Accessories In order to be best equipped for all applications a broad palette of spcial accessories is available: The flat jet nozzle is used for standard applications and permits very good penetration. The round jet nozzle with central electrode is ideal for coating parts with large surface areas and stands out because it achieves a constant uniform coating thickness. Extensions of 150mm or 300mm for simple coating of three dimensional objects are available. For coating the insides of tubes special extensions of 300mm to 3000mm are also available. We recomment the special metallic powder tube for working with large amounts of unbonded metallic powders.
