I am planning on purchasing a cyclone dust collector for my small shop and looking at the Grizzly G0440. I also plan on venting the collector outside. It seems a waste to have to purchase a new unit which includes a filter and then not using the filter. Does anyone sell a cyclone collector without having to purchase the filter and assy.? The Clearvue unit is just overpowered for my needs. I called Grizzly tech support and they said they only sell the complete unit, seems like they are missing a market as I am not the only one who wants to vent outdoors. What have those that do vent outside have done in this situation?
