The PTI 7578659AM is an FAA-PMA approved cleanable oil filter element used in turbine aircraft engine lubrication systems. It is designed for Pratt & Whitney Canada engines including PW100, JT15D, and PT6T/PT6B series applications.

The element uses a pleated stainless-steel mesh filtration media, allowing it to be cleaned and reused multiple times instead of being replaced after each service cycle. This construction provides high strength, stable flow characteristics, and resistance to high temperatures and aggressive turbine engine oil environments.

It is installed inside a dedicated engine oil filter housing and plays a critical role in removing metallic particles and contaminants from engine oil, supporting both lubrication protection and engine condition monitoring during maintenance inspections.
