I'm trying figure out how to design a 4'x8' downdraft table. I have a 3900 CFM / 2" S.P. blower that I will use. I want to be able to cut small pieces without needing to cover the unused area of the table to capture the smoke. I know large tables are zoned, but a lot of companies offer smaller tables that are not zoned and they claim there is no need to cover unused areas of the table.
Obviously, I can just have one suction hole at the end of the table. I need a design that distributes the suction across the entire cutting area. I'm open to any and all ideas. Pictures would be great!

PFD, Check out this thread, it has just about what you're looking for... 3900 CFM is plenty with a 20" duct.. I'm not sure about the "2" S.P. Blower."
You marry into the PlasmaCam family and must accept the fact your software and hardware are proprietary. It's a for better or for worse engagement with overwhelming security. PlasmaCam controls the computer, table, hardware to their advantage IMO.
