Whether it’s called a pre-sorter, 2nd stage, cyclone separator, or chip collector, they all do the same thing; filter out larger pieces of debris before going into your dust collector’s bag and extending the life of the filter. In this episode, I install one on a Delta 50-760. The early steps could be applied to any dust collector with only final fit specific to the Delta. Combine this with a pleated filter for a complete dust collector upgrade.
The Rockler fittings were not used in my install but is listed as an alternative from a more recognizable brand. Cheers.
