I started out with a shop vac. When I added the 5 gal dust deputy kit, the convenience of not having to clean the filter was awesome, but if anything I noticed a slight decrease in suction. Bound to happen, the cyclone will kill the CFMs a bit.

This worked ok, but cant even compare to a real dust collector. I got a Craftex CX 404, 1hp, rated at 820 CFMs with a 1 micron cloth bag. The old shop vac had something like 75 CFMs. Now I do understand that manufacturers boost ratings, and since IM using 4 inch lines Im maxing out at around 400 CFMs anyway but the dust collector feels like 10 times the suction of the shop vac on its best day.

When I add a THein top hat, Ill lose some CFMs, but I hope to make up for it by upgrding the filter to a canister and improving airflow.

Sorry for the long rant. The dust deputy is great, but my 2 cents is save for a real dust collector.
