My DC has a 5" dia inlet opening to the impeller.
If I go with 6" main pipe for my small shop DC system, should I open up the
inlet on the DC to 6".? Or should I make the mains 5" dia?
thanks for any tips
6" pipe will flow more air, but that 5" restriction will still be the
main limit to your flow. You may end up with probelms of dust settling
in the slower moving air in the 6" pipe rather than carrying thru the
5" into the collector.
If it were me, I would go with 5 " pipe.
Big chips will also loft the dust if they travel the same path.
I've got 6" 26 ga. HVAC pipe all the way to each machine and directly
into my DC1200, using Lee Valley 6" gates. It's exponentially better
than my old 4" plumbing.
On my Jet DC, removing the 2x4" plug uncovered a 6" outlet. I don't
think a 6->5 right at the machine would be a deal killer.
I bet you would be fine either way. 5" inlet or 6" inlet. To me it
seems like a 6" to 5" reducer would be a lot less work. I would do
the 6" pipe so some day when you are rich you can install that 10hp
cyclone collector and not have to replace the pipe.
Did you run a bare grounded wire through the inside of this PVC pipe? Since
you are not using metal ducking, you run the risk of burning down your shop!
Smaller dust particulates and a static discharge make for a very unhappy
