OVERVIEW

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.

FAQ

This specific model (275984) is set to alarm at 5 ppm (parts per million) to meet Canadian safety regulations. The standard US model typically alarms at 10 ppm.

No, this unit does not remove Carbon Monoxide. It filters particulates, mists, and vapors, and *monitors* for CO. If CO is detected, the alarm sounds, and users must disconnect and evacuate to a safe area.

This portable box is designed to support up to two users simultaneously.

When used with a properly maintained compressor, the three-stage filtration system provides Grade-D breathing air.

No, the unit includes the filtration box and power cord. Breathing air hoses and supply hoses are sold separately.

The unit is very portable and weighs approximately 19.7 lbs (net weight).

The unit features external filter change indicators that visually notify you when the filters are loaded and need replacement.

Yes, this box is recommended for use with the C50 SAR system, which pairs with the T94i-R welding helmet.
