-Gas supply system capable of supplying 4.5
acfm (127.4 BL/min) to the side block assembly
at depth.
-Temperature limitations: Use at water tempera-
tures below 36
o
F (2
o
C) requires use of hot water
shroud and hot water.
The umbilical assembly should be composed of
good quality diving hose that meets industry stan-
dards. Generally, gas hose will be married to the
communications wire, pneumofathometer hose,
and strength member in a manner that will allow
the strength member to receive all the strain.
There are also good quality umbilicals available
that are assembled at the factory using a twisted
method which does not require marrying. Regard-
less of the system used, the umbilical is the divers
life line and should always be of excellent qual-
ity and maintained carefully.
* This assembly has not been tested for CE
compliance. Hooded face masks should NOT be
used for diving in contaminated water situations.
The double exhaust is provided for the masks for
use during jetting operations. It has been found
that the use of a double exhaust assembly can
help in the prevention of inversion of the exhaust
valve during heavy jetting operations.
The diving control station can be at the surface, in
a diving bell, or out of a submerged habitat. The
diving control station is the center of the air/gas
supply, communications with the diver, and div-
ing procedures.
DANGER: Decompression diving
always involves the risk of decompres-
sion sickness. Omitted decompression
due to loss of gas supply or other acci-
dents can cause serious injury or death.
Use of a KMB 18/28 mask cannot prevent
this type of injury.
WARNING: High pressure regula-
tors and associated piping systems for
surface supplied diving with Kirby Mor-
gan helmets and masks must be capable
of delivering a minimum of 4.5 acfm to the
diver at depth. Only systems that can
deliver this required gas flow should be
used. The use of standard SCUBA style
regulators stationed top side is unac-
ceptable as there is no provision for ad-
justing the intermediate pressure sup-
plied to the diver. This can create a dan-
gerous situation where the diver may not
receive an adequate supply of air. Only
regulators which allow a variable setting
for intermediate pressure should be used
for umbilical diving.
Many of the parts on the Kirby Morgan Band
Mask (KMB 18A/B
)
are interchangeable with
our SuperLite Helmets, and the Kirby-Morgan
Band Mask 28. This helps keep inventory costs
low for diving companies and independent divers.
The KMB 28 has a durable injection molded
plastic frame (17) rather than a fiberglass frame
as found in the KMB 18A/B.
The KMB 28 uses the SuperFlow regulator, the
KMB 18 uses the large tube SuperFlow 350
regulator.
