Roof-mounted AC system – AC353 G4 narrow

The AC353 G4 narrow results from a further development of the very successful AC310 and unifies the product characteristics of the AC353. Buses with narrow roof radii can also be equipped with the AC353 G4 narrow in the future, e.g., school buses in the USA.
