Model 650 dust collectors hook up to 1 to 3 machines at a time for optimum dust cleaning. Each 650 series dust collector comes equipped with a quick-install collection bag, single-stage design for economical and quiet operation, 4 casters for maneuverability and total portability, and permanently lubricated, fully enclosed, fan-cooled motors for continuous duty. An optional remote control is radio frequency so there is no need for line of sight to turn the machine on and off.
