Air Systems announces new AQM monitor for breathing air equipment
Air Systems International has introduced a new Air Quality Monitor (AQM) for its Breather Box portable filtration units, filtration panels, breathing air monitoring products and high-pressure compressors.
Air Systems described the AQM as a monitor designed to help ensure Grade-D breathing air delivery through measurement of carbon monoxide (CO), oxygen (O2) and dew point levels.
The monitor includes a 3-inch colour digital resistive touchscreen that guides users through monitoring, maintenance and calibration steps.
Features include automatic calibration with guided on-screen instructions, service icons for calibration reminders, sensor replacement and battery life, and a built-in instruction manual accessible through the display.
The system also includes a 120 dBA audible and visual alarm, multi-language support in English, Spanish and French and a universal power supply rated 110 – 230 VAC and 12-20 VDC.
Product specifications, options and transition from legacy monitors
Air Systems confirmed that the standard AQM version is currently available and that an intrinsically safe version has been submitted for review and certification.
From January 1, 2026, all new orders and some back orders are expected to include the new AQM monitor due to a back-order consuming existing legacy monitors.
Legacy monitors are defined as units in a black metal case, with model examples including CO-91, CO2-91, CO91-14LAC, CO-91 PM and CO-91IS series products.
The CO sensor and alarm cannot be disabled, while the O2 alarm can be enabled or disabled and the humidity sensor – dew point – can also be enabled or disabled.
Six AA batteries provide approximately 40 hours of operation, with power options including 12-12 VDC input from vehicles or commonly used cordless tool batteries.
The company is also working on retrofit logistics to install the AQM monitor into existing equipment in the field, including a process allowing products to be sent to the factory in Chesapeake, Virginia for modification.
A limited number of parts will remain available for legacy monitors in the near future, and the O2 sensor supply for legacy models has already been exhausted.
An adaptor – O2-NS-ADPT – is now being used to allow a new sensor – O2-NS – to be fitted in legacy models.
