SYSTEM FOR CLEANING ACCUMULATION ON POWDER SPRAY GUN

摘要

A system and method for blowing-off accumulated powder coating particles from the nozzle and deflector (114) of an electrostatic powder spray coating gun with a stream of pressurized air directed through a flexible tube (74) which flexes when the pressurized air is pulsed therethrough. In another embodiment, an air ring (90) mounted on the gun directs pressurized air against the nozzle. In another embodiment, pressurized air is deflected from a deflector cap (116) back onto the front face of the deflector and onto the nozzle to blow-off accumulated powder therefrom.
