摘要： A blasting device for directed air with entrained blast media at a work surface includes a frame supporting a reciprocal valve, and an adjustable valve limit switch. A shaft is attached to the reciprocal valve at one end, and is supported via a bearing assembly at the other end with a blast nozzle mounted thereto. Rotation of the reciprocal valve causes rotation of the interconnected blast nozzle such that air with entrained blast media exiting the blast nozzle travels along a path beneath the frame. The frame is supported on wheels, and is moved along a work surface by an operator. A vacuum port is positioned adjacent the work surface for removing spent blast media with entrained debris from beneath the blasting device. The handle may be rotated from end to end for ease of operation to assure that the user may move the blasting device in either the forward or rearward direction along a work surface.
