The invention is in a vacuum driven sander that is appropriate for drywall sanding, that utilizes a vacuum flow pulled therethrough to drive a turbine that includes an adjustable lock mounting through a bearing assembly to an eccentric to turn the eccentric that is connected to oscillate a sanding pad that mounts a section of sanding material, and that vacuum air flow also provides for removing sanded particles off from the sanded surface that are transported through the sander and a connected pipe or hose into a catchment container. The sander housing includes a pole mounting cylinder that projects outwardly from a housing top surface and is ported with equal spaced radial cavities formed around the port, and with a selected pair of cavities to receive each of a pair of stub axles of a pivot collar, providing a first pivot coupling that, along with a second pivot mounting of the collar to the end of a hollow bent tube, provides a universal coupling of the hollow bent tube to the sander body that allows for the pivoting of the sander whereby the sanding surface remains in engagement with the wall as it is moved up and down and across the wall. The hollow bent tube also includes a static discharge electrical connector that receives a female connector fixed to an end of a conductive wire for positioning in a sander pole that is mounted to the bent tube end, with the wire extending the length of the pole wherethrough the vacuum exhaust flow passes and conducts a static electric charge into the vacuum flow.

An air handler draws air from inside a building, optionally from a building space heating system, and expresses that air such that the air travels along the inside surface of a window glazing unit which is susceptible to condensation. The air can be expressed at ambient temperature or with a modest amount of supplemental heat. As the air is expressed onto the window, a convection curtain of relatively warmer air passes adjacent the inside surface of the glass, warming the glass enough that condensation does not form on the glass. The system can be controlled using a sensor, optionally controlled by a computer or other controller, which controls the air flow according to needs sensed at the window. Such computer can be used to provide individualized control of condensation on each of multiple windows. A blower may be used to achieve increased control of rate and persistence of air flow.
