Allegro 9875-40 Five-Worker Wall-Air Filter Panel with AC/DC CO Monitor
Allegro's Air Filtration Panels are the industry standard in multi-worker air purification. The 3-stage filtration system removes harmful contaminants to keep your workers safe! All models meet NIOSH requirements for point-of-attachment. This unit includes a carbon monoxide monitor, which can be operated in AC or DC mode. It activates an audible alarm when the concentration of CO exceeds 10 ppm (can be set for 5 ppm in Canada).
