The company offers a kit that enables users to build their own dust separator for pre-filtering dust and debris headed for the dust collector. The pair of threaded elbow and coupler components form the essential infeed and outfeed ports of a baffle or cyclone system. According to the maker, the components are easily integrated—simply cut the holes in a container and thread them together. The reported result is less dreaded time emptying the dust bags, less time clearing clogs, and no heavy chips smashing into the dust collector’s impeller. (763) 478-8201, Rockler.com.
