275984 - Miller BreatheAir 2-Person Portable Filtration Box 5ppm Alarm (Canada)

Advanced Respiratory Protection for Canadian Industry

The Miller BreatheAir™ Portable Box (275984) is a high-performance filtration system designed to provide Grade-D breathing air for industrial workers. Engineered specifically to meet Canadian safety standards, this unit features a Carbon Monoxide (CO) monitor set to alarm at 5 ppm, ensuring strict compliance and maximum safety for operators in hazardous environments. This portable solution is essential for applications utilizing Supplied Air Respirators (SAR), such as the Miller C50 system, bridging the gap between standard compressed air and safe, breathable air.

Three-Stage Filtration Technology

To guarantee the delivery of clean air, the BreatheAir™ box utilizes a robust three-stage filtration process:

• Stage 1: Removes 95% of liquids and coarse particulates down to 5.0 microns, protecting the finer filters and the user's respiratory system from bulk contaminants.
• Stage 2: High-efficiency filtration removes 99.99% of fine oil mists and particulates down to 0.01 microns, ensuring the air is free from oily residues common in compressor lines.
• Stage 3: Activated charcoal filtration removes organic vapors, odors, and tastes, providing comfortable and clean air for the user.

Integrated Safety Monitoring

While filtration removes physical contaminants, the integrated CO monitor is the critical safety watchman. It continuously samples the air for Carbon Monoxide. If levels reach the 5 ppm threshold, the unit triggers external warning lights and a loud audible alarm, allowing users to disconnect and evacuate immediately. The monitor is designed for efficiency, featuring a calibration process that takes less than two minutes, significantly reducing maintenance downtime.

Designed for the Field

Weighing in at just 19.7 lbs, this 2-person filtration box is built for mobility. Its rugged case protects internal components from the rigors of daily industrial use, while external filter change indicators eliminate guesswork by visually signaling when maintenance is required. Whether for chemical plants, manufacturing facilities, or confined space operations, the Miller BreatheAir™ box delivers reliable protection.
