The Breather Box portable breathing-air filtration system is designed to filter incoming air from a compressor and deliver it, in Grade-D quality, to respirator users while also providing continuous carbon monoxide monitoring.

Air Systems introduced the state-of-the-art BB50-CO in 1984. Over the past year, the company reviewed several new filter manufacturers and discovered a new filter set capable of removing more moisture than current BB50 filters. After extensive filter testing, Air Systems made the switch and recently launched its new BB60 product line.

Key changes in the new product line include increased filtration capacity in excess of 60 cfm with auto drains in the first two filters; filtration removes particulates at 99.9% and oil at 99.8%; reduced pressure drop on each filter stage with differential pressure indicators on each filter; compact filtration design with higher performance using metal and polymers; each filter uses a polymer bowl locking system (no metal bowl guard like the old filter system); and new filters operate in temperatures from 23 to 140 degrees Fahrenheit (-5 to 60 degrees Celsius). www.airsystems.com
