Topic tags/keywords: dust collection cyclone multicyclone oneida

I’m curious if anybody out there has looked into multi-cyclones as a way to trade a little more horsepower for big reductions in cyclone height. You see them in big commercial shops but I don’t see any for sale that are “small enough” for the hobbyist/small-shop market. I HAVE seen Oneida’s Dust Deputy Multi-Cyclone Kit but it seems like getting 1000 CFM through it would mean cornering the market on shop vacs:

In the same vein, we’ve all heard of Dyson multicyclones but, again, not enough CFM. Apparently he spends so much time cleaning the cat hair out of his living room carpet that he has no time to build a serious cyclone for woodworking. Too bad. Wouldn’t THIS be a cool gizmo to watch sucking up your wood dust?

What I’d love to see is someone who’s tried to hook up, say, multiple Bill-Pentz-style cyclones in parallel to get high efficiency in a low-profile package. All my research turned up on the internet was one or two low-CFM DIY cyclones made out of soda bottles, though, like this one on

Cool, but still not quite what I had in mind.

So, what do you all think? I know a single cyclone is easier and readily available – but it’d be nice to have some options when height is at a premium and this one seems intriguing! Has anyone tried it themselves or had more luck than I did searching the internet?

I have not done anything like that. I would look for a different solution like mounting it outside. it helps with the noise too.

I have a JDS-3100CK… It’s only 86” high.

It’s been great for ~ 6 years.

Have your say...
