3M face-mounted powered air purifying respirators may increase wearer productivity without the need to wear a motorized blower unit at the waist. Powered Air Purifying Respirators (PAPR) are motorized systems powered by a battery pack which draw air through a filter or cartridge to provide respiratory protection to the wearer. The blower unit can be mounted on the waist, face, or head, depending on the system selected. Certain PAPR systems provide a higher level of respiratory protection than non-powered air filtering respirators. Constant flow of air can provide cooling for the worker, resulting in greater comfort for the wearer. Battery-powered blower pulls the air through the filter resulting in no additional breathing resistance to the wearer. The 3M Powerflow system delivers a minimum of 4cfm when used with the filter. It uses the popular 6000 Series face piece and its faceshield meets High Impact Requirements of ANSI Z87.1-2003. The complete system includes the medium full face piece, 6800DIN, motor blower unit, battery pack, and flow indicator. Approved for use with high efficiency particulate filter only. Up to eight hours of battery service. Lightweight and well-balanced. Ideal for lead, asbestos, mold and other hazardous particulates.
