While air leaks are obviously not good, even after you do fix those leaks don't expect the seperator to get 100 percent of the dust, especially the fine stuff. Even the cyclones that are built for the masses don't get all the dust, especially the fine stuff. In my opinion, a seperator, and or a cyclone is designed to get the big stuff so the blower doesn't have to deal with it, and it cuts down on bag changes due to being full.
Yes, I understand this. And I really appreciate the elegance of the Thien's design as I've tried to make my own cone shaped separators. My dust set up is totally home grown and I am (subjectively) seeing (actually feeing at the exhaust) some issues in air flow reduction due to clogged filters (about 800 sq inches of higher end furnace filters - I don't remember the MERV (spelling?) of the filters). I haven't settled on the overall design so I haven't had a chance to clean everything out and install new filters to see if "tuning" my Thien separator will make a significant difference.
Right now I have a huge cavity in front of 800 sq inches of flat filters. I was going to put my separator in there, but the dimensions of the "let's quickly put a Thien garbage can separator together to see if it really works" exceeded that of the cavity. The cavity is about 2x3x4 feet. Any suggestions would be appreciated (i.e. put a second smaller Thien separator in there, two tandem Thien separators in the cavity and get rid of the big one, where to get a 2x2 foot garbage can, ect...)
