276166 - Miller BreatheAir 2-Person CO Monitor and Filtration Box

Advanced Respiratory Protection and Monitoring

The Miller BreatheAir™ Carbon Monoxide Monitor Box (SKU: 276166) is a critical component for industrial supplied air respirator (SAR) systems, specifically designed to work with the Miller C50 SAR system. This unit functions as a dual-purpose safety device: it filters compressed air to meet Grade-D breathing standards and continuously monitors the air for dangerous levels of Carbon Monoxide (CO). Engineered for industrial environments, the box features a robust 49 CFM airflow capacity, sufficient to support two operators simultaneously, making it an efficient solution for team-based welding or fabrication operations.

Three-Stage Filtration and Grade-D Compliance

To ensure the safety and health of operators, the BreatheAir™ system utilizes a three-stage filtration process. This rigorous filtration removes particulates, moisture, and oil mists from the incoming air supply, delivering clean, breathable air that meets strict industry standards. The unit is equipped with clear filter change indicators that visually notify maintenance personnel when elements need replacement. This feature eliminates guesswork, ensures consistent performance, and prevents the degradation of air quality due to saturated filters.

Integrated CO Monitoring and Alarms

Carbon Monoxide is a colorless, odorless gas that poses a significant threat in industrial settings. The Miller 276166 includes a built-in CO monitor calibrated to trigger an alarm at 10 PPM (Parts Per Million). Safety is reinforced through external warning lights and audible alarms that provide immediate notification if CO levels spike, allowing users to react quickly and evacuate or disconnect. The monitor is designed for operational efficiency, featuring a quick calibration process that takes less than two minutes, significantly reducing downtime during setup or routine checks.

Durable Industrial Design

Constructed to withstand the rigors of heavy-duty welding environments, the monitor box is housed in a durable casing measuring 18.75 inches in length and weighing 21 pounds. Its portability allows it to be positioned near the work area while maintaining a connection to the main air supply. Backed by Miller's 1-Year Warranty, this filtration and monitoring system is an essential investment for facilities prioritizing respiratory safety and OSHA compliance.
