Hey all!

I’ve got a HF dust collector with a Thien separator (all 5” fittings) and a Wynn .5 micron filter. From there, I’m going about 15’ across the ceiling with 5” metal snap-together duct. What I’m trying to figure out is, what’s the best way to get it to my table saw?

I was going to come down the pole with more 5” metal to a blast gate and then adapt to 4” flex for the 10’ into my table saw. I was originally going to go 5” all the way to the saw, but it seems everyone is using 4” – plus, I’d eventually like to get a 2-1/2” hose above the blade and with 4” below, I’d still have enough draw above.

Will the 5” metal fit on to a 5” blast gate? How would you adapt to 4”?

Here’s a pic to show you what I mean:

Any suggestions would greatly appreciated.

Thanks!

I would put a 5” to 4” reducer right on the back of the 5” blast gate and run the rest in 4” pipe to within a couple feet of the floor, then use 4” hose to the saw. You could at some point in the future add a wye for the 2.5” hose for the overarm dust collection. If you’re worried about the draw for the overarm, you could add a 4” blast gate before the hose to throttle the cabinet collection to get what you need to catch all the dust from above.

stay with the 5” as long as possible because there is a lot less friction in 5” than 4” which will improve the air flow.
