The ESAB Savage A40 PAPR helmet with Powered Air Purifying Respirator (PAPR) technology is designed for situations where welding fumes and particulates are a concern, such as for some cored wires, working in confined or poorly ventilated spaces, and for protecting operators from hexavalent chromium fumes, which are generated from stainless steel, chrome alloys, and chrome-coated metals.

The unit has three settings that adjust airflow between 170 and 230 l/min to suit the environment and application. It operates at 70 dBA and features a high-capacity, lithium-ion rechargeable battery that offers up to 8 hours of performance between charges, the company says.
