Quoted from sethbenjamin:I just did a cursory search for “supplied air respirators” and got products that ranged from under $200 to over $1,000.
I’d love to know more about this. I’ve never looked into it and would welcome hearing from someone who knows the subject.
Supplied air respirators are a full face shield respirator that completely covers the face.
They have an air line hook up to it. You connect the air line tube into a rechargeable battery back that clips onto a belt around the waist. The battery pack powers a fan that makes filtered fresh air that is pumped into the mask so you can breathe clean air while spray painting. The air also makes it so the mask never fogs up and it also keeps you cool.
I used mine for spraying busses. I loved it for keeping me cool and also preventing the mask AND my glasses from ever fogging up, esp on hot summer days.
When pish came to shove and I wanted to be done ASAP with the least clean up, I'd just use my carbon filtered respirator mask. This was esp true in the winter time, but in the summer, the supplied air respirator was awesome for keeping you cool and preventing fogging of the mask and glasses.
