Ensure maximum respiratory safety on the jobsite with the Air Systems International BB30-CO Breather Box®. This rugged, portable filtration panel is the industry standard for delivering safe, Grade-D breathing air to up to two workers [0.5, 0.6]. Engineered for harsh industrial environments, it features an integrated, continuous carbon monoxide (CO) monitor and a powerful 3-stage filtration system [0.2, 0.13] that removes 99.99% of contaminants. Whether for hazardous remediation, painting, or confined space entry, the BB30-CO provides reliable peace of mind when lives depend on clean air.

Key Features & Benefits
• 3-Stage Advanced Filtration: Eliminates water, oil, dirt, dust (down to 0.01 micron), and unpleasant organic vapors or odors before the air reaches the user's respirator.
• Continuous CO Monitoring: The built-in monitor constantly tracks carbon monoxide levels, triggering a piercing audible horn and bright visual alarm if levels exceed OSHA thresholds.
• Built for Two Workers: Comes standard with two respirator couplings [0.6] and a robust 48 CFM flow capacity to smoothly support two airline respirators simultaneously.
• Jobsite Ready: Housed in a heavy-duty, Pelican-style weather-proof case that resists impacts, chemicals, and extreme conditions.
• Remote Alarm Capabilities: Features an external auxiliary jack, allowing you to connect remote alarms for workers deep inside confined spaces or noisy areas.
