Default Piping the dust collection system to table saw

I’m tired of tripping over the flex pipe from the DC , so I was going to go with the 4” flex piping I have now from my General DC to a 4” vertical section of ABS secured to the wall ,
then I read you should use two 45 degree pieces to make the 90 degree turn less aggressive at the top where it turns .

My question is , it would look prettier if I went right to the 10’ ceiling height with pipe before I dropped back down at the end of the table saw ,but I’m wondering if having such a high piece of tubing would give me less performance?

I could use hangers and have the 4” ABS at 6.5 feet instead , as I could still walk underneath it , but I think that would look strange ?

The DC is going to be located to the side of the table saw , but against the wall .
I was at WP, and I found out the outside coupler on a 4” piece of ABS fits the flex hose he sold me before ,as I was concerned about size issues .
Not sure how I’m going to build the piping where it comes out of my saw , and hoping I can use a 4” ABS 90 . I’m also going to need a splitter on the table saw pipe so that I can get suction on an overhead arm I bought from SawStop for on top of the blade.

Update : My DC is 1.5hp -1250 cfm

I donít always insulate , but when I do .
Ok ,I never insulate

First suggestion, Rick, is to pick your feet up when you walk over the flex hose. I have two 4" hoses on the floor and step over them all the time.

What HP is your DC? Does it have the power to add the extra length and vertical rise piping?

I would think that if you have sufficient replacement air at the saw that you can maintain the velocity needed for the lift. The dust particles will rely on velocity of air to keep moving rather than suction/vacuum. Once they get to the lateral run and down run to the DC, they don't have a chance. Whatever you do, don't seal the saw too much...

I'll be doing the same thing in my garage...up 9 1/2', lateral for about 15 and then down to the DC. And I don't think I'm going for a raised floor......I'll be using 6" ducting...

What is the CFM for your DC...?

BTW...maybe this article might help... http://billpentz.com/woodworking/cyc...ccalc_faqs.php

Pick your feet up
I just find it a nuisance is all . Best case scenario would be a dust collection system build right under the tablesaw extension.

Looks to be a 1.5hp - 1250 cfm . Wish I paid a few dollars more for a little more snuff

If I was building a new garage I’d be putting 4” pipe under the floor. Don’t really feel like cutting my floor at this point

Not sure you're gonna get 1250CFM out of the 4"...at 1.5hp, maybe it's less...?

I checked the specs and it claims 1250. There’s a more expensive one that was about 300 cfm more , wish I bought it back in the day.

Reading your link I see you need a 6” duct for 1250 cfm. I suspect mines rated as if the two four inch ports were not installed , and you were just using the 6” port on the machine
