Hi All,

I’m new to this forum and this is my first post. I hope to one day be a consistent contributer here.

I just bought an Oneida 3HP Super Dust Gorilla. Bought it used for a good deal.
I plan to run 26guage galv. snap lock pipe.
Since the DC has an 8” inlet, my plan is to run 8” main line with 6” drops, and will probably have 4” to 5” flex hoses to the machines. At each drop, I will be using a 8×8x6” wye, with a 45degree 6” fitting, then 2’ of 6” pipe, and then a blast gate, reducer, flexpipe to the machine.

I am going to have a straight run for about 10’, (with 2 drops), then a 90degree turn and that will run for about 15’, (with 4 drops in there)
I will have blast gates at each drop, and will most likely only run 1 machine at a time, maybe 2 at the most.
Do these plans sound ok?
My main concern is if 25’ of 8’ pipe is too large and I won’t have the volume to carry the dust all the way to the collector.
I will be running the usual woodworking tools.
Thank you in advance.
Old

I would run all 6” and reduce to 4” after the gates. 3hp should give you plenty of suction for your needs.

I have 3hp grizzly with an 8” intake. I reduced mine to 6” at the cyclone.

It has performed great. I can easily have two 6” gates open at any time and it works just fine.

Here is my installation link#

Give close attention where I used a 6” to 2 4” for a single machine.

All of these cyclones are very good and you will be really happy with the results.

thanks for the info guys. And thank you for the pics Bartee.
I’m really glad I asked, b/c I was thinking 6” mains would be too small and would reduce CFM.

Thanks again for the info. And thank you to all that sent in the warm welcome!

Actually, do you guys think it will hurt if I just run 8” pipe as the main anyway? and branch it with 6” drops.
I would think so, since the inlet on the cylcone is 8”, but what do I know :)

Reason I’m asking is b/c I found 8×8x6” metal wye’s, for much cheaper than 6×6x6” metal wye.
and 8” pipe is not much more expensive than 6” pipe, it will actually cost me less to go with the 8” main…unless that is too big for this system.

Old,
Pipe type and sizing is critical to maintaining the proper movement of dust and the heavier particulate matter. I am using a 7” system on my 7.5 HP Torit/Donaldson system.
I would suggest your spending time reading Bill Pentz’s work on woodworking dust system to gain insight.

I believe you can contact Oneida and they will design a system for you. I dont know the cost if you didnt buy the system directly from them. It might be worth a call!!

Thanks Rust.
If you’re using 7” on a 7.5 HP DC, I guess I’ll go with 6”. I did read the Bill Pentz site, and that is some quality reading! But a serious brain overload…for me atleast.

And Ken, they charge $200 to design your system…a bit too rich for my blood at the moment.

But ok, thanks again guys, I’ll go with the 6” system.

Alright guys, I’m going to go with 8” for the first 2 feet, then reduce to 6” for the rest of the run. I guess if the 5HP clearvue is recommended to use 6” main, then this 3HP Gorilla will work fine with that.
thank you again for your input.

btw, I found that Ace Hardware Outlet (www.acehardwareoutlet.com) sells the cheapest snaplock pipe in 24 and 26 guage, but you need purchase in packages of 10 for their pipe.
and Silver Sheet Supply (www.silversheet.net) sells the cheapest fittings, such as Wyes, reducers, elbows, etc. I’m talking $7.60 for 6×6x6” wye. Most other places I see are like $20Plus each.

Once I recieve my order and put it all together, I’ll post a seperate thing with pricing, etc.

thanks again.

ps, A1jim, I checked their site and did not see anything on which pipe to run with their DC’s.

How do you like your 3hp Super Gorilla now that you have had it for a while?

Woodwrestler, the OP hasn’t posted anything on this site in over 3 years. Perhaps someone else will chime in.

Old – I have a 2.5HP Super Dust Gorilla with 7” inlets. I ran a 7” run directly out of the cyclone unit to the first “Y” (about 6 feet) then ran 6” lines from there. As stated above, check with Onedia but I believe that an 8” main line would be fine at least up to the first “Y” or Tee. I would consider dropping it down to 7” or even 6” after that.
