Abstract
An air diverter system for a vacuum excavator is disclosed. In a particular embodiment, the system includes a bag house in communication with a debris tank. In addition, the system includes a filter housing secured to a side of the bag house and a valve housing interposed between the bag house and the filter housing. A valve member is mounted within the valve housing and is configured to rotate about an axis to define at least two different passageways for an air flow. The system also includes a selector for rotating the valve member and selectively aligning the passageway for the airflow between a vacuum pump inlet and either the filter housing or the bag house.
