For reliable and effective airway protection FFP1, FFP2 and FFP3 (10 NPF) against dust, fog, organic vapour, acid gas, ozone and hydrogen fluoride use special particulate respirators 3M. These respirators are equipped with an active carbon layer that provides relief from unpleasant odors and are ideal for welding operations or waste sorting. The lightweight cup design is robust and resistant to crushing, while the convex shape, the soft internal facial, the tightening and the double strap ensure a comfortable fit for different facial conformations. The braided elastic bands, with colour coding, help identify the level of protection offered: yellow for FFP1 (NPF 4), blue for FFP2 (NPF 12) and red for FFP3 (NPF 50). Designed to work perfectly with products 3M for the protection of eyes and hearing.
