Air Filtration Panels convert shop air used for pneumatic tools and equipment to clean breathable air. They provide from 1 to 8 airline respirators a portable source of up to 30, 60 or 100 cfm of breathable air from 5-125 psig. The 3-stage filtration system purifies compressed air removing water, oil and particulate contaminants. An optional carbon monoxide monitor, which can be operated in AC or DC mode, activates an audible alarm when the concentration of CO exceeds 10 ppm (set for 5 ppm in Canada). The pressure regulator includes a pressure gauge and adjustment knob with locking ring. An adjustable pressure relief valve protects the CO monitor and respirators in the event of regulator failure. The Carry-Air AC/DC-powered unit is housed in a rugged Pelican case for portability and protection. It includes a support stand for stability and up-right operation. An AC/DC powered Wall-Mount unit is also available. Available with and without CO monitors. Both models meet NIOSH requirements for point-of-attachment
