re: Sure...
I find it a bit funny that you don't get my subject heading but Ed does.
Anyway sorry to see your mad at me instead of willing to look for engineering solutions to the problem.
The first thing we need to do is examine the dust not list some similar solutions that don't take the actual problem into consideration.
Like for example: where does the collected dust go in your magnetic bearings traps? Also in these bearings what happens to the electrostatically repelled dust and the non magnetic dust? I think they grind your machines bearings.
