I've just returned from visiting a wood worker who shows all the symptoms of the problems that fine dust hanging in the air of the workshop produces, both in the shop, and in himself.
He mentioned that he had recently seen in a UK trade fair an electrostatic precipitator for dust removal. We both know that this is an oldish idea, but it seems to have resurfaced in the workshop environment.
Has anyone come across this recently, or has any ideas about the possibilities of using this.
I would emphasise that this would be for the removal of sub-micron sized dust particles, the bits that hang in the air for days and cause most of the problems.
We had a quick brainstorming session, and our two heads managed to come up with an idea for how to produce a diy version, but other input would be welcome.
