Air Intake System for a Work Vehicle

A method for operating an air intake system for a work vehicle, the air intake system including a filter assembly having a pre-cleaner and an air filter and an air valve movable between an opened position and closed position, the air intake system further including a blower in fluid communication with at least one outlet port defined in the filter assembly, the method comprising:

• moving the air valve to the opened position when an engine of the work vehicle is running such that an airflow is directed in an intake direction through the air filter and into the engine;
• generating a vacuum with the blower such that particulates separated from the airflow within the pre-cleaner are expelled from the filter assembly through the at least one outlet port;
• continuing to operate the blower once the engine is shutdown;
• and
• moving the air valve to the closed position such that the airflow is directed in a reverse direction through the air filter and into the at least one outlet port.

A work vehicle, comprising:

• an engine;
• and
• an air intake system configured to supply clean air to the engine, the air intake system comprising:
• a filter assembly including a pre-cleaner and an air filter, the filter assembly defining at least one outlet port;
• an air valve movable between an opened position and a closed position;
• and
• a blower coupled to the at least one outlet port via a conduit, the blower being configured to create a vacuum within the conduit such that particulates are removed from the filter assembly through the at least one outlet port,
• wherein, when the air valve is in the opened position, an airflow is directed through the filter assembly in an intake direction through the air filter towards the engine and, when the air valve is in the closed position, the airflow is directed through the filter assembly in a reverse direction through the air filter away from the engine.
