Shigematsu's supplied-air respirators provide superior protection and ensure easy breathing and are favored in a variety of industrial fields.Gas respirators have limitations depending on the kinds and concentrations of gases. However, supplied-air respirators can be used anywhere irrespective of the airborne contaminant concentrations. Unlike SCBA, supplied-air respirators are lightweight, and there is no risk of the supplied air running out.n Wearing Example (Combination)AL-4NPBFM-204471★Cannot be used where oxygen concentration is less than 19.5%.• Plastic buckle• Facepiece, face shield, and hose length are selectable.• Use together with an air purifier* Other waist belts in the same series are available.
