Abstract: A collapsible spray housing and method of using the housing in electrostatic powder spray operations. The housing is collapsible so that it can be folded and inserted into a conventional cartridge filter type powder recovery system. Separate collapsible housings may be maintained, each interconnected with a respective cartridge filter, dedicated to running one particular color therethrough. A skeletal frame may be employed upon which the various collapsible housings may be inserted and removed between successive runs different colors.
Abstract: An electrostatic paint powder booth apparatus having filters for recovery of overspray powder entrained in the air drawn from the housing in which workpieces are sprayed. The apparatus comprises interchangeable particulate filter systems in combination with alternative airflow paths, allowing for rapid changeover between successive runs of differing colors without intermixing of the different colors.
