ABSTRACT:
A hand held wand with forefinger and thumb contours (75) so arranged that upon grasping the wand the index finger is automatically positioned over an on/off switch (74). The wand and switch communicates with a motor/fan housing (39) by way of electrical conductors (81) encased in a thin profile hose (80). A device specifically used to remove eraser debris from a drawing surface. The positioning of the wand over a given task and applying power to the motor/fan is accomplished with the use of one hand. The wand (73) is equipped with a hanging ring (70) for wand positioning when not in use. The hanging ring, (70) when placed on the ring hook (71), holds the wand in an upright position which is convenient for the operator during his or her course of work. Airborne eraser debris is carried through the hose (80) to the motor/fan housing (39) and deposited in an air filter bag (45) enclosed within an air filter bag chamber (64). The motor/fan housing (39) has multiple modes of attaching to the underside of any work station.
