Abstract: A dust collector for collecting sawdust and wood chips during use of wood working tools includes a conduit or hose connected through an impeller forcing air with entrained dust and chips to an inlet ring of a single stage dust collector. A particle collector reservoir is connected on the bottom of the inlet ring and a filter element is connected on top of the inlet ring. A tapered ring wall with a central opening is provided in the inlet ring and a baffle is mounted in the central opening of the ring wall. The baffle is of a cone shape and tapers an opposite direction from the frusto-conical ring wall. The inlet opening of the inlet ring is directed to between the ring wall and the baffle.
