The Breather Box® is a portable Grade-D filtration system designed to provide breathing air for a specific number of workers. The system filters incoming air from a compressor to provide respirator users with Grade-D quality air and monitors for CO and/or Oxygen.
The first stage element filters bulk water and particulate and has an auto drain. The second stage coalescing filter eliminates atomized oils, mists, ultra-fine particulates, and has an auto drain. The third stage filter removes organic vapors and odors and has a manual drain. Filter change indicators are standard on all three stages of filtration. Filtration efficiency is 99.99% @ .01 micron. All Breather Boxes® are designed to be used in the upright and closed position to prevent internal contamination.
The standard carbon monoxide (CO) airline monitor operates on disposable 9-volt batteries, 8-16 volt DC, or 115 VAC for continuous air monitoring. An external audible alarm and light signals the workers of high CO content. A remote alarm jack is provided on all models except for Model BB15-CO. Point-of-Attachment (POA) boxes can extend respirator usage beyond 300 feet.
Air Systems International introduced the first portable breathing air filtration system in 1984 that was used in the closed position-the Breather Box®. That product, called the BB50-CO, has been the state of the art for breathing air filtration for over 40 years. Today in 2025, we have improved our breathing air portable breathing filtration unit to meet the demands of the 21st century.
