Abstract

An enclosed booth is provided with a low pressure, high volume air pump that outputs a stream of air for sandblast cleaning. A venturi nozzle having a venturi restriction at the end is positioned at the distal end of a first flexible tube. A second flexible tube has an outlet positioned adjacent to the venturi restriction which therefore creates a vacuum to pull sand media from the reservoir into the airflow and eject it out of the outlet nozzle of the first hose. This provides a low pressure stream of sandblast media for cleaning various parts. A reservoir is positioned at the bottom of the booth which is filled with the sandblast media. After the sandblasting media is output from the outlet nozzle, it falls through a substrate having apertures therein and enters the reservoir again.
