I'm building my DC system from scratch, and I want to implement a Thien separator in my system. For the blower I will be building a housing around a 14" TEK355 DC airfoil powered by a 4.5HP motor. The intake on the airfoil is 9", so I am guessing that I will need a larger than usual separator.
Are there any sizing guidelines or rules for building an effective unit?
Here's what I am thinking so far:
Blower sits right on top of a 16-17" tall separator with a 9" bell mouth sticking in 4.5".
8" ducting, material enters the cyclone with a rectangular injector at the top of the chamber.
Baffle with a 1 1/4" slot, made of thin material and tapered around the slot area.
....
Would I be better off going with like 7" ports? I'm wondering if I build it too big, I'll probably need more flow for the separation than I will have running one tool at a time. I suppose I could just always leave a floor sweep open or something for the CFM.
Should the cyclone spin the same direction as the impeller?
