Meco Breathing Air and Oxygen Regulators<br />
8330/8329 Breathing Air/Oxygen Regulators - Hi-flow (5700<br />
CFH/95 CFM) Meco regulator is the ultimate in reliable, field<br />
repairable regulators on the market today. Inlet pressures of up to<br />
3000 psi, and an outlet pressure capability of 550 psi. The 8330 is<br />
perfect for HP standby breathing air while the 8329 is used for oxygen<br />
delivery. These regulators are built to withstand harsh offshore<br />
environments by using brass, stainless steel, teflon and bronze<br />
components throughout.<br />

Broco HVR-4401 Oxygen Regulator<br />
The 2-stage Broco Underwater HVR-4401 regulator<br />
(used with 3/8” I.D. oxygen hose) delivers the high<br />
volume of oxygen required to optimize Ultrathermic<br />
cutting performance. Flows 4400 cu ft per hour.<br />
UL Listed, the HVR-4401 has been designed and<br />
manufactured for ruggedness, ease of operation<br />
and maximum efficiency.<br />
Maximum inlet pressure: 3000 psig<br />
Delivery pressure: 0-350 psig<br />
Weight: 9.0 lb<br />
To Adjust Gas Delivery Pressure for Cutting at Depth:<br />
90 psi requirement at torch end<br />
Depth x 0.445 = ambient pressure<br />
Ambient Pressure + 90 psi Torch Requirement = Regulator Setting<br />
EXAMPLE<br />
Dive of 190 FSW, 190 x 0.445 = 85 psi<br />
85 psi + 90 psi = 175 psi gauge setting topside
