Use the 3M mask for hand and machine grinding 8822/8812 for comfortable protection when drilling and sawing as well as hand and machine grinding. Our respirator with inhalation valve offers protection against medium exposure to fine dust as well as oil or water vapours, which typically occur during employees working with cement, wood and steel. Equipped with a durable, dimensionally stable inner shell and convex shape, the lightweight design with double strapping has a nose clip with foam padding that provides a comfortable and secure fit for a wide range of face sizes. The 3M Cool Flow valve removes exhaled air and thus counteracts heat build-up in the respirator.
