Fraser system removes static contamination

The system was designed to overcome contamination issues directly caused by static-charged particles at the outer entrances of the chassis paint spray lines.

Fraser recommended installing three sets of custom-made ionising gates (for all three paint spray lines) using the 5100 Ionised Air Knives before the entrance of the paint spray line.

The Air Knives were positioned to form an arch over the surface of the vehicle to achieve effective blowing and remove all dust and contaminants prior to spraying, while ionising the air and preventing re-attraction.

Optimisation of the air speed has been achieved by the adjustment of air pressure, which can be varied from one to seven bar and is dependent on the cleaning distance.

The Air Knife works by forcing the compressed air out through a slot at high speed.

The air is ionised as it passes over a static eliminator bar and has the capability of neutralising static electricity on both charged particles and the host surface simultaneously.

The reduction of static electricity and associated contamination positively contributed to the improvement of vehicles cleanness before spraying; eliminated one of the sources of non-quality and increased quality and productivity on the final spraying lines.

The system is fitted with an ionising function monitoring and alarm-signal system.
