I have a pre separator, works good, but the super fine dust still goes to the vac tank. I’m over it dumping the tank when it fills up. The dust dropping into the bag, seeing the quantity then just zip tie and cut. So maybe get a tank if you want to do it the hard way or get the bagger, I think the longopacs are @30$ which not sure how many full size bags it can make, but worth it in time savings, dust containment. The pulsebac 1250 sits atop, the only size or bigger to get in my opinion.
