Air Knives

Arrow-brand-red Image

The main function of an airknife is to remove low-value fractions from the material stream. It is typically installed at a conveyor junction and consists of an input air volume channelled through an adjustable nozzle, working in conjunction with an extraction hood, all mounted inside a single enclosure.

The airknife is employed to remove lightweight unpickable items such as paper, plastics and foil from the material stream. The input air creates a high-velocity airstream through which the falling material has to travel. The lighter material fractions are blown or separated from the falling material and are captured by the extraction hood and conveyed away. The heavier material is unaffected by the incoming airstream and falls onto the conveyor below.
