The WOLF VAC 3S w/ Separator is equipped with a manual lever that will clean the filter with a jet pulse. It includes floor cleaning tools and comes standard with a HEPA filter. There are no circuit boards, which provide simple operation settings and a collapsible frame for easy transport. When your dust extractor is prematurely clogging due to large quantities of material you are covered with the Separator. It captures 90% of the material BEFORE it reaches the dust extractor, keeping your dust extractor filters clean.
