Fein dust-Free sanding systems integrate a variety of sanders and vacuums into complete systems that can capture up to 98% of the dust created by sanding. Dust-Free sanding is faster and creates a better finish because the sandpaper rides directly on the work instead of on a bed of dust. Fresh abrasive is always in contact with the surface and the sanding pad and surface stays cool. Fein sanders can reduce sanding time up to 30%. Job site clean-up is virtually eliminated. Masking doors, windows and vents is not necessary, and jobs are completed faster. Finished products are clean and free of dust, and sandpaper usage is reduced.
