When air rinsing suits
Air rinsing suits bottles that should stay dry and mainly need loose dust or light debris removed. Ionised air may help where static attracts particles.
When water rinsing suits
Water rinsing suits containers that need a wet internal rinse, visible wash step or more intensive cleaning before filling. Drainage and water quality become important.
Drying and downstream equipment
If a bottle is wet after rinsing, the downstream filler, capper, labeller and coding system may be affected. Rinse-dry systems can be specified where dryness is required.
How to choose
Start with the contamination type, bottle material, target output and utility availability, then shortlist the route that solves the problem with the least process risk.
