Forced Air Respirators

Anyone using one of these to protect the ole’ lungs? It has a box with a filter and fan that blows air thru a long tube/hose to a sealed face mask. Auto painters use them, and there is another application for welders.

Welders use them to prevent “black lung”, auto body painters use them to keep from breathing in isocyanites that are always present in clear coat vapors and mist.

I’ve used the Hobby Air model when painting cars. Big long tube strapped to me coupled with dragging along air lines for the paint gun. Sucked.
