Sounds about right.Why do you want one machine for both? I'd put a ceiling/wall mount air cleaner in a good spot & have a dedicated 2-stage just for collection if it were me. And the 2-stage I would build out of a single stage & trash can, for the simple fact that you'd barely ever have to empty the actual collector again. I hate dumping that bag. Feels like I need a hazmat suit & vacuum airlock.
