Our EZ Air Flex Grinding/Welding Supplied Air Respirator (SAR) is intended for industrial applications where combined respiratory, eye and face protection are required. This welding helmet features a durable flip-up visor to expose a grind shield below that maintains respiratory protection while workers can continue grinding or inspecting welds. It is a system that provides a constant supply of fresh air over the user’s face. At an APF level of 25, it creates an optimal protective pressure inside the respirator head top keeping away particulates (dust, steel, manganese, stainless steel, chromium, galvanized steel, cadmium, lead and ozone).  Complies with ANSI Z87.1+ for face-shield/eye protection. CE certified. NIOSH approved
