Donaldson Vacuator Valves

Vacuator valves are the rubber duckbill valves at the bottom of an air cleaner that let collected dust fall out under the pulsing of the intake while staying shut against airflow. When one hardens or splits, dust either accumulates inside or unfiltered air is drawn in past it.

Valves are sized to the housing. Search by Donaldson part number, or give us the number on the air cleaner.
