Zusammenfassung:A compact respiratory protective device fitted with a mouthpiece or mouthpiece assembly that retracts, pivots or rotates into the depth of the device to reduce size when packed. This reduction in size also permits the depth of the downstream air channel to be increased while still producing a compact device. This increase in the depth of the downstream air channel maximizes the efficiency and capacity of the filter assembly and reduces the inhalation resistance of the device. The reduced breathing resistance enhances usability.
