If this is redundunt, my apologies

I converted my Grizzly DC to an Oneida cyclone with a $200 filter and clear plastic bag under the filter. The system isn’t complete as I haven’t done much plumbing yet because finding pipeing and fittings that mate to each other is becoming a real chore.
That however is not the issue – When I turn it on and collect debris I notice a serious whirlpool effect in the plastic bag – is this normal ?
I did notice that chips and larger things are being deposited in the catch barrel under the cyclone and a LARGE amount of dust is being gathered in the plastic bag.
Is this what is supposed to happen ?
It seems this would be ideal because the filter would last longer between cleanings but nobody ever talked about the cyclone in the bag -

Yes, I think it is normal. I don’t have the cyclone yet, I will be installing it near my planer and 19/38 sander. But I added the vortex cone to my jet dc, and the chips and dust look like something from the wizard of oz. Spinning around nicely. And the pleated filter stays much cleaner.

What you describe is what I think is normal operation, but to be sure I found this on the Oneida web site:

The way I would look at it is – if it works, stick with it.

Hi Dick. I have that Dust Deputy over a 30 gallon barrel and the swirling happens in the cone on top and then it drops in the barrel. I don’t know if it is still swirling in the barrel because it is opaque, but when I first put it on there and turned on the shop vac powering it, it sucked the side of the barrel in. I had tp install wood rings to keep the barrel from collapsing!

I think yours will be fine if the dirt wind up in the bag!

cheers, Jim

Thanks guys
It appears that all is good, I just never heard any talk about swirling in the plastic bag under the filter. I’m pretty sure about one thing tho – there’s no dust getting in the air.
I think it’s been worth all the aggravation and $$$$ getting this set up
