![]() ![]() 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. ![]() A hull-stop valve should be an integral part of the system as a safety device to shut down the vacuum should a pressure loss occur. It is recommended to use a negative spring biased back pressure differential regulator, such as the Tescom Regulator 26-2912-282A. The regulator is designed to operate with a constant inlet pressure of 65 to 125 psig over chamber pressure.įor chamber depths over 60 FSW, a secondary vacuum regulator must be installed. The demand regulator assembly provides breathing gas on demand (inhalation). The AVOX 80 Pressur Vak II™ is designed to administer oxygen or gas mixtures to a diver or patient in a hyperbaric chamber environment. ![]()
