Abstract
An abrasive surface treating device includes a gun connected to a pressurized air source, a housing containing a supply of abrasive material, an abrasive delivery line connected to the gun and having an aperture adjacent the housing outlet, a shroud to capture spent abrasive, and a vacuum source to draw spent abrasive and debris from the shroud back to the interior of the housing. The delivery of air at high velocity through the gun draws air through the abrasive delivery line via the aperture and thereby draws abrasive from the housing into the air stream flowing from the aperture to the gun so that the abrasive may be propelled against a work surface. The effective size of the aperture may be changed to alter the flow rate of various abrasive materials. In addition, the gun and abrasive delivery line may be connected to an adapter which, in turn, receives a shroud member having a configuration selected in accordance with the shape of the work surface.
