The Core comes standard with Aqua Lung's unique, patented, auto-closure device (ACD) which seals water out. The 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 and is safer for elevated percentages of oxygen. The balanced diaphragm chrome plated marine brass first stage provides superior, consistent performance and the pneumatically-balanced second stage results in smooth, easy breathing.
Available in Yoke with a service pressure of 3300 psi (232 bar) maximum. The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports. The Core uses parts that are common to other Aqua Lung models for easier servicing. The easy-to-grip venturi lever prevents unwanted free-flow 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. The Core regulator is compatible with EAN 40 new, out of the box. Equipped with Aqua Lung's patented Comfo-Bite mouthpiece along with a reusable mouthpiece clamp.
