An old Kity bag dust collector was brought back to life. Duct tape was necessary, but the fit is stable and appearance is OK. Surprisingly, the amount of floating dust in the 20x20 shop drops dramatically if the unit is simply run for 5 minutes. Airborn particulates seen in shafts of light coming through the windows just melt away. Sturdy construction, good fittings and quick shipment make this canister and Grizzly winners for me.
