The AVOX 801238 Series™ Inhalator incorporates all of the components of the AVOX Pressur Vak II™ with the exception of the face seal and manifold assembly. The AVOX 801238 Series™ 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. The Tescom 26-2912-282A Regulator will suffice. The secondary regulator will limit the pressure differential across the vacuum regulator on the mask.

The AVOX 801238-01 Series™ Inhalator comes complete with Demand and Exhaust Dual Hose Assembly with Quick Disconnects, Demand Regulator Assembly and Exhaust Regulator Assembly.

Warning: The AVOX 801238 Series™ Inhalator with overboard discharge is used for surface decompression of persons in a recompression 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.

  • Are the hose connections on the Amron BIBS mask the same as the Avox hose connections?

    Yes, both the Amron and Avox BIBS Mask connect to same Hansen quick disconnects.  Amron part number 59853-00 for the exhaust quick disconnect and 18969-00 for the oxygen inlet.

  • How often should I clean my BIBS Mask Hose Assembly?
    The frequency of cleaning will vary based on the hours of use. Typically the hoses should be internally cleaned at least every 6 months. They can be cleaned with SaniZide or soap & warm water, rinsed with water, and dried. Some facilities require them to be cleaned to a specific O2 cleaning standard.
