Miller adds a hard-hat option to its current Powered Air Purifying Respirator line. The hard hat is paired with Titanium Series auto-darkening welding helmets, which feature exclusive InfoTrack digital lens technology. PAPRs provide excellent respiratory protection from hazardous welding fumes, such as hexavalent chromium, zinc, aluminum and manganese, found in some welding environments. All Miller PAPR units have an Assigned Protection Factor of 25 and are NIOSH 42 CFR 85 certified.
