I hadn't thought of hooking two shop vacs in series, but I guess that could work. I was talking about two stage impeller designs. The vac unit we used in 2008 was a two stage impeller, it had two impellers on one shaft, separated by a flow straightener. Some vacs have wide single impellers for max flow, some have two narrow impellers for max delta P.
