OVER-BALANCED
DIAPHRAGM FIRST STAGE
A Balanced Diaphragm First Stage is the perfect regulator for extreme diving conditions, such
as ice diving or diving in high sediment. The balanced diaphragm first stage design has been
the regulator of choice for many divers who find themselves pushing the envelope. The advanced
“over-balanced” design of Oceanic’s diaphragm first stages provides increased air flow to the
second stage as depth increases, compensating for increased air density and demand at greater depths.
In addition, Oceanic’s Balanced Diaphragm First Stages feature a unique dry Enviro Protection Kit
which completely seals all internal components from the harsh environment. This helps prevent
internal corrosion and contaminant buildup, leading to more consistent performance between
service intervals.
