Would a small shop DC system run ok with the mains at 4" smooth bore PVC
ducting vs 6"? I would have about 30' of main and 4 drops using a 2hp
1600cfm unit and air blocks for the station no used. The DC has a 5"
intake and 12" impeller.
I cannot find locally PVC 6" sewer and drain pipe. I can find galvanized
6" duct at about $1.40/ft and 4" smooth bore S&D PVC pipe at $0.58/ft. I
hate to spend more of the duct then the DC which would happen if I go the
metal pipe route.
I visited all local Home supply brands (HD, Lowes, CW) and all dont carry
over 4" pVC. And I called an irrigation supply and they dont carry the
light duty 6" PVC pipe (i think its schedule 2379 or something like
that). Im guessing that its not a big seller inmy area for some reason to
do with building codes for such things.
So any way, I was wondering how much performance I lose by going the 4"
vs 6" route.
Any thoughts appreciated!
I would go with 5" or 6".
Do you have a plumber friend that can get plastic from a wholesaler?
Also, where are you at? Your location may pop someone out of the wood work
with a local supplier.
