Take dust-management to the next level with self-generated vacuum tools. Convenient Expanded Capacity 3M™ Clean Sanding Filter Bags come in two sizes: the Large bag has a 0.5 lb capacity, and the Extra Large bag can hold up to 3 lbs. Super-efficient dust collection and bag capacity save operators time because the bags can be changed out less frequently. Hose-Free Portability For use on a ladder, off-site, or in other situations where portability is essential, pair the Clean Sanding Filter Bag with a 3M™ Clean Sanding Filter Bag Backpack (sold separately), which protects the Filter Bag and enhances mobility. The Clean Sanding Advantage 3M Clean Sanding discs extract up to 96% of the dust generated during the finishing process, compared to 55% for most traditional 5-6 hole discs. Less dust leads to a better finish and cleaner working environment. Combine that with higher productivity and the longer life of non-loading discs and it's easy to see why our Clean Sanding system is the ultimate choice for dust-free sanding.
