Welding fume extraction
After doing a bit more welding/cutting in the workshop recently, I've realised I definitely need some sort of fume extraction. The plasma cutter in particular generates a huge amount of smoke.
So....
I've got these couple of extractor fans from work that came from an old fume hood that got removed.
Both have the same .55kW motor, but one has a larger impellor (and expanding connection on the outlet) and the other has a smaller impellor and a converging outlet.
Taking a quick look online, the commercial welding fume extractors seem to start at about 1hp (.75kW) and go upwards, so possibly these might be a little on the underpowered side, but at least it would be better than nothing.
Any thoughts on which of those 2 fans is likely to work better running a 150mm inlet hose?
