Aqua Lung CORE Regulator

  • Sale
  • $ 460.99

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.


·         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
