An auxiliary dust collection system can be interposed between a sander or other dust producing tool and a vacuum source, e.g., shop vacuum. This auxiliary system has a cyclonic separator connected by a flexible hose to the tool and by another hose to the vacuum source. The cone of the separator is mounted onto the lid of a drum into which the dust precipitates. For a tool that has its own blower, the vacuum source can be omitted, and the air leaving the outlet duct of the separator can be filtered and returned to the ambient. A drop in silencer formed of a sleeve or tube of acoustic foam can be positioned into the inlet side of a filter cartridge following a cyclonic separator. The silencer absorbs a significant fraction of the process noise.
