I know that 2 of the big concerns with DC is the filters - not catching fine dust and not having enough surface area to be effieceint.
So I was thinking, what if we just remove the filter? Well more specifically, what about connecting a trash can separator on the out put side of the blower to catch the big stuff, and then vent the remainder of the dust to the outside?
This idea is mostly for low volume home shops. It won't work if you generate mountains of dust.
What do you think?
