ABSTRACT:
This invention is a pneumatically driven dry wall sander with the capability to create a vacuum to trap the dust, which is produced during the sanding operation, and then safely eject the dust away from the work site. A pneumatic motor that is operated by air will operate the sander and sanding disk and at the same time operate a set of impellers that create a slight vacuum. The air flow can be regulated so that the speed of the motor can be controlled depending on the specific need of the worker in performing sanding operations.
