  • Breather Box® Breathing Air Filtration System

    The Breather Box® is a portable filtration system designed to provide breathable air for a specified number of workers. It works with ANY brand of respirator. The system filters incoming air from a compressor to provide breathing air to respirator users, and it also monitors for CO and/or oxygen. Grade D breathing air is required in industrial applications, and the Breather Box® is an important component in this. 

    Many configurations are available for both field and in-plant applications, some of which are shown here.  Contact us for more options.

    • Flexible.  Comes in 1, 2, 4, or 8 outlet configurations.  And an optional wall-mount is available as well.
    • Rugged.  Designed for field use with a sturdy Pelican® case.
    • Capable.
      • Has three-stage filtration as follows:
        • Particulate/Bulk Liquid Separation

  • Bullard CAB Clean Air Box / Breathing Air System

    The Bullard Clean Air Box (CAB) offers tried-and-true breathing air filtration and carbon monoxide monitoring.  Without the new features on the latest model AirGuard Breathing Air Box, they nonetheless provide required protection, and at a reduced cost.

    With flexible configurations of 1, 2, 4, or 8 outlets at various capacities up to 100 CFM, the CAB Breathing Air Box can support small or large crews.  NOTE:  The actual number of personnel that any breathing air box can support is dictated by the box CFM capacity and the CFM requirements of their respirators, and NOT by the number of outlets on the box.  

    While not required by breathing air standards, adding a dedicated Air Gladiator breathing air filter in-line before the box will extend the life of the more expensive filters inside the box.
