Guys,

I have an engineer friend who designs dust collectors for wood.

There is some specific information out there very relevant to particulate size.

For a good intro see: http://billpentz.com/woodworking/cyclone/index.cfm

The summary on the above page is a good start, too large to paste into here, but a fairly quick read

But, IIRC, my friend's information is a "quantum level" better in its scientific and health aspects.
