3M Adflo HD Series Powered Air Purifying Respirators

The 3M Adflo HD Series powered air-purifying respirator (PAPR) is a heavy-duty model delivering added features and improved performance compared to its predecessor.

Featuring a slim, robust system designed specifically for welders, the series comes with a lightweight, heavy-duty battery (40% lighter than the previous model), which can extend battery operating time to 12 h. This means workers can gain an extra 4 h over standard systems. The powered air-purifying respirator also offers a rapid charge function, which allows the welder to charge the heavy-duty battery from 0 to 80% capacity in approximately 1 h.

The series is available with a range of 3M Speedglas welding helmets, including the 9100XXi Air, -FX Air and -MP Air. It is also possible for Adflo customers to upgrade to the lighter HD system with rapid charge by purchasing an upgrade kit that includes the HD battery pack and charger.
