Stained sprayers and high color losses are problems with which all paint plants are confronted. Therefore, we took the challenge of resolving both problems within one device – without compromise. Our solution is CleanGun.
The challenge:
Over the past years, the surface throughput of paint lines has constantly grown. This means that application technology has to adapt supply to a permanently increasing paint demand. This leads to stronger and quicker soiling of pneumatic sprayers. To avoid malfunction and soiling of the parts to be painted, the sprayer has to be regularly cleaned.
Sprayer cleaning has to be carried out rapidly and in accordance with VOC requirements, automatically and with a low need for maintenance, constantly avoiding secondary impurities.
The increasing amount of niche products confronts paint plants with smaller batches and more frequent color changes. Each color change causes color loss that should be compensated.
The solution:
The sprayer is cleaned quickly, reliably and in accordance with VOC requirements.
A mechanical cleaning carried out with brushes under addition of solvent has proven to be the most suitable cleaning procedure. It is above all the low solvent consumption that convinces since it leads to a pure air cap and thus to a low quantity of VOC emissions.
The cleaning is carried out within a closed container in order to avoid secondary impurities and to save time.
The brush is moved without air motor. Therefore, the brush neither needs much maintenance nor 
does it require a high amount of compressed air. The color change is carried out in the same device without reducing cleaning quality or unnecessarily soiling the device.
Of course, the cleaning procedure is automated.
