The Air Systems International BB150-CO Breather Box® is the ultimate heavy-duty solution for high-volume, portable Grade-D air filtration. Engineered for maximum air flow, this rugged system provides 150 CFM of filtration capacity to protect larger crews working in demanding industrial environments. It seamlessly converts raw, oil-lubricated compressor air into safe, clean, OSHA-compliant breathing air.
Housed in a virtually indestructible, weather-resistant case, the BB150-CO is built to withstand the harshest field conditions, making it the top choice for large-scale sandblasting operations, industrial tank cleaning, shipyards, and complex hazardous remediation jobs.
Why Choose the BB150-CO?
• Maximum Air Volume: Offers a massive 150 CFM filtration capacity (203 CFM total flow capability) to effortlessly supply high-volume air to multiple respirators, blast hoods, or specialized climate-control vortex tubes.
• Continuous Carbon Monoxide Monitoring: Equipped with a built-in, multi-voltage CO monitor that constantly sniffs the air stream, instantly triggering a piercing 90 dBA audible alarm and bright visual indicators if carbon monoxide exceeds safe limits.
