Oneida Dust Deputy

[bobgroh]

Oneida Air Systems has a little cyclone and collection barrel that acts as a pre-filter for a 'shop-vac' type dust collection system. Does anyone have one or have an opinion that they would like to express on it?

Hi,

Can you direct us to pictures?

I think this name sounds familiar like didn't I see them using some sort of vortexy thing on a floor sander(maybe this old house)?

I have plastic top for a 20 gallon trash can that I use but this might be a very different system...

You are absolutely correct. There was the 'vortexy' floor sander on TOH. And the Dust Deputy is a vortex collector mounted on a drum. Take a look here:

Assuming that comes out ok. If not, I'll try another way to list the URL:
The Dust Deputy (http://www.dustdeputy.com/)

And we'll see what happens! Neat little device. Uses air flow from ShopVac (or equivalent).

That looks like something I'd like to have... I will pencil it in next years budget. Think they will be on sale next year????

Looks like they have been around for a while but I had seen one except for the one Norm showed us.

Many many years ago a company was promoting a vortex cooler so we got one to play with at work for cooling electronic circuits, they used compressed air to create a pressure drop... and well it did work but wasn't practical for what we needed... now I wish I had the parts from that and could made one of these.

If you do decide to get one keep us posted, a review would be nice as well.

Both Rockler and Woodcraft have similar accessories on their websites. They are a bit more money, but I'd save on the shipping costs. Are there any differences between these and the "Dust Deputy"? <Strike this paragraph.

I stand corrected. When I first hit the link in Bob's post I apparently was misdirected to a different website that listed the "trash can topper" type of dust collector. These will not work as well as the vortex type such as the Dust Deputy. However, they actually cost a bit less, ringing up at about $20 for the 2.5" hose, 5 gallon bucket model, and about $27 for the 4" hose, 30 gallon trash can model. Here they are on the Woodcraft (http://www.woodcraft.com/family.aspx?familyid=4310&productid=143290&mode=details#tabs)site.
Since I'm using a Delta dust collector I have 4 inch hoses. Anyone know of a true vortex-type separator with 4 inch inlet/outlet? Or have plans for building one?

Hi,

Any chance you could post a link?

looking around the Oneida site, I see that the 2" Dust Deputy package currently has free shipping to CONUS.

http://store.oneida-air.com/dustdeputypackage-complete-1.aspx

the package comes with 1 adapter for using 2.25" hoses. that seems odd to me since both the inlet and outlet are 2" and you need hoses on both sides.

FWIW, unlike most of the bucket top separators at places like woodcraft (Woodcraft Trash Can Cyclone Lid), this one at least looks like a vortex separator. having the air come in tangential to the upper rim of the cone, the air going out the top center, and the tapered sides for the solids to slide down to the dump are all necessary parts for a vortex separator. the other types are mostly just settling bowls and, as noted in other threads here, are prone to significant head loss.

back in my CFD days, it took a bunch of computer time to optimize the cone shape and size for these things but I still have problems understanding why the prices they are asking for these things are so high. seems like, other than raw materials cost, they ought to cost about the same as each of the separators in a home vacuum.

when an entire Shop-Vac with hose and nozzles is less than $80 at Lowes, $200 for one nozzle seems pricey. having to buy the second in/outlet adapter set to hook up the other hose just seems greedy.

of course, I still find myself looking at the Woodcraft #149162 version and hoping for a good sale. :o
