Air filtration system for vehicle cabs

摘要

An air filtration system for a vehicle cab has an air recirculation circuit which includes an air recirculation blower arranged in an air recirculation channel system in order to draw air from the cab interior and to blow it back into the cab interior. An air recirculation filter is arranged In the air recirculation flow. In order to reliably avoid contamination of the cab interior during filter changes, the air recirculation filter is located in a portion of an outer wall of the cab roof behind a cover. The cover covers the air recirculation channel system hermetically from the cab exterior. When the cover is opened, the air recirculation filter is accessible from the outside.
