Abstract
This invention relates to a portable upblast cleaning head which makes use of an airless centrifugal blasting wheel for throwing particulate in an upwardly direction against the underside of a horizontally disposed surface. The head includes means for effecting a sealing relation with the surface to be treated and for recovery and air wash separation of the blasting particulate from deposits and residue which are removed by the blasting process. The 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.
