3M SGV sanders are an integral part of the 3M clean sanding system made up of the SGV tool, clean sanding disc pad and clean sanding disc, sold separately. Together these components are engineered to effectively eliminate dust from the workpiece and surrounding space. The SGV sander uses the inlet air to create its own venturi vacuum that extracts the dust from the work surface and expels it through a wide collection port on the back of the tool into a filter bag. - 3M Self-generated vacuum random orbital sanders (SGV) are air-powered and deliver professional performance and a swirl-free finish in high-production industrial environments where dust extraction is preferred. The 3M Clean Sanding Filter Bag included with the tool achieves superior HEPA-rated dust collection with an air filter inside the bag that locks dust away and effectively retains it for disposal.
