High-altitude upgrade for PAPR by 3M

Reliable protection and comfort for welders comes standard with the 3M™ Adflo™ Powered Air Purifying Respirator System (PAPR). The 3M welding PAPR now features a lithium ion battery — reducing the overall weight of the respiratory system by approximately 20 percent — and has an optional high-altitude upgrade for welders working at altitudes of up to 10,000 ft.
