Topic tags/keywords: dust collection shop ducting question

Have already purchased Oneida DC, and a contractor gave me his price for installing ducts.

My shop is built in the loft of our barn, the DC will be mounted on the lower level, main duct running under the joists down the length of one side, with smaller take offs running between the joists, and coming up through the floor at the tool locations.

Main duct 35’ x 7”
Two runs from the main: 30’ x 6”, then 4” through the floor (typical), picking up two machines each
Three runs: 4’
One run 22’

Any idea what the cost of the fittings, ducting, and labor would or should cost? The guy quoted me $1600.00, is that reasonable? If it could be made out of wood, I would do it myself…

Will post photos tonight of my shop, so that may give a better idea of layout.

Thanks for the help.

I was just quoted $400 for duct only (materials) for (all 6”) 50’ pipe (10×5’), 6 6×6x6 wyes, 3 bends, and 7 6×4 reducers. so your total of 1600 including labor doesn’t sound over the top to me considering your duct uses some 7” and longer runs in total.

FYI. I went with 4” PVC for lack of funds. 50’ duct + 6 wyes, and 5 45s for under $100. have you tried looking at 6” S&W pipes?

Given the size and length of your runs, $1600 sounds very reasonable. When I did this, the cost of the spiral piping, fittings and gates rapidly approached and nearly exceeded the cost of the cyclone and that was for a 6” main.

Wow, I had forgotten all about this. It was over two months ago when I posted the question…

Thanks for your replies.

It did not quite turn out the way I had stated it above, but almost all machines are connected (procrastinating about the drill presses) and it works great!

Cost was very close to the $1600.00, but I bought blast gates and my flex hose to connect the machines at Lee Valley, so that added about $450.00.

It is kind of embarrasing, but we shifted focus to more horse related activities just after I bought the Oneida system in 2005, and after we hung the cyclone it nothing more was done for 5 years, until ducting was completed this summer.

My warranty was over before we even wired it up… but I am very pleased with how quiet it is.
