A rotatingly driven filter element for filtering incoming air is to be arranged in a machine part upstream of an intake chamber of a cooling system or of a combustion air distribution device of an internal combustion engine of a self-propelled working machine. The filter element has a rim area with a circumferentially extending section provided with air guiding elements oriented toward and projecting into the intake chamber. The rim area, when the filter element is arranged in the machine part, is positioned at a minimal spacing relative to the machine part and an air gap is formed between the rim area and the machine part. The air guiding elements guide purified inflow air out of the intake chamber into a region of the air gap to effect a sealing action of the air gap.

A system for treating ambient air is provided. The system includes a flow control structure disposed on a vehicle. The flow control structure is adapted to control flow of ambient air received during movement of the vehicle. The system further includes an actuator operatively coupled to the flow control structure. The actuator is adapted to movably adjust the flow control structure. The system further includes a controller disposed on the vehicle and communicably coupled to the actuator. The controller is configured to control the actuator based on at least a quality of ambient air. The system further includes an air treatment component for selectively receiving ambient air from the flow control structure. The air treatment component is adapted to treat at least one pollutant present in ambient air.

In one aspect, an air intake system for supplying air to an engine of a work vehicle may include a cooler box having a first wall and a second wall, with the first and second walls at least partially defining a chamber within the cooler box. The air intake system may also include a screen defining at least a portion of the first wall of the cooler box. Furthermore, the air intake system may include an air filter assembly defining at least a portion of the second wall of the cooler box. The air filter assembly may be configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly. The air exiting the cooler box through the air filter assembly may be supplied to the engine for combustion.

The present teachings provide for a radiator fan assembly including a fan, a shroud, a flapper door opening, and a flapper door. The shroud defines a fan opening aligned with the fan through which airflow from the fan passes. The flapper door opening is defined by the shroud. The flapper door is pivotally mounted at the flapper door opening. The flapper door includes a main body and an air guide extending from the main body.

A filter arrangement for a liquid-conducting system, preferably a cooling circuit of an engine, includes a filter housing with an inlet and an outlet for liquid flowing along a flow path through the filter housing. A filter is arranged in the filter housing in the flow path of the liquid for filtering out dirt particles from the liquid. A collecting chamber is arranged upstream of the filter and into which dirt particles which are filtered out by the filter drop because of gravity when liquid no longer flows through the filter housing, wherein the collecting chamber forms a dead space, and therefore dirt particles located in the collecting chamber are not entrained by liquid flowing through the filter housing.
