3M single-unit battery charger can fully charge a discharged battery in approximately 8 hours. LED indicates the status of the charge. It has automatic switch-over to trickle rate mode to prevent overcharging. 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. Charger has trickle charge setting to avoid over charging. 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. 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.
