The health hazards associated with sanding paint or varnish can be prevented. The dust extractor designed for use with Fein's MultiMaster ensures that you can breath easily. The dust is extracted directly through the perforated sanding sheets and additional bore holes in the sanding pad. The result is practically dust-free operation, without presenting a risk to your health or leaving unpleasant layers of dust behind. In addition, sanding sheets will have increased service life.
