3. Flat jet nozzle with vented centre electrode
The air-cleaned flat jet nozzle atomizes and charges the powder. The slotted opening forms
the powder cloud in such a way that an oval spray pattern is achieved.
The powder is charged by means of a central electrode. The high-voltage, generated inside
the gun, is conducted via the black contact ring of the nozzle holder to the centre electrode.

In order to prevent powder from sintering on the electrode, the latter is cleaned by com-
pressed air during the spraying process. For this purpose rinsing air is fed via the small hole
in the black contact ring in the nozzle holder into the hole in the electrode holder.
Rinsing air control is described in the corresponding Gun Control Operating Instructions.
