The Dust Extractor Vacuum (DWV012) was designed specifically to provide dust control solutions for drywall sanding and concrete grinding, cutting and drilling applications. The Dust Extractor Vacuum meets the EPA Lead Related Renovations, Repair and Painting (RRP) Rule for HEPA vacuums when used with DWV9320 HEPA filters (included with the vacuum). The DWV012 has continuous auto filter cleaning, which means that every 30 seconds one of the filters is backflushed with air to remove dust to provide suction until the tank is full. The HEPA filters should be replaced every 6 months under normal applications. The DWV012 includes a tool activation setting that turns on the Dust Extractor Vacuum whenever the user starts the connected tool, a variable speed to set the amount of suction and a bail handle for gripping and tying the tool down (ideal for users working on scaffolding or for transporting the unit). The large-mounted castors and large rear wheels provide durability and mobility when transporting and rolling the tool. Included with the vacuum is the DWV9000 universal connector.
