| The Legend ACD™
regulator series incorporates a proprietary
over-balanced diaphragm first stage design coupled
with a high performance balanced second stage. The
over-balanced first stage achieves unprecedented
performance by increasing your air supply the deeper
you go. The balanced adjustable second stage reduces
breathing resistance to near zero with a lightweight
balanced valve seat designed to respond
instantaneously to the slightest inhalation. The
Legend ACD regulator series is the best performing
regulator Aqua Lung has ever offered. Legendary
performance from Aqua Lung: a tradition for 60
years. * Compatible with EAN 40 right out of the box * Din adapter Option The Legend ACD over-balanced diaphragm first stage combines the reliability of a completely sealed unit with the ease of breathing and quality construction common to all Aqua Lung Legend regulators. The Legend ACD second stage is a pneumatically balanced design that does not require diver adjustment. This is reliability and simplicity at its best! The Legend second stage is matched exclusively with the Legend ACD over-balanced diaphragm first stage. Auto-Closure
Device (ACD) seals the regulator’s inlet
fitting, both Yoke and DIN, as soon as the regulator
is removed from the cylinder valve.
The new ACD feature coupled with the
environmental dry chamber, results in a first stage
that is completely sealed off from the environment. Over-balanced diaphragm design delivers superior
breathing performance even at increased depths Environmentally sealed dry chamber helps resist
freezing and keeps the internal mechanism clean and
dry Inhalation adjustment feature permits diver to control breathing gas delivery under a variety of diving conditions |
