This lightweight, comfortable respirator hood helps provide head, neck and respiratory protection from pesticide and chemical overspray, lightweight, loose fitting, for use with belt-mounted powered air purifying respirators or supplied air components.
Replacement respirator hood for 3M™ Hood Assemblies H-421 and H-422. 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. Potential benefits include: • 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 faceseal or fit testing • Battery-powered blower pulls the air through the filter resulting in no additional breathing resistance to the wearer
