Abstract

Presented is a vessel used to enclose the ultrasonic nozzle coating operation of substrates. Previous vessels, using a hood with exhaust to remove the solvent and drug or agent to protect the worker, allowed for air currents which caused the plume of droplets used for coating to drift and lower the transfer efficiency of coatings. This invention separates the coating environment from the exhaust hood environment and allows coating to take place in an air current free enclosure. This device also eliminates the random drifting of droplets, collects the overspray and recycles it for continued coating, and provides an ideal environment for use of low velocity spray plumes and expensive drugs and agents.
