Aqualung Core Regulator, DIN

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 Aqualung'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 DIN with a service pressure of 300 bars (4350 psi) 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 Aqualung 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 Aqualung's patented Comfo-Bite mouthpiece along with a reusable mouthpiece clamp. The regulator weighs 24.2 oz. (685 g) and comes with a 28.7" (73cm) low pressure 3/8" threaded hose and owner's manual.
