Speedglas Adflo PAPR 9100 FX-Air 36-1101-00SW
Takes a little getting used to, but definitely helps with the smoke and grinding debris.
ProsDefinitely provides a great flow of fresh air and has a surprisingly long battery life.
ConsHeavy and a bit cumbersome, there is no just throw the hood on and make a quick weld. Wouldn't throw out the old hood if it's a quick fab to do, takes to much time to put this unit on and do a quick fab up. But great if youre going to be there a while.
