Hello all, I am re-designing my dust collection system this year. I currently have a Grizzly 3HP dual canister machine with 7” inlet. This machine is hooked up to a router, two stationary sanders, a dual drum sander and a planer right now. I use 7 inch pipe all the way to the machine where most go directly to 4” to hook up to the machine. Except the dual drum and the planer branch off the main trunk with 6” and then to 4 at the machine. All have blast gates.

I now have a full size (48×96) CNC machine and I want to hook it up to this same unit. The problem is that my shop is pretty big, 50 Foot long, so I am worried about the loss of suction that may happen. The good news is that I use a second dust collector on the opposite side of the shop so this collector does not really branch off horizontally for more then a few feet until it drops to the machine. Is this collector strong enough to clean a CNC and still run almost 50 (60 if you count going from the inlet up to the ceiling) feet to the router? If so, how long should I stick to the main trunk being 7” before dropping it to 6”? If I do not have to upgrade the dust collection unit I will have plenty of $$ to buy all smooth wall metal ducting so that should not kill airflow at all. Thanks in advance for any advice!

Note: this is my dust collector:

Can you relocate the dust collector to the middle of the shop? It seems that would lower the length of the horizontal runs. Hard to guess without knowing the floorplan of the shop

Have your say...
