I recently took delivery of my K3 and will at some point in the next 6 months hopefully receive my A3-31. At the moment I have a Grizzly 1hp Light Duty dust collector that I roll around and plug in machine to machine with 10' flex hose. I'd gotten by with it on my past table saw, but it is severely underpowered for the K3 and the incoming A3-31 so I need to step up my dust collection. My shop is pretty small and is actually my parents garage, so footprint and mobility are really important for me as I will always be rolling it around or getting a longer flex hose to accommodate. Comparing models I'm a bit lost with interpreting the cfm stats and would appreciate some real world advice as far as what would work based on my setup. I've been looking at the SHOP FOX W1685 which is 1.5HP 1,280 CFM, the Super Max 1.5HP 1,200 CFM, Jet 1100VC 1.5HP 1,100 CFM and the Mini Gorilla which is 1.5HP and 587 "Actual" CFM. The prices have a pretty wide range with the Grizzly and Super Max coming in less than $500 while the Mini Gorilla is around $1,400. I realize the Mini Gorilla is a different type of DC from the others mentioned so it's not exactly a fair comparison based on price but I've read great feedback on it so I wanted to take it into consideration. I don't anticipate my shop getting any bigger so I'm not in a situation where I need to buy for the future so to speak. I'd love to hear what you folks with similar sized setups are running and having work for you.
