The powder hopper contains the powder used for coating. The discharge
blades agitate the powder and keep it in loose condition. The injectors
conveying the powder and the level detectors monitoring the powder level
are installed in the lid of the powder hopper. All materials meet the
highest corrosion resistance and biocompatibility demands.
Fig. 1: Powder hopper HFF01
The powder hopper is approved for the following zone if powder hoses
with guide strips are applied and the earthing resistance is less than 1
MOhm!
Explosion protection Zone
