The majority of plastics used today are very susceptible to the formation of electrostatic charges on the surface. The result of this is that the surfaces are strongly attractive to particles floating in the surrounding air. These adhering particles must be removed before painting.

Dirt is difficult to remove from three-dimensional or structured surfaces using conventional methods. Components such as goods carriers, which are used continuously in circulating operation, are usually also difficult to clean on account of their geometry.

The dynamic ionisation station has been developed especially for these applications. The goods carriers with the three-dimensional workpieces usually pass through the ionisation station standing on, or suspended from conveyor systems. Ionisation electrodes installed in the inlet and outlet generate positively and negatively charged ions, which are transported by the flow of air to the plastic surfaces. The static surface charges are neutralised as a result.

The rotary cleaning nozzles located in-between remove adhering particles from the surfaces of the workpieces using cleaned compressed air. Dust and material particles are blown away by a pulsating air flow from different directions due to the rotation of the nozzles. This highly effective method enables even dirt on shaped parts to be cleaned off reliably. The particles cleaned off in this station are fed to a filtered extraction device by targeted air guidance.
