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% at 0.01 micron. All Breather Boxes® are designed to be used in the upright and closed position to prevent internal contamination.
