This NIOSH-approved particulate filter helps provide high efficiency respiratory protection in environments containing particulates. Used with 3M™ GVP Belt-Mounted Powered Air Purifying Respirator Systems. NIOSH-approved high efficiency particulate filter used for GVP systems from 3M for respiratory protection against particulates. 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. Constant flow of air can provide cooling for the worker, resulting in greater comfort for the wearer. Loose-fitting headgear options provide respiratory protection without the need for a tight face-seal or fit testing. Battery-powered blower pulls the air through the filter resulting in no additional breathing resistance to the wearer.
