Just finished pouring the slab for my new 40x60x16 polebarn. All that remains is the driveway and installing electrical and lighting. In floor heat, 320a service... all the goodies. Found a deal on an Atlas 3ph 7.5hp compressor and will be setting up the 3ph converter in the next month or so. I have a 3hp Grizzly dust collector that was in my last shop and want to set it all up as soon as the weather breaks. In the last shop, I ran all 4" PVC (I know). Would like to set this one up correctly using metal ducting overhead but am concerned about the length of the runs. The dust collector will go in a room designed for "noisy stuff" at the back of the shop (14x24 buildout section). The duct will have to be routed from the DC up to the ceiling (16'), then run the length of the shop (40') with drops for 2 table saws, the jointer, chop saw, planer, and etc. The workshop area of my shop will be 28x40 so lots of goodies to plan for.
I know there to be lots of knowledgeable folks on the forum so hoping someone has advise on sizing the runs to keep the system as efficient as possible. Would love a cyclone at some point but don't know if it's in the budget for a while. So far thinking 6" main with 4" drops for equipment (all solid pipe and minimal flex). Grizzly site says the DC is pulling approx. 2300 fpm.
Anyone have any suggestions or comments before I start this endeavor?
