Respray of overspray of any atomizable liquid with jet venturi induction pump

摘要

This invention reduces the air pollution associated with spraying of paints, coatings, solvents or pesticides against a surface. Spraying invariable causes bounceback of sprayed solids as well as overspray consisting of bounceback and an aerosol of solids, solvent, and air and is an important source of air pollution. This invention is a resprayer consisting of a jet venturi induction pump located near the front of a spray gun which captures the overspray and a respray nozzle which redeposits the captured material on the work surface.
