Ionizing air knife

The Air Knife AK GK belongs to the group of air gates. As the name already indicates, these are ionizers which are supported by air flows. The effectiveness of the Air Knife can be explained by the special design of the air discharge nozzle which creates the so-called ?coanda effect?.





The Coanda Effekt
In contrast to full jet nozzles, with the ?coanda effect? the ionized air comes out of a slotted nozzle producing a flat jet. The special construction of the bottom-side of the Air Knife causes an unilateral reduction in injection (air suction from the atmosphere), thus creating negative pressure so that the ionized air is directed to the material web.

Special features and advantages
Reducing the injection affords the air blast operated Air Knife ionization unit two particularly positive aspects:

The air discharge speed is increased, resulting in increased effective depth. This in turn permits a greater operating distance of the Air Knife to the material web.
The slot jet has a wider angle of dispersion, which is expanded from 24° to 33°. A larger surface is therefore covered with ionizing, neutralizing air.
