APEKS GX300 REGULATED SUPPLY PRESSURE TABLE
NOTE: The main objective of the regulated supply pressures listed in the table below is to
ensure that a pressure between 8.9 and 10.3 bar above ambient pressure is maintained at the
diver as tested and CE certified.
NOTE: The supply pressures listed in the table below were derived by breathing simulator
trials for optimum performance at each depth using a breathing rate which simulates hard work
(an RMV of 62.5 lpm). They were obtained using a 100 meter [328 ft] umbilical with a minimum
I.D. of 9.5mm [0.375"] with not more than two sections. Use of different size umbilicals will
affect performance.

HP Gas Supply Systems: The GX300 Regulated Supply Pressure Table applies to conventional
surface supply systems providing a regulated gas supply to the diver through an MP umbilical. If a
high pressure (HP) gas supply system is used, the information in the regulated supply pressure table
does not apply. The HP gas supply system will automatically adjust the diver's gas supply pressure
with changes in depth. Always refer to the manufacturer's instructions for the system being used.
