I have a 50-720 that has a 13.25" round opening and 31" tall filter. I can find aftermarket replacements for every other vertical dust collector but this one.
I need a replacement because it was previously used for carbon fiber dust which is very fine and imbedded in the filter bag. When the system is on and I pat the bag you can see a plum of dust come out of it despite multiple attempts at cleaning. I'm now using it for wood and don't want the CF in the air.
Anyone try folding down a bigger one?
