Why static matters
PET and other plastic containers can hold light particles because of static. Standard air alone may not release the contamination reliably.
How ionised air helps
Ionised air nozzles are used to neutralise static while air flow removes particles. Extraction may be used to capture debris after it is released.
Bottle and nozzle position
Performance depends on bottle presentation, nozzle angle, dwell time and the route used to invert or expose the container opening.
Utility checks
Compressed air quality, pressure, flow and maintenance access should be checked before specifying an ionised air rinser.
