The Cyclone Separator with a handle works by drawing the air downward as opposed to horizontally, causing the large debris to settle at the bottom of the can. The separator also has port holes that protrude out to provide an easy hookup for your dust collection hose. The handle on the cyclone lid makes cleaning out the can a snap, simply turn off your dust collector and lift the lid straight up and off of the can for easy removal of the dust and debris.
