I'm planning my DC setup for a new home shop. I've mostly made up my mind on the 1029Z and PVC drain pipe for the duct work. I think I want to run a 6" main line with 4" branches so that I can use both 4" ports on the BS and (future) downdraft table at full capacity.
I also want to use a garbage can cyclone separator before the DC for collecting planer and jointer shavings and I don't see any garbage can separators with 6" inlets/outlets.
I could:
- Just run a single 4" duct and loose quite a bit of capacity.
- Shrink down to 4" immediately before the garbage can and expand back to 6" immediately after it, but I'm a bit concerned that will either restrict air flow too much or increase the air velocity enough so that the separator won't separate much.
- Buy a second cyclone separator, run both 4" intakes from the DC into separators, and then recombine into 6" duct.
- Run two separate 4" lines, one that is only used only for dust and one with a separator that that is used for dust or chips.
- Remove the Y fitting off the DC. Skip the separator and empty the bag more frequently than I'd like.
- Remove the Y fitting off the DC and run 6" pipe to a home made 6" cyclone lid before the main line.
- Have someone on the group tell me where to get a 6" separator lid.
Any suggestions?
In case it matters, I will have no more than 3 branches/90 degree turns and 30' of pipe between the DC and the furthest tool. I'll use blast gates and will very rarely be using more than one tool (at most two 4" ports) at a time.
Is 6" duct overkill for a 1029Z and a small shop?
