I built exactly the same vaccuum system with the DD and the HEPA and the dry wall bag. I put the whole mess on a rolling cart that I can wheel around from machine to machine. Works great.

I do think the DD is nescessary as not only will it extend the life of the filters but supposedly it will extend the life of the Shop Vac motor.

I would not use this for collecting overspray. I think it could be a fire or explosion hazard if used for that do to flammable thinners , etc in the paint..
