AIR1666A - Performance Testing of Lubricant Filter Elements Utilized in Aircraft Power and Propulsion Lubrication Systems

Details
Document Number: AIR1666A
Revision Number: A
Title
Performance Testing of Lubricant Filter Elements Utilized in Aircraft Power and Propulsion Lubrication Systems
Scope
This SAE Aerospace Information Report (AIR) reviews performance testing parameters for non-cleanable, often referred to as disposable, filter elements utilized in aircraft power and propulsion lubrication systems, including gas turbine engines, propulsion and transmission gear boxes, and constant speed drives and integrated drive generators.

Performance testing is necessary to assure that filter elements retain their functional characteristics under operating conditions. Variation in filter element testing methods and requirements make comparison of performance test results difficult. In order to minimize these problems, this AIR describes standard filter element performance test procedures, allowing both manufacturer and customer a common means to specify, control, and elvaluate filter elements. This document highlights recommended tests and the appropriate test sequence. The methodology discussed should be incorporated in filter element specifications.
