An air filter system for a utility vehicle, comprising:
- a filter housing;
- a coarse filter on an inlet side and accommodated in the filter housing;
- a fine filter arranged downstream in a filter operating direction of an airflow to be cleaned;
- a cleaning arrangement accommodated in the filter housing for purging dirt particles separated at least in the fine filter counter to the filter operating direction;
- a safety filter redundantly arranged downstream of the fine filter inside the filter housing in the filter operating direction;
- and
- an air outlet nozzle oriented in a direction of a filter surface of the fine filter, wherein the air outlet nozzle feeds into a housing chamber region located between the fine filter and the safety filter in the direction of the filter surface, and wherein the air outlet nozzle extends through the safety filter into the housing chamber region.
