Dust Collector recommendations

[Scott Winners]

Recently I put together a duct taped air cleaner with four 2" MERV 13 filters and a typical HD/Lowes fan. Did that really just as an experiment, but having that cycle on with a timer 3 times a day for 30 minutes has reduced the ambient air particle count to amazingly low levels. So the cheap/homemade air cleaner does work impressively well.

Since you have both an air quality meter and more than one air filter to use I would very much like to see some data in its own thread of what ordinary particle counts are for you.

Hi Alex,
Haven’t listed it. Where are you? I am in La Follette, TN near Knoxville.

Everyone's is different, but typically my ambient small particle count on my Dylos (so 0.5 microns) is about 500. If we have a Saharan dust cloud, I've seen 1000. Best is around 350. And I'm on the water on the Gulf of Mexico.

If I let the filter box go three times a day for 30 min, and I'm not in the shop, the ambient small particle count gets down to 100 or less when I walk into the workshop in the morning. If I run all three air filters for 2 hours, I can get small particle counts around 10, which is absurdly clean air.

Doing it over, I would get the 3 hp Oneida V3000. https://www.oneida-air.com/dust-coll...ollector-v2019 . I bought the Super Dust Gorilla 2 hp 10 years ago and have been very happy, just wish I had bumped up one size to get a bit more suction. 26 Ga snap lock steel duct works fine and is economical and self grounds and is available in one inch increments. 7" is the sweet spot for your mains with a 3 hp DC. Ever seen a pro shop with PVC duct? Just to be sure you get a DC with at least 8" WC suction at 800 cfm.

I read all the responses on this thread, there is a lot of good information and advice. But is interesting that no one mentioned the Oneida Supercell. It looks really interesting, it is a 5HP unit and according to the website it covers tool collection diameters from 1" to 5". That seems to cover the majority of handheld and stationary tools, like a 17" Grizzly Band saw, for example, have 4" OD collection ports. Another super interesting factor is that the Supercell seems to cover both, the high-volume-low-pressure and the High-pressure-low-volume Scenarios. I am really interested in everybody here's opinion on that equipment. Thanks in advance, Guys!

Supercell is a very nice product if you have a shop size and tool assortment that it is optimal for.

On a related DC note, I'm about to set up the piping for my DC. Going to use 4" sewer pipe. The photo is from a Jay Bates article. He has an adapter inside a Y that he attaches his overarm Sawstop hose to. I thought it was a nice setup, and would work well for me, but I called Rockler and they don't know what I'm talking about. I sent a question to Jay Bates too, but he never got back to me. Anyone here have any ideas? The OD of the SS hose is 1 3/4", but it's rubber so there's a fudge factor there. TIA. Mark

Hi Mark
if you are talking about the black adapter in the Y, that is a reducer. Rockler has them on their web site so I don't know why they could not help you on the phone. I think you could get a rubber Fernco one from big box stores. Hope this helps.

Luis I looked at the Supercell until I saw the CFM rating of 465 CFM. Then I realized what it is.

It is an interesting and unique product. I classify it as a shop vac on steroids. After a few measurements of my unit before I make changes, this CFM is in the high range of what I'm getting but most likely this is at nearly zero pressure drop.

But it is still a good spec because one would have to assume it's curve is a bit better for holding that value for some of the pressure drops we typically impose on these units than a typical dust collector design. This is based on the specification given of 98" water column at zero cfm.

But if they really wanted to impress all of us they would show the fan curve.

The Supercell isn't really 5 hp continuous but like a shop vac it can produce 5 hp briefly. Most (if not all) of us need continuous power for our dust collection system.
While I can see it working for some of the high pressure drop pipe/hose setups we often configure for our dust collection, there are better overall solutions at a lower cost.

The other nice thing about typical high flow dust collectors actually is they don't produce the high vacuum pressure. When I run my unit completely closed I don't have to worry about collapsing pipes, collection canisters, and other components. This can actually be an issue rather than an advantage. In the end - I want high flow and not high vacuum pressure.

At least that was my conclusion after looking at it.

It certainly does help, Luis! Thank you for the reply! Mark

My overarm collection is also 2.5 inch split off a 6 inch duct . I'd say it is fair-to-good . The big improvement came when the over the blade shroud itself was replaced with a wider version .
