The Breather Box™ Brochure


The Breather Box

High Performance Portable Grade-D Breathing Air Filtration System

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.


Custom Designed Breather Box™ Options 

  • Clear View Windows
  • Independent Regulators to allow different respirators and lengths of hoses to be used simultaneously
  • Fully Automated Reserve Air Systems
  • Low Pressure Alarms

Airline Monitors


Portable CO Monitoring
Intermittent or Continuous Sampling

This portable airline monitor connects easily to bb50a breathing air filtration source or ambient air pumps and monitors the air for CO content.  The audible alarm (90dbA) and light will activate when the CO level exceeds 10ppm (5ppm Canadian).  External alarm and lights allow for the unit to be used in the closed position and eliminates damage and contamination of the internal components.
