Air fed mask is out of my price range for now haha I will have to get some of that soap though normal soap does nothing for the smell lol
Better being called names and being a bit uncomfortable/sweaty than a shortened life with CPOD or whatever, wheezing into an oxygen mask is no way to spend your retirement.
Sometimes its the luck of the draw. However if it means making the odds better i would rather wear the ppe.
As for Racal they got taken over by 3m & the airstream was then made by them up until a year ago. There were versions designed specificaly for welding and metalworking. I found it quite comfortable to use with the cooling draft coming down my face & exiting under the chin. Some people coundnt get on with the motor whirring away behind your head but you get used to it. Believe me if you are spending 6 hrs straight grinding grp on a bit boat repair with the dust flying like itchy snow & inches deep on the floor you appreciate a good respirator!
3m now make the versaflow system which has a lightweight headtop fed by air from a belt mounted pump/filter unit, best be sitting down when you look at the prices. Other similar kit is made by sundstrom & martindale. About the cheapest is the Trend airshield but its very poorly balanced.
Axminster tools have just bought a new one out as well.
Another type is an air fed mask (often used by paint sprayers) fed with air from a turbine pump usually placed outside, i was thinking of getting one of these pumps a few years ago for grp laminating but couldnt find a supplier in the uk
