9.6 LABYRINTH ACTIVE CARBONS SECTION
The active carbons section shows a series of flat filters ar-
ranged in a labyrinth to create an air passage on a larger
surface compared to a classic panel and at a lower speed.
A longer contact time between air and activated carbons is
obtained in this way, subsequently increasing the odour ad-
sorption effect and reducing pressure drops.
In addition, positioning the activated carbon battery after the
filters and the FI-FX modules extends their service life. The
panels can be opened to replace the activated carbon only,
thereby containing costs.
