摘要： A method includes providing at least one filter element in a test rig. The at least one filter element separates a clean side from a dirty side within the test rig. The pressure differential between the clean side and the dirty side is measured. The pressure differential between the clean side and the dirty side is increased by filtering particulate matter and fluid from an air flow within the test rig. The at least one filter element is cleaned. The previous three steps are repeated to replicate the conditions the at least one filter element is subjected to during substantially the entire life cycle of the at least one filter element.
