Your shop-vac may not be the most efficient dust collector, but you can turn it into a two-stage dust-collection system with the Mini Cyclone Separator from Woodstock International. You’ll change the bag or clean the filter less often, because larger chips will drop out into the attached five-gallon bucket.
Woodstock molds their Mini Cyclone Separator from ABS. It sits on top of a standard five-gallon bucket, where it accepts two 2-1/2″ hoses. To empty the bucket, simply lift off the separator.
Look to pay anywhere from $17 to $24 for the Mini Cyclone Separator. You’ll have to supply your own five-gallon pail. If you have 2-1/4″ hoses, you can get a reducer for about $5.
