Ideal design of the powder path ● The inside diameter remains constant and the transition between the different parts of the gun is very smooth. ● These features prevent powder depositions inside the gun and facilitate the cleaning procedures. Result: ● Straight, deposition-free path ● Constant powder output © 2015 by Gema Switzerland GmbH - All rights reserved.

Optimized gun body design ● The OptiGun body has a very regular “drop shape”. ● This strongly reduces the powder accumulation on the gun body during the application process. ● The drop shaped body is very easy to automatically clean with blow-off nozzles in combination with horizontal in/out axis. Result: ● Fast, contamination-free color change © 2015 by Gema Switzerland GmbH - All rights reserved.
