many search and rescue teams diving in water
requiring the added safety and protection of a
full face mask.
EXO Original:
The original EXO Full Face Mask has been in
production for many years. The simple, rugged
design has proven very reliable with a mini-
mum of maintenance. The Original EXO uti-
lizes an inlet tube that directs the incoming gas
across the lens, defogging and ventilating the
mask with each breath. This full face mask best
suits the daily working diver that routinely
works at depths down to 130 FSW in extremely
harsh environmental conditions with minimal
pre and post dive maintenance.
EXO Standard:
The EXO Standard shares many of the features
and components found in the Original EXO.
The demand regulator body has been changed
to allow the use of an oral nasal mask in place of
the inlet tube. The oral nasal mask slightly
improves the breathing performance and speech
intelligibility of various communications sys-
tems. All internal regulator hardware and soft
goods are interchangeable with the EXO Origi-
nal. Like the Original EXO, this mask best suits
the daily working diver that routinely works at
depths down to 130 FSW in extremely harsh
environmental conditions with minimal pre and
post dive maintenance.
EXO Balanced Regulator:
The EXO Balanced Regulator is designed for
deep air diving requiring the highest level of
performance. Tested by the US Navy for scuba
and surface supplied air diving to 190 FSW. Its
low cracking pressure and high flow capability
allow it to sustain a level of performance only
previously achieved by sophisticated and ex-
pensive commercial helmets.
This full face mask is best suited for the techni-
cal/commercial diver that is capable of per-
forming the required routine maintenance. Main-

tenance of this mask is required more frequently
than with the other EXO models, but can be
accomplished economically and in less than 15
minutes using standard EXO adjustment tools
and procedures.
WARNING: Contaminated water
diving operations are extremely hazard-
ous. They should NOT be attempted un-
less all members of the dive team have
been trained for this type of diving. You
must check to ensure that every piece
of the diver's equipment is compatible
with the contamination to be encoun-
tered. If there is the slightest doubt re-
garding what contaminants are in the
water, the diver must NOT dive.
WARNING: Do not dive this mask
in water containing high concentrations
of petroleum based chemicals. Clean the
mask using only mild soap and water.
CAUTION: If the EXO is used in the
surface supplied mode the diver must be
equipped with a proper bailout system
and one way valve. See Chapter 2 of this
manual for a detailed list of the items to
be included in the bailout system.
WARNING: All EXO Masks as sup-
plied from the factory are not intended
for oxygen service or with breathing gas
mixtures with an oxygen content greater
than 23.5%. If the user intends to use this
mask for such service, all parts must be
cleaned for oxygen service, and lubrica-
tion with an oxygen safe lubricant must
be maintained. Only lubricants such as
Krytox or Christo Lube are acceptable
for oxygen service. Use of the mask with
oxygen mixtures above 23.5% by volume
without first preparing it for oxygen ser-
vice may lead to fires or explosions that
could result in serious injury or death.
