I'm in the process (slow) of installing a CL find: 3hp Oneida cyclone - about 15 years old, 7" round inlet, 7" square outlet.
I've been planning out the duct runs in a 20 x 30 shop, branches and drops to 6" jointer, lunchbox planer (w/ 4" branches to DP and CMS) 10" cabinet saw w/ integral router table, and 17" band saw. Unfortunately, the TS and BS are at the end of the run.
Per recommendations, I've got 2' of 7" pipe running straight into the cyclone. It will then elbow up to ceiling height (10'), elbow and run straight for a bit, and elbow again to run down the center of the shop. Again, per recommendations, I will reduce to 6" on the main run within 5 - 10 feet.
I've been planning based on 6" branches and drops, but I'm having second thoughts about reducing further to 5". Any thoughts, one way or the other?
I've been to Pentz's site. I'm not planning on modifying the machines to allow 6" all the way - I'll be using 4" flex to connect to the machines, keeping it as short as is practical.
Additionally: the CL deal included a goodly number of fittings (yay!) and 6" pipe (one reason I've had 6" on the brain). The square to round adapter for the outlet goes to 6" round - would it be better to have a 7" outlet? BTW, this will be direct to the outside - no filters.
And the opening at the bottom of the cyclone (9") has a shop made adapter reducing it to 6" into the bin. It seems to me to be wise to make my own, increasing this to 8". Thoughts here?
Thanks in advance.
