Don't understand the above, why extraction? if you would like to use a mask
would it not be better to blow clean air into your helmet which could vent
freely into the workspace around you. A low pressure centifugal blower of
almost any old sort would do tho for preference I would steer clear of the
vacuum cleaner type that pulls its air thru the motor and presumably gets a
good helping of ozone from the sparking com.
I use diving air and a firemans breathing helmet but thats a bit over the top
really its just that I still have my old 4000psi diving compressor kicking
around from way back when. Ron S No33.
