350M BIBS Mask and 450M BIBS Mask
Amron International's new 350M BIBS mask and the 450M BIBS mask have the perfect combination of performance, durability and comfort. They were specifically designed to meet the rigorous Norsok U-101 breathing standard and has been successfully performance tested by NUI and validated by DNV. Unlike other BIBS on the market today, these masks are built to withstand the extreme conditions found in a saturation diving environment.
The demand regulator is fully adjustable to allow for easy breathing from surface decompression all the way down to 350 meters pressurized depth for the 350M and 450 meters pressurized depth for the 450M. Diver's comfort was a major consideration so these masks come standard with a comfortable oral nasal and a supportive head strap.
For chamber depths over 99 feet of seawater, a secondary vacuum regulator must be installed (see Tescom Regulator (Part Number: 26-2912-282A). A hull-stop valve should be an integral part of the hyperbaric system; used as a safety device to shut down the vacuum should a pressure loss occur. The vacuum regulator allows the exhaled gases to be carried to the outside of the chamber thereby eliminating oxygen buildup or contamination of the chamber environment.
