduces any continuous flow rates at the surface and increases depth injection.
• A heat exchanger (patented) which surrounds the seat / valve mechanism, dissipates the cold generated by the expansion of the gas while recovering the heat from the ambient water.
• Thanks to a yellow cover and its 1 m high visibility yellow hose, it is easier to locate in an emergency.
