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
