The Avox 801238 Original Inhalator 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 Original Inhalator 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 Original Inhalator 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.

Product FAQ's

Ask a Question

  • What is the depth rating for the Avox 801238 Series BIBS Mask?

    As many of you know, the Avox 801238 Series BIBS Mask has been in the industry since the late 1960's / early 1970's.  This BIBS system has been used worldwide at a variety of depths.   However, there is no official documentation to support a "rated" depth.  Amron recommends the Avox 801238 Series BIBS Mask to perform at depths up to 100 Meters of Sea Water (MSW).

    If your situation requires testing certifications or DNV approval, we recommend the Amron 350M and 450M BIBS Masks. Both masks have been tested and certified by NUI to depths of 350 MSW and 450 MSW respectively.

  • Can the AVOX Oxygen Mask hoses and diaphragms be cleaned using a sterilizing machine? The sterilizing machine operates at 212°F (100°C).

    The AVOX Oxygen Mask was not designed to be cleaned by a sterilizing machine. We recommend using SaniZide-Plus to disinfect your AVOX Inhalator. You can also clean all metal and non-metal parts with nonionic detergent such as “Ivory Liquid” and warm water (110 °F maximum). Rinse with clear water and dry completely before storing or using. 

    The information provided should be used as a guideline only. Every company should have their own procedures in place for cleaning and/or disinfecting safety equipment used in oxygen and breathing environments.
