i have noticed lately my lower bag was getting more scrubbing and more dust lately, then i realized my filter was covered in fines. but i use my tools a lot, minimum 24 hours a week and it took about a year to need a cleaning.

im changing shops soon out of my garage to an actual woodshop for business, eventually i will go larger blower etc but for now i am trying to maximize my hf thien top hat baffle system.

any thoughts would be great. TIA!

I found a new impeller in a thread for my dust collector according to a thread on hear, its the grizzly 12 3/4" x 3 1/2" part number P1028Z2010 and they happened to be on back order till may but june or july is more likely according to the lady at grizzly. They also happen to be 110 bucks plus shipping and tax! They were only 80 dollars not too long ago according to that thread.

So i have a couple of questions, since there were so many different versions of the hf dc, how do i know if it will fit first off? My arbor looks to be 3/4". I have a Seco 2hp DC that has a 3phase motor unfortunately:-(  as well with a plastic 12" Impeller but the arbor looks to be 13/16" with a different arbor key so no dice.

Is there anybody else who has a larger Impeller that fits the HF DC? And hopefully it wont costs as much as the grizzly?

Or is there anywhere is to get the grizzly impeller for cheaper?

I just built my seperator with 6" ports so I wouldn't have to build another one in the future and I would like as much air flow as posible, however, its doing really well with my wimpy 10" Impeller. Hehe Any help would be appreciated.
