Featuring a best-in-class combination of air flow and suction power, this Bosch 9-Gallon Dust Extractor (VAC090S) is capable of wet and dry pick up. When you pair it with a HEPA filter (VF120H, sold separately) this unit meets the EPA definition of a HEPA Vacuum. The semi-automatic filter cleaning system allows the filters to be cleaned whenever it's needed. Plugging your power tool directly into this Dust Extractor enables you to activate it each time you pull the trigger. If you happen to have an L-BOXX, you can click it right onto the top of the Dust Extractor to create your own mobile work station.
