Cause | Correction |
Powder air speed too low | The ideal amount of air should be in the range from 4-5 Nm3 |
Fine powder/powder with poor flow properties | Use a powder container with fluid air |
Short periods of high compressed air consumption can cause pressure fluctuations | A compressed air reservoir before the powder plant solves this problem |
Too small cross sections or too small radii in the powder hose routing | The radii must be at minimum150-200mm |
Incorrect ratio between fresh powder and recovered powder | Use fresh powder |
Excessively high/low emissions | Adjusting the coating parameters |
Contaminated injectors | Injectors are often neglected during daily cleaning |
