Empty onboard dust boxes without a mess. The Dewalt Dust Box Evacuator, DWH079D0XJ, is the world’s first easy solution to safely dispose of concrete dust collected with any of our OSHA Table-1 compliant onboard dust collection systems. Remove the dust box from your tool, slide it onto the dust box evacuator, and turn on the vacuum to clean the dust box in seconds. The evacuator is airlock ready, making it an easy attachment to add to any dust extractor fitted with a DeWalt AirLock connector.
