Works but not greatTuesday, March 15, 2011
I bought this to make my 7600 welding respirator work better. It does a pretty good job: #1 it draws air in from behind me rather than right over the welding area. #2 It improves the respirator's weight balance. By putting the heavy organic vapor / P100 cartridges in back, I'm getting far less strain on my neck during long welding sessions. On the downside: #1. Doing a negative pressure fit test (cover the cartridges and breathe in) is extremely difficult if not impossible. The hoses rotate freely and you can sort of get the cartridges overhead and do your fit test, but it's tough! #2 Side to side head movement is quite restricted.
It fit my respirator and the hoses rotate freely
Make it easier to fit test the respirator with this attachment on.
