Topic tags/keywords: resource dc dust collection dual shop vacs

I’m getting ready to make a dust collection system for my shop vac, which will run to all of my tools using PVC, Y’s flex tube with gates to each of my tools.

I know it will not be as effective as a large commercial DC, so I would like to avoid a debate between shop vacs and large DC’s.

I had this unusual idea pop in my head that to improve it’s effectiveness, I could use two shop vacs. The PVC would connect to the Dust Deputy, which would have a short section of hose running off of it, than I could put a Y and have both shop vacs running simultaneously!

Would this improve the performance of the system? Or would the shop vacs be competing with one another? Not sure if the Dust Deputy is rated for this either!

Anyone tried it?

You forgot to mention size of your shop vacs, if they are small, then 2 might work together, but a Y would
make it difficult for them to compete against each other. Read Stumpy nubs blog on hooking 2 HF dust
collectors together if you want to get complicated. Read up on the Dust Deputy site to see what they
recommend for size.

I only have one 6.5 horsepower shop vac. I do not want them to “compete” with one another, but I would like them to work in tandem!
