Our EZ Air Powered Air Purifying Respirator (PAPR) with X54V lens is a complete particulate system intended for industrial applications where combined respiratory, eye and face protection is required. It is a motorized, Lithium-ion battery operated system that provides a constant supply of fresh, filtered air over the users face. At an APF level of 25, it creates an optimal protective pressure inside the respirator head top keeping away particulates (dust, steel, manganese, stainless steel, chromium, galvanized steel, cadmium, lead, and ozone*). Recommended applications are welding, assembly, facility maintenance, grinding, machine operations, painting, and sanding. Suggested industries include automotive, food and beverage, general manufacturing, metal production and fabrication, military maintenance, repair and operation (MRO) and transportation. Complies with ANSI Z87.1+ for face-shield/eye protection. NIOSH approved.
