technical BCD crotch strap is 2” wide

AIR CELLS
JT-30 - 30lb air cell, JT-40 – 40lb air cell, JT-50 – 50lb air cell & JT-65 – 65lb exp. air cell
IST’s air cells’
outer shells are all made from tough 1680D ballistic nylon and inner bladders from TPU coated
nylon. They are made for you to safely take on the toughest dive missions.
For JT-30 single tank (left) and JT-50 twin tank (right) air cells, each has a single inner bladder, and comes
with a single 16” inflator with standard technical elbow connection and an over-pressure exhaust valve to the
front lower left side (when wearing). They have 1 pair of grommets at industry standard 11” apart.

JT-65 is like JT-30 and JT-50 but packed with redundancy features * and more. It has a back up 19” inflator
hose, which is attached to a second (back up) bladder. Each bladder also has 2 over-pressure exhaust valves
for convenience in buoyancy control. The position of the valves and inflators can also be interchanged for a
personalised set-up. There are 3 sets of grommets and each set has 2 holes, are 11” apart. You can fine-tune
your bladder location in relation to the harness and tanks. Lastly, due to its increased size, a parameter
bungee cord wraps around the air cell to restore hydro-dynamics when less / no air is inside the inner bladder
while diving.
* Note: The primary bladder should be used at all time during a dive unless, in the unlike event of
it becoming faulty, ONLY then the redundant (back up) bladder can be used. As to how primary /
redundant bladder is arranged, please consult your technical dive manual and / or instructor.
The rapid exhaust valve automatically
releases gas when the pressure inside
the bladder is 0.17kg/cm² (2.4psi) > the
ambience to protect the bladder from
bursting.
All air cells come with 16” long power
inflator and standard technical elbow
connection (left) except for JT-65, which
back up power inflator is 19” long. There is
a 13” long option (as extra) for those who
prefer a shorter set-up.
