Three Vacuum Styles
Three vacuum styles mean one is right for your application.

• Popular and powerful non-vacuum sander comes with a 3M™ Hookit™ Pad included. Non-vacuum models are used in applications where dust extraction is not a concern.
• A central vacuum-ready sander, with a 3M™ Hookit™ Clean Sanding Pad, easily attaches to an existing central vacuum to evacuate dust.
• Our self-generating vacuum sander is designed to work with the 3M™ Clean Sanding System.™ It comes with a HEPA-rated Clean Sanding Filter Bag and Clean Sanding Hookit™ Pad.

Breathe Easy and Maximize Performance, Productivity
The 3M™ Clean Sanding System™ helps you control this fugitive dust and thus:

• Attain a better finish when the abrasive is kept clean
• Reduce cleanup costs
• Extend abrasive material life
• Reduce buffing and rework
• Maximize your profits
• Breathe cleaner air

Hookit Attachment System for Optimal Performance
3M™ Hookit™ back-up pads are perfectly mated for use with hook-and-loop style 3M™ Hookit™ sheets. They’re ideal for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. The 3M™ Hookit™ attachment system allows you to easily attach, detach and reattach the abrasive, thus utilizing the entire life of the sheet, resulting in less shop waste.
