No, a pre-collector does not catch the fine dust. You should be able to seal
your bottom bag if you have the right band for your unit. If you have a Jet
DC use the new band that has a piece of foam inside of a cloth cover. Using
just the metal band without the foam the bag is hard to seal.

I've installed a 2 HP dust collector for my lathes. It collects
mainly fine dust, which I wanted. On the lower clear bag, I'm having
trouble getting a good seal with the band.
I noticed the dust is really well packed in the bag. Would a pre
collector (garbage can) remove a lot of the dust?
I know a pre collector does catch a lot of chips.

What are your suggestions for finishing my system?
