Hello all. I’ve bought an Oneida 3 HP dust collector, have nearly assembled it, and now am about to design my system.
Anyway, I’ve decided on the S&D (sewer&drain)(schedule 2729), and will use 6” for all. My space is approx.
25X30’ feet in my basement shop. All suggestions welcome.

minimize angles -
try to avoid 90 (use 2 45s instead)
keep runs as short as possible
have one main run with drops as opposed to many individual runs that merge at the DC

do research on DC design and planing – oneida website has very valuable writeups on that..

Purplev said it all, The only thing I would add is come up from the floor which is not posable for most shops.

If you haven’t seen this yet, it’s a place to start.

And before you plumb everything with 6” duct work I would check with Oneida (if you haven’t already) and see if that’s a good idea or not. I was going to use 6” too when I installed my Oneida Cyclone and they told me to use 5” not 6”, even though the Cyclone’s inlet is 6”

Thanks guys,
I’ll follow the printed Oneida installation instructions and go with the 5”. After reading Bill Pentzs’ treatise on dust collection, I was convinced that the 6” was the way to go.

That is awesome! I’ve been looking for something like this which really helps with setting up the system properly.
I have a 2 HP Jet system, but this gives me good ideas on how to proceed.
