Core ACD + Core Octopus

The CORE regulator’s amazing breathing, which is rated as “superior” on the ANSTI breathing machine, coupled with its generous features, at an attractive mid-range price, provides the best value of any regulator offered today. The CORE comes standard with Aqua Lung’s unique, patented, auto-closure device (ACD) which seals water out.

The CORE octopus provides the same great performance as the CORE primary second stage. Thanks to its highly efficient heat exchanger, it is up to the rigors of cold water diving. With its 39” hi-viz yellow hose and front cover, it will be ready to provide life-sustaining air in an out-of-air situation.


The CORE Regulator features:

  • Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the CORE is removed from the cylinder valve

    • This prevents internal lubrication from washing away

    • Safer for elevated percentages of oxygen

  • The balanced diaphragm first stage provides superior, consistent performance

  • The pneumatically-balanced second stage results in smooth, easy breathing

  • Available in yoke (3300 psi / 232 bar max) or din (4350 psi / 300 bar max)

  • The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports

  • Uses parts that are common to other Aqua Lung models for easier servicing

  • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth

  • 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

  • Compatible with EAN 40 new, out of the box

  • Equipped with Aqua Lung’s patented Comfo-bite™ mouthpiece along with a reusable mouthpiece clamp

CORE Octopus features:

  • The CORE octopus is pneumatically-balanced. This results in smooth, easy breathing

  • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth

  • 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

  • Includes 39" yellow hose and yellow front cover
