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.

The BB100- CO has a Grade-D filtration, 123 CFM, with a CO monitor and alarms and 4 Hansen respirator couplings
