BB60 Series Breather Box | Air Systems

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. Here is a few of the highlights of the upgraded new Breather Box^®, BB60-CO, with improvements over the BB50-CO unit and designed to fit in the existing portable Breather Box at the same cost.
