The Air Systems International BB15-CO Breather Box® is the ideal compact solution for single-worker Grade-D air filtration. Engineered for maximum portability without sacrificing safety, this lightweight system provides 15 CFM of dedicated filtration capacity to protect an individual worker in the field. It efficiently converts standard industrial compressor air into safe, clean, OSHA-compliant breathing air.
Housed in a rugged, impact-resistant, and weather-sealed case, the BB15-CO is the top choice for mobile technicians, localized paint booths, small-scale remediation, and solo maintenance tasks where a full-sized multi-worker manifold isn't necessary.
Why Choose the BB15-CO?
• Optimized Solo Protection: Delivers a dedicated 15 CFM filtration capacity (48 CFM total flow capability), providing the perfect volume of air for a single supplied-air respirator or tight-fitting hood.
• Continuous Carbon Monoxide Monitoring: Features Air Systems' trusted, built-in CO monitor that continuously samples the air stream, sounding a piercing 90 dBA alarm if carbon monoxide levels exceed safety thresholds.
• Ultra-Portable & Lightweight Design: The most compact unit in the Breather Box family, making it easy to carry around tight jobsites, climb ladders, or store in the back of a service truck.
• Advanced 3-Stage Purification: Delivers 99.99% filtration efficiency down to 0.01 microns. The progressive system effectively removes bulk water, oil mists, fine particulates, and unpleasant organic vapors or odors.
• Complete Pressure Control: Equipped with a built-in, adjustable pressure regulator and external pressure gauge, allowing the operator to safely dial in and monitor the exact PSI required by their respirator.
