Abstract
A low profile vacuum driven sander as is appropriate for drywall sanding, with a vacuum flow pulled therethrough to drive a turbine whose turning through an eccentric provides an oscillating movement to a sanding pad that releasably mounts a section of sanding material thereto, and with that vacuum air flow also removing sanded particles and dust off from the sanded surface and transports it through the sander and a connected pipe or hose into a catchment container. The sander housing includes a pair of spaced inlet ports that are formed to provide a balance air flow into a turbine chamber that contains a turbine that is journaled axially to bearings of a bearing assembly maintained in a bearing assembly cavity of a center stanchion, with the bearing assembly cavity separated from the vacuum air flow and is ported to without the sander housing for providing, when the sander is operating, a fresh air flow into the bearing assembly cavity, prohibiting dust as is entrained in the vacuum air flow from entering the cavity as could interfere with bearing functioning and result in a loss in sander efficiency and malfunction. The turbine is preferably formed from upper and lower sections that are of different heights for facilitating assembly of the bearings in the bearing assembly cavity to, in turn, allow the sander housing to be formed having a low profile, and includes a coupling assembly of the sander body to a vacuum tube that can be freely adjusted and locked in place at a desired angle to a surface to be sanded.
