3M 4277 Respirator Half Mask ABE1 P3
The 3M 4277 respirator assures protection against acid gases, vapours and particulates, including ammonia and solvents. As with all the 4000 series masks, the innovative single-piece design comfortably integrates twin inhalation valves into the main body of the mask, removing the need for additional filters. As a result, this product is always ready and simple to use, avoiding operator assembly errors. In addition, the central parabolic valve reduces breathing resistance and ensures the mask-user does not overheat.
