The Bosch VAC series dust extractors come with the best in class combination of air flow and suction power, making this unit ideal for dust extraction. The VAC090S is capable of wet and dry pick up. When paired with a HEPA filter (accessory VF120H - Not Included), this unit has been independently tested to meet the EPA definition of a HEPA Vacuum. The semi-automatic filter cleaning system provides the benefit of allowing the filters to be cleaned whenever it is needed. Use the convenient trigger on the nozzle to clean filters easily. Power tool activation reduces the need for a second extension cord, as the tool can be plugged directly into the dust extractor. Heavy duty wheels, a locking castor, and L-BOXX compatibility make this more than just a typical dust extraction unit. Click the L-BOXX onto the top of the dust extractor to create your mobile work station.
