The Air Systems International BB100-CO Breather Box® is the industry standard for high-capacity portable Grade-D air filtration. Engineered to protect up to 4 workers simultaneously, this rugged, field-tested filtration system converts standard industrial compressor air into safe, clean, OSHA-compliant breathing air.
Housed in a virtually indestructible, weather-resistant Pelican® case, the BB100-CO is ideal for heavy-duty industrial applications, including sandblasting, painting, chemical processing, and hazardous remediation.

Why Choose the BB100-CO?
• High-Capacity Protection: Delivers up to 100 CFM of filtration (123 CFM total flow capacity) to comfortably support up to 4 respirators or supplied-air hoods at once.
• Continuous Carbon Monoxide Monitoring: Features a built-in, multi-voltage CO monitor that continuously analyzes the air stream and sounds a piercing 90 dBA alarm if carbon monoxide levels exceed safety thresholds.
• Advanced 3-Stage Filtration: Achieves a 99.99% filtration efficiency down to 0.01 microns using a progressive particulate, coalescing, and activated charcoal system to remove oil, water, dust, and toxic organic vapors.
• Jobsite Ready & Ultra-Durable: Built into an easy-to-carry, impact-resistant case with external pressure gauges, dual automatic drains on the first two filtration stages, and a remote alarm jack.
