These respirators consist of several key components: a filter or cartridge, a blower, a breathing tube, and a facepiece or hood. The blower pulls ambient air through the filter, which removes contaminants. The purified air is then delivered to the facepiece or hood, providing a continuous flow of clean air. This design not only protects the user from inhaling hazardous substances but also reduces breathing resistance, which is especially helpful during extended use or in physically demanding tasks.
