CFM = cubic feet per minute – it is the volume of air moved

Look up the Thein baffle or seperator to use with your shop vac. You can build on of these very easily and it fits on top of a trashcan. It will seperate most of the dust and woodchips from finding their way into your shop vac filter. The dust deputy is also great for use with the shop vac.

I have one of the small red dust collectors from Harbor Freight. It was about $100. It works well enough for my small shop and is a more tollerable sound than the screaming Ridgid shop vac. If it is hooked to one tool at a time it would probably be sufficient, but in no way compares to the larger 2 bag units – even if the CFM listed is close. The bigger unit is just must more efficient at moving dust.
