Disc sander

摘要

A disc sander having a scroll type vane pump embodied in a shroud enclosing the back side of a sanding disc. The inlet ports of the pump are coupled by a manifold to a location adjacent to the front face of the sanding disc at a location where the sanding dust and debris are generated. A tortious serpentine path is provided about the periphery of the pump housing which reduces pump noise and increases pump efficiency. The fins of the vane pump are provided on the back side of the sanding disc.
