i have a blasting booth and a pretty big rig. i have a nova 2000 helmet and a nylon/canvas suit. my old hood was nylon with a head set inside. they run on compressed air and pressurize the hood. no need for a mask . the nylon hood was not too expensive. been a while since i bought it. your going to find out any mask is going to make the job 10 times worse if it is warm at all. i will see if i can find the hood supplier. i think it came from my media supplier.
the one at northern is 150 and is close to the same. it is fed by a hose and belt.
