Cleaning of a 3D object can be performed efficiently by using ionised air. Ionised air can be produced by a nozzle, air gun or air knife using compressed air. For large installations e.g. car parts or complete car bodies is it more economical to use blower driven blow-off systems. Depending on the application, manual cleaning with a hand gun or automated cleaning can be used.
Example of cleaning bumpers for cars prior to painting with a Typhoon blower driven air knife system.
The anti-static bar produces positive and negative ions which are blown onto the surface by the airknife. The electrons will now be exchanged, which causes the surface to be neutralised and the impurities to be removed. For use in hazardous zones(ATEX), the Typhoon with the P-Sh-N-Ex anti-static bar is approved.
