I’m picking up my first dust collector. Do to my shop orientation, it is going to be in a corner of my garage.

I’ve read that using the largest diameter duct you can will be best, but due to my configuration I can either run one 6” at a 45 degree across my garage (from one corner toward the opposite one; or I can run two lines more directly and cap whichever not in use. Would I benefit from shorter runs with 4”?

The DC is 1100 CFM 1.5 HP if that helps.

Thanks for advice!

What diameter impeller does your DC have?
I’ve found that fans 14” or so (and bigger) perform better than the HP rating would indicate.

I have a 20 year old 1.5hp Delta that I use. It’s at the far end of the shop. It’s about a 40’ run to the table saw, jointer and planer. I’m using 4” spiral pipe with one 90 degree corner (wide sweep). I only use one tool at a time so it’s worked fine for me.
I just upgraded to the cool iVac automated setup with auto blast gates, it’s silly for my situation, but very cool and handy.
Btw, I have a few extra 90s, wye’s, connectors and blast gates available.

My DC is in the corner as well. It is an old north state 2 HP that I converted to the jet pleated filter and vortex cone. It was never rated for CFM 25 years ago. I ran 26 guage steel duct, 5”, with long radius 90’s. I built my own y fittings with a spot welder. I split right after the input, and wrapped one wall about 3’ high. For the other wall, I went up over the ceiling, then along the other two walls. 4” drops off the 5” main and a blast gate at each machine. This saved running everything up to the ceiling. It works great, and the longest run up over the ceiling is over 50’. I run one tool at a time.

I think that 6” ducting is too large for that dust collector . It will pull nowhere close to 1100 cfm.

Yes, I agree. 6” is too large. You need to use 5”. Makes a huge difference. 6” is about 50 percent larger than 5”.

I ran my dust collector metal duct along the wall on the floor, then up 2-3 feet to each machine. This saves a lot of duct going up to the ceiling and back down to the machines. I arranged my shop to accommodate this set up. Works well for me.
