275983 - Miller BreatheAir Portable Box 2-Person Filtration System, 49 CFM, 10ppm Alarm

Breathe Easy with Miller's Advanced Filtration

Welding in confined spaces or areas with poor ventilation presents significant health risks, but the Miller 275983 BreatheAir Portable Box Filtration System offers a robust solution for professional welders. Designed to support up to two welders simultaneously, this portable unit takes compressed air and scrubs it clean, delivering Grade-D breathing air directly to your supplied air respirator. Whether you are working with stainless steel, flux-cored wire, or in heavy fabrication, ensuring a supply of clean, breathable air is paramount to long-term health and immediate comfort.

The BreatheAir system doesn't just filter air; it transforms your working environment. When paired with Miller's C50 SAR regulator (sold separately), the air delivered to your helmet can be up to 50 degrees Fahrenheit cooler than the surrounding ambient air. This cooling effect significantly reduces heat stress and fatigue, allowing you to maintain focus and weld for longer periods without discomfort. The system's three-stage filtration removes 99.99% of oil mists and particulates as small as 0.01 microns, as well as odors and tastes, so the air you breathe feels fresh and clean, even in the grimiest shops.

Miller has prioritized safety and ease of use in this design. The integrated Carbon Monoxide monitor is a lifesaver, literally. It constantly checks the air for dangerous CO levels. If the concentration hits 10 ppm, the box flashes bright warning lights and sounds an alarm, giving you instant warning to get to safety. You don't need to guess when to change filters either; clear indicators on the unit tell you exactly when the cartridges are spent. The automatic condensation drain handles moisture buildup, so you don't have to constantly monitor the unit during a shift.

Weighing in at just 23 pounds, this "briefcase" style filtration box is easy to carry from truck to site. It is built with Miller's legendary durability to withstand the knocks and drops of industrial life. Setup is quick, with standard 1/2-inch connections, meaning you can get to work faster. Protect your lungs and improve your workday with the reliability of the Miller BreatheAir system.
