3M Speedglas Adflo Powered Air Respirator - Complete Unit
Its continuous airflow provides filtered air that takes much of the heat and sweat out of welding. By using the Adflo respirator, you get both increased protection and comfort all day long.
The turbo unit draws air through a spark arrester, pre-filter and particle filter (and gas filter when used) to reduce respiratory hazards. It then feeds the air, via the breathing tube, into the welding shield. The constant flow of filtered air and the comfortable face seal keep contaminated air outside the shield.
The new Adflo unit features Lithium Ion (Li Ion) batteries, which are more than 40% lighter than the NiMH batteries used in the original model. The lighter battery has the same life time as its predecessor and also benefits from a faster partial charge time.
