ABSTRACT:
A high volume, low pressure air system for atomizing a fluid, such as paint, includes, among other things, a variable jet venturi induction pump which generates low pressure air for powering one or more atomizing devices, such as spray guns, with the intake of the induction pump being located a predetermined distance away from the atomizing devices so that overspray produced thereby is prevented from being fed along with ambient air into the induction pump. The system also controls the supply of compressed air and can be equipped with a compressed air driven intake fan for turbo charging the ambient air fed to the jet venturi induction pump. A booster source of regulated low pressure air is also coupled to the feedline(s) coupled to the individual atomizing devices to augment the low pressure air generated by the jet venturi induction pump for certain spraying tasks.
