Abstract
An air assisted electrostatic liquid spray nozzle assembly having a relatively long elongated nozzle body with a spray tip and surrounding air cap disposed at a downstream end of the nozzle body. The spray nozzle assembly includes an upstream electrode for connection to a high voltage electric source, an elongated feed tube, an electrically enhancing stinger, and the spray tip which are secured and retained by the air cap in electrically conductive relation to each other such that liquid passing through liquid passages of the electrode, feed tube, stinger, and spray tip is discharged in an electrostatically charged pattern of liquid particles. The air cap is removable to permit easy removal and replacement of the spray tip, stinger, and liquid feed tube.
