Avox 801238 Series Oxygen BIBS Mask System with First Stage Pressure Reducing Regulator without Microphone Assembly

The Avox 801238 Series Oxygen Mask with overboard discharge provides control for the administration of oxygen or gas mixtures without affecting the chamber environment by exhausting the exhaled gases out of the chamber. In most instances the vacuum system is the differential pressure between the inside and outside of the chamber. Breathing gas is reduced to approximately 65 psig to 125 psig above ambient pressure. The low pressure gas flows through a hose to the demand regulator. The exhalation is removed through the vacuum regulator and exhaust hose.

For a pressure differential in excess of 60 FSW, a second vacuum regulator must be installed between the hose and chamber wall. See Tescom 26-2912-282A in Regulator Section of the Amron web site. The secondary regulator will limit the pressure differential across the vacuum regulator on the mask.

The Avox 801238 Series Oxygen Mask comes complete with Demand and Exhaust Hose with Plugs and Quick Disconnects, Demand Regulator, Exhaust Regulator and optional First Stage Regulator.

Warning: The Avox Model 801238 Oxygen Mask with overboard discharge is used for surface decompression of persons in a compression chamber and is not for use underwater. The mask may also be used in other applications where overboard discharge of the user's exhalation is desired.
