Endoscopes need to be dried if they are not going to be used again immediately, because bacteria growth in a wet endoscope is far higher than in a dry endoscope. The drying process consists of funnelling dry air through the endoscope cabinet for two hours under a maximum pressure of 0.5 bar.

Actiflow assisted Van Vliet with the design of the airflow through the cabinet to attain unidirectional flow with no areas of back-flow.
