I currently am using a Thein separator on my dust collector and am trying to learn if I change to a Super Dust Deputy cyclone if I would gain anything such as improved suction and/or better fine dust separation? Does anyone have any experience in this regard ?

I had a Thien style separator and went to a SDD. Unfortunately, I went from a shop vac to a 2hp DC, so I can only compare apples to oranges. It is my opinion, based solely on my personal experience and observation, is that the SDD is a significant upgrade.

I have the super dust deputy on my dust collector and it works great. There is plenty of suction at the farthest point. It will suck the board tight to the radial arm saw fence. To get to that point there is four elbows and a total of 35 feet of 4” pipe. I also have a dust deputy attached to a shop vac and it works great as well.

I just ordered a Wynn filter to replace the felt bag on my HF dust collector. Was going to build a Thein separator like I have seen so many LJs post. Now I am wondering if I should go the Super Dust Deputy route instead.

Get the super dust deputy. I get virtually no dust going to the dust collector, it all drops in the barrel.

I’ve got the Wynn filter on my DC already. My current separator does a really good job at handling both the shavings and dust as I get virtually no measurable dust in the bag unless I accidently overfill my separator collection can. My DC is an older Delta 1-1/2 unit. I am also running 4” pvc pipe to my machines. My question really is: Would replacing my current Thein design top hat separator with a Super Dust Deputy produce more noticeable suction?

I have neither, but I’ve followed a lot of postings on the subject. I think that the bottom line is “not much difference” on either separation efficiency or insertion loss (loss of suction).

Both cause significant insertion loss. Since most DCs don’t have enough suction to clear the small particles that cause health issues, neither should be used. It would be better to forgo the extra separation, which means you need to clean the filter more often, and get more suction. If health doesn’t matter, or you are using a respirator, then either will improve separation and lower suction.

I added the Wynn filter to my (Thien-tophat w/30gal) HF-DC and could not be happier.

FWIW, I spent ~$50 to build my own Thien top hat, and that sure beats ~$240 for the Oneida Super Dust Deputy. Either way, one must furnish the other parts for both systems; Collector can, DC system, Wynn filter, hoses&fixtures… just sayin’...

And +10 for “brtech” about buying a bigger DC if you are willing to extra hundred$ on the separator. IMO, it is rather oxymoronic to add a high-dollar separator to a low-dollar DC…

I am installing a Super Dust Deputy mounted on a 55 gal drum. My DC system is going to exit to the back of my shed where it won’t bother anybody. I don’t heat or cool my small shop as I am just a hobbyist.

I have a HF collector with a Super Dust Deputy sitting on a 55gal drum. I also bought a new filter from Grizzly with a turn handle to knock the dust down. I had a Wynn, but was a real pain to keep it clean. The system works fine, but when I use my drum sander, there is so much dust, that it does go into the filter. All I have to do is turn the handle a few times and watch all the dust fall into the plastic bag.
I will eventually buy a real cyclone, but for now what I have works good enough to not have to think about spending $800-$1,500 for a cyclone.
