I agree with Brett¡¯s suggestion on this. ?You¡¯re better off sticking with imperial-sized rigid pipe to
and including the blast gates, and necking down to metric at each machine where flex hose is involved. ?I have an RL-160 with a single 6¡± Nordfab pipe running though the shop, branching off to imperial-sized pipes and blast gates as you can see in the attached. ?Those branches in turn have blast gates, then a fitting to convert to metric for the flex-hose connections to the machine. ?
You didn¡¯t identify the extractor you are using, but if it¡¯s a Felder RL-series on 3-phase, the extractor impeller is running 20 percent faster than the design target due to the difference in 50 versus 60 hertz. ?Have you factored that into your thinking?

Correction - "static head will be even greater at 7" or 8"" should read "static head reductions will be even greater at 7" or 8"" .?

To add to conversation, might make more financial sense in USA to buy 7" (not common in my experience) or 8" than to spec a special metric order. The static head will be even greater at 7" or 8", however line velocity for carrying the load should not be ignored. My main system has 8" mains, 6" branches, and reduces at the tools to metric or otherwise FWIW, BUT, I have to have 2 branches open minimum at all times to keep enough velocity to flush.
Hey Michael,
?
I just installed a DC system and sourced all of my quick connect ducting from the Blast Gate Co. () in Michigan.? They are incredibly well priced vs. others and were able to make custom reducers from imperial to metric and also carried metric hose to make connections to my machines (AD741, FB510, K700S, F700Z, HS950) easy.?
?
Regarding your inlet being 160mm, Blast Gate can make a custom fitting/machine adaptor for this and then make recommendations on using their imperial QC ducting with metric reducers as I mentioned.?
?
I would suggest you tell them how high ;) you are along with the specs of your DC and machines and they can draw up plans (at no cost btw).
