I've got a Grizzly G0443 Cyclone Dust Collector with the extended drum, which makes the round collector drum 24" diameter x 27" high, and about 55 gallons. To be clear this is NOT the bag hanging from the filter, but rather the bag that collects the chips as they go through the system. I've gone through the bags that came with it, and Grizzly doesn't seem to have anything specifically for this collector drum.
I'm also not turning up anything for Cyclones that isn't an industrial order 300 at a time.
What do you do to source bags for your cyclone collector?
