Amron International 350M BIBS Mask

SKU: 00838c4c2624 Categories: , , , ,


Amron International’s new 350M BIBS mask is the perfect combination of performance, durability and comfort. The Amron 350M BIBS Mask was 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, Amron’s 350M BIBS Mask is built to withstand the extreme conditions found in a saturation diving environment.

The Amron 350M BIBS Mask demand regulator is fully adjustable to allow for easy breathing from surface decompression all the way down to 350 meters pressurized depth. Diver’s comfort was a major consideration so the 350M BIBS Mask comes 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.
