Hi,
I’m in the process of purchasing a new dust collection system and have generally decided to go with Oneida, either the 2.5 portable of the V-2000. But I recently came across the JDS 2 HP cyclone and was very impressed with the design and the specs, though it does seem that a 2 HP motor rated at 1700 CFM, with a 8″ diameter inlet and 74db noise rating seems almost too good to be true. So I’m wondering if anyone here who has experience with this machine and/or the Oneida machines would offer some comments regarding their performance, etc.
Any information would be very much appreciated.
Thanks

I can recomend this setup by Grizzly. I'm sure the one you're looking at will work fine. Compare the specs. The Griz is less than half the $ and really sucks!. Get the remote switch.

DC Performance
Congratulations on looking at 2 stage collection. There are some simple charts on Bill Pentz's website which help in determining whether or not a fan can deliver the promised CFM and SP.

The DC industry is quite tight lipped on how the theoretical maximum performance is measured.
I think you would have to search out comparative reviews from other publications.
I have a Clear Vue CV1800, with a 5HP motor driving a 15" impeller @ 3450RPM rated at 1442 CFM.
The CV1800 MAX is the same except it uses a 16" impeller and 8" inlet and is rated @ 1935 CFM.
1700 CFM with 2HP, seems to be a very high theoretical performance.

I bought an Oneida 2HP Super Gorilla a few years back and have never been disappointed. I concur w/ others that ratings can be misleading. So, I called Oneida and explained what tools I had and they made the recommendation. It cost a bit more than some of the others, but has never let me down. I use it w/ a Delta 15" planer all the time and it leaves no dust behind.
1700CFM?
Chances are this is the CFM with no filter, and no pipe... It really is a pointless number.
What you need to look at is the CFM with the filter installed and the amount of ducting you are planning on. The filter and the duct add resistance to the system... Most manufacturers have a fan chart, that will show the CFM at a given resistance. I think you'll find that once you add teh filter and a bunch of tubing you'll be around 800CFM (depending pipe type).
At 800CFM 8" diameter pipe is too big to move chips at a fast enough speed... so you'll need drop down to a smaller pipe anyway.
I've been using a 2HP Onieda in a small shop (read limited amount of DC pipe) and I've been really happy with it.
I'm not a fan of the Doom and Gloom on Mr. Pentz site... but if you can wade through that you'll find a lot of really good information.

I installed a 3 HP cyclone by Grizzly last winter and i'm pleased with it so far. The cost well a lot less than the oneida.
