Last night I was musing over how to build and where to locate a dust filtration unit to collect air borne dust. I release that it is best to collect it at the source, but sometimes some escape. My thoughts wondered to the low priority (due to cost) of adding a gas furnace to the shop.
I have two locations in the shop that seem to produce fine dust: The area around the dust collector (HF unit with Wynn nano filter) and the area where I do sanding (Ridgid belt/spindle, v-drum, Proformax). I would like to be able to suck air from both areas.
Then it occurred to me that a furnace will have multiple vents for return air.
So, I got to wondering that instead of having a rectangular opening, could I use round pipe of appropriate size and have dual inlets for the same filtration unit? One inlet would nothing but a elbow and vent cover, the other would extend about 12 feet, then an elbow and a short piece of pipe with a vent cover.
What do you think?
