I got the cyclone installed yesterday and am most impressed with it. I have owned the 2hp Harbor Freight and then upgraded to a 2HP Shop Fox (1550 CFM) so as with every machine I've ever owned I seem to buy 3 before I get to the one that really works. Some form of dust collection is better than no dust collection at all, with my previous bag collectors I used a Delta Air Filtration unit and it did a good job of picking up all the fines.
This is a 3HP (Leeson Motor), 1100 CFM @3.3 SP, I ordered the 55 inch drum which makes the unit 96.6" tall. The packing was done extremely well with non expanding foam and arrived in great shape. It took me 2 hours to get everything installed and I was able to do it by myself, but it would have been easier with 2 people for sure.
I'd have to say that this unit is quieter than the Shop Fox by far and the airflow is much greater to my machines. I figured I have almost 4" of static pressure loss to my table saw, which should put me close to 1000 CFM at that machine. When I turned the machine on for the first time the flex hose jumped off of the floor to the table saw and I was amazed at how well the airflow was compared to the dust collectors I've had in the past. The Hepa filtration is also a huge plus, not that I can see a micron, but with all the dust I sent through it, I couldn't see or smell a leak.
Oneida was the only company that answered the phone and could answer all of my questions when I called. I called/emailed Grizzly and Penn State as well. The Rep. at Oneida didn't try to upsell me on the Gorilla line and said the V system was more than enough, and it is indeed. The unit wasn't cheap at $1782 shipped, which included the larger drum, shipping and Oneida threw in a free remote. The Grizzly was $1414 shipped, but wasn't made in the U.S.A. either, so the customer service, made in the U.S.A. and a quality made product. Wood magazine did a great comparison of Cyclones and Oneida did the best with filtration and that had bearing on my purchase as well.
