An air filtration system for an operator environment of an agricultural vehicle including at least one external inlet, a first filtration device having a coarser level of filtration located between the external inlet and an HVAC system, a second filtration device having a second finer level of filtration and an associated blower located between the external inlet and the HVAC system where the air filtration system selectively connects either the first filtration device to the HVAC system blower or the second filtration device and its associated blower to the HVAC system blower and a bypass permanently connects the HVAC system blower and the second filtration device.

An air quality system includes an air precleaner, a filter identification component, and a control module. The air precleaner has a precleaner housing and a filter disposed inside the precleaner housing. The filter identification component is positioned within the precleaner housing at a first position and is mounted on the filter. The control module is positioned within the precleaner housing at a second position and is configured to emit an electrical field and communicate with the filter identification component via the emitted electrical field.

A system (10) for treating the air in the cabin of a vehicle includes a casing, an air conditioning apparatus, a filtering device (16) an RFID tag (28) containing identification information about the filtering device (16). An RFID reader (30) co-operates with the RFID tag (28) to read the identification information. A control unit (32) is connected to the RFID reader (30) and configured for receiving the identification information and for executing predefined operations as a function of the identification information.

A cooling structure includes a fan that suctions gas through an inlet and sends gas, a flow path that connects the inlet and the fan to each other, a foreign matter entry suppression member that suppresses entry of a foreign matter into the flow path through the inlet, and a vibration suppression member set between the foreign matter entry suppression member and the fan and provided to suppress vibration of a rod-like foreign matter caused by rotation of a blade of the fan. The foreign matter entry suppression member includes a plurality of opening portions for suctioning gas into the flow path. The vibration suppression member is constructed to be provided with a plurality of opening portions while it is set in the flow path.

A dust reduction device for a vehicle includes an inlet aperture for receiving airflow created as a result of forward movement of the vehicle. The dust reduction device provides a primary airflow path leading from the inlet aperture to a vehicle opening, and a secondary airflow path leading from the inlet aperture to a ventilation exit. During forward movement of the vehicle, the primary airflow path is substantially blocked by airflow from the secondary airflow path such that airflow from the primary airflow path is provided to the vehicle opening and into the vehicle thereby minimising dust ingress in the vehicle.

An air conditioner for a vehicle includes: a case that forms an air passage; and a filter arranged inside the case. The case has an opening for attaching/detaching the filter. The case has a guide unit provided on an inner wall surface of the case to guide a movement of the filter. The guide unit has a positioning portion to determine a position of the filter in a filter mounted state, and a service portion located between the positioning portion and the opening. The case has a water prevention rib protruding from the inner wall surface so as to extend in a direction intersecting a flow of air at a position upstream of the service portion.

Methods and systems are described for air sanitation in vehicles. The system detects a change in a vehicle occupancy in a vehicle. The system then generates an air curtain zone in the vehicle based on the vehicle occupancy. The air curtain zone includes an air curtain to isolate air within the air curtain zone from a portion of the vehicle. The air curtain zone also includes a vent and an air filter to purify air in the air curtain zone.
