What is the primary purpose of the scavenge oil filter?

The primary purpose of the scavenge oil filter is to remove contaminants from the scavenge oil. In gas turbine engines, scavenge oil refers to the oil that has lubricated various components and is collected to prevent issues such as overheating and component wear. The filter plays a crucial role in ensuring that any debris, metal particles, or other contaminants that accumulate in the oil are effectively trapped and removed. This is vital because contaminants can cause significant damage to precision engine parts, leading to reduced efficiency, increased wear, or even engine failure. By keeping the oil clean, the scavenge oil filter contributes to the overall reliability and longevity of the gas turbine engine’s operation.
