Ionizing air guns neutralise static charges on several materials and clean the surface using ionized compressed air. Neutralising the static charges makes it easier to blow-clean the surface and prevents dust and dirt particles from being reattracted. The compressed air used for this purpose must be free from oil and water. The guns are connected to a power unit which supplies the required high voltage. The ES2J and Cobra ionizing air guns have a rugged design and therefore ideal for use in industrial applications.
