275970 - Miller BreatheAir 4-Person Stationary Filtration Panel with CO Monitor

Advanced Respiratory Protection for Industrial Environments

The Miller BreatheAir™ Panel (275970) is a high-capacity, stationary filtration system designed to provide Grade-D breathing air for up to four operators simultaneously. Engineered for heavy-duty industrial applications, this wall-mounted unit serves as a critical safety barrier between standard compressed air lines and the welder's respiratory equipment. By utilizing a sophisticated three-stage filtration process, the system effectively removes 95% of liquids and particulates in the first stage, 99.99% of fine oil mists in the second stage, and organic vapors, odors, and tastes in the third stage. This ensures that the air reaching the user is clean, safe, and comfortable to breathe.

Safety is paramount in the design of the BreatheAir™ system. It features an integrated Carbon Monoxide (CO) monitor that continuously samples the air supply. If CO levels exceed the OSHA threshold of 10 parts per million (ppm), the unit triggers both external warning lights and a loud audible alarm, allowing users to react immediately to hazardous conditions. The monitor is designed for efficiency, requiring less than two minutes for calibration, which significantly reduces maintenance downtime.

Operational efficiency is further enhanced by the unit's user-friendly maintenance features. Each of the three filter cartridges is equipped with a clear change indicator, eliminating guesswork regarding filter life and ensuring optimal performance. An automatic condensation drain prevents moisture buildup, extending the longevity of the filtration media. With a flow capacity of 123 CFM, this 4-person panel is robust enough to support multiple Supplied Air Respirators (SAR) without compromising pressure or flow, making it an ideal solution for manufacturing, fabrication, and confined space operations.
