ABSTRACT:
This invention relates to a portable blast cleaning unit employing one or more airless centrifugal blasting wheels for throwing particulate against a surface to be treated. By use of separate modules, the cleaning unit can be adapted for side cleaning of vertically disposed surfaces or upblast cleaning of horizontal surfaces. The cleaning unit includes means for effecting a sealing relation with the surface to be treated and for recovering and air washing the blast media to remove the debris generated by the blasting process. The air wash separating means is contained directly in the blasting head so that a completely portable and self-contained unit capable of recycling the particulate is obtained.
