I need the hive mind’s help again with a dust collection question.

This past weekend a guy who was moving offered me his Super Dust Deputy XL kit (including dust bin and long run of 6” hose) for $100. The deal was too good to pass up, since I figured I could sell it for more if I can’t use it myself.

Currently, I have a HF DC with a Super Dust Deputy connected to a short trunk of 4” PVC that is branched out with gates and 4” hose to my TS, BS, planer and jointer. The setup does a reasonable job with the visible chips/dust, but I know I’ll need to upgrade to a better DC system at some point in the future.

My question: Can I swap out my 4” super dust deputy for the 6” XL (by just reducing the 6” port to 4” coming out of the cyclone)? I’d like to keep the XL, since I could use it when I upgrade to a larger DC, but I’m worried that the larger cyclone will kill the performance of the HF DC. Thoughts?

I believe the larger cyclone will have an adverse effect. The XL is recommended more for 3-5hp collectors .

If you call or email Oneida, they should be able to help with an answer.

The larger SDD XL cyclone will not hurt the airflow performance of the dust collector. It will have LESS loss than the smaller SDD. In general, loss varies inversely with the fourth power of scale for similar geometries. Based on that you might expect the XL to have about one third the pressure drop of the SDD at the same flow rate.

Your separation performance may suffer a bit, but with 4” hose on the inlet I doubt that you’ll see much difference in either separation or airflow.

There are probably some things you can do to optimize what you have. If you’re interested, post a pic of your current setup and we can discuss it.

Complete with years of testing, and engineering included in the answer.

That said I agree the XL is for 3 to 5HP machines, per their advertising, so it may not function to it’s capacity on your smaller unit. Probably will tell you to keep the HF on the current set up. But do let us know what they say.

No doubt a bigger blower and a better brand would be a good thing, but it will work with what you’ve got. How efficiently I can’t say, but it will suck and chips will be in the bucket.

FYI I’m running the SDD on a 1 1/2 HP blower with 6” ducts and it works. I know, it’s not supposed to, but when Inran my new ductwork I couldn’t find a 3hp blower (thanks PennState!) and my “temporary” blower has been there 3 years.

5HP ClearVue is coming soon, tho.

@Dave I’d be more concerned about 4” pipe. Change that over to 6” and you’ll be amazed at the difference, and yes, with that blower.

@clagwell, albeit above my head, your response has encouraged me to give the XL a try. I’ve got a cheap anemometer, so I can do some basic measurements and report back.

And @Robert, although it is hard to submit to a public message board, my 4” hose looks so small now next to the larger 6” version. A quick glance at the comparison makes clear why hose radius has such a huge impact on CFM.

Do you think if I create a main trunk with the 6” hose, but leave the 3-5ft 4” connections to the tools I will still see a meaningful difference?

I used a “6 Dust Deputy on a 2 HP Delta DIY DC it worked fine. I just sold it, mostly because of the footprint. Between the cyclone, the dust barrel, and the pleated filter canister I lost about 6’ x 2’ x 7’ of my shop to the behemoth. Take a look at the manifold if you want to see how I had it piped up.

That was a heck of a setup. I particularly like the clear contraption you built to join all the PVC. You have a video of it in action? I’d love to see the chips and dust flying through there.

Have your say...
