I just finished running all the 6" duct work in my shop, and as I look at these two cyclones, the larger is rated for 3-5hp blowers, and the smaller for 1-3hp. Mine is a 2hp. I don't ever see going above 3. So, the smaller cyclone should work.
Problem is, it has a 5" inlet and a 6" outlet, whereas the XL has a 6" in and 6" out. I really don't want to constrict down to 5", but I would have to pay an additional $70 or so just to have a 6" inlet. That seems crazy.
I considered buying the smaller one and modifying it, but at the moment I am cringing at that thought.
Any suggestions?
