275985 - Miller BreatheAir 4-Person Portable SAR Filtration Box (10 ppm Alarm)

Protect Your Crew with Clean Air

In the world of professional welding, respiratory safety is not just a regulation—it's a necessity. The Miller BreatheAir™ 4-Person Portable Filtration System (275985) is the ultimate guardian for your team, transforming standard compressed air into safe, Grade-D breathing air. Designed to work seamlessly with Miller's Supplied Air Respirators (SAR), this portable box allows up to four welders to work comfortably under the hood with a constant supply of cool, clean air. By removing contaminants before they reach the welder, you significantly reduce the risk of respiratory illness caused by welding fumes, oil mists, and other shop contaminants.

Reliable CO Monitoring and Alarms

One of the biggest invisible dangers in supplied air systems is Carbon Monoxide (CO). The Miller BreatheAir™ system actively guards against this with a built-in CO monitor. If the CO levels in your air line exceed 10 parts per million (ppm), the box immediately flashes bright warning lights and sounds a loud alarm. This instant feedback allows your team to disconnect and reach safety before dangerous exposure occurs. The system is built tough to withstand the rigors of a welding shop, weighing only 32 lbs for easy portability. Whether you are working in stainless steel fabrication, flux-cored welding, or general manufacturing, this system moves where you move.

Hassle-Free Operation and Maintenance

Miller has designed the BreatheAir™ system to be as user-friendly as possible. You don't need to guess when to change the filters; clear indicators on the cartridges tell you exactly when they are spent. The three-stage filtration ensures that the air doesn't just meet safety standards—it tastes and smells clean, removing the oil and stale odors often associated with compressor air. With an automatic condensation drain to keep the system running dry and efficient, you can focus on laying perfect beads rather than worrying about your air supply. Invest in the Miller 275985 to ensure your crew stays healthy, compliant, and productive.
