Lube Filtration Overview
Filter Media At Donaldson, we have a variety of lube filter medias available to meet the most stringent of engine lube system design requirements. Donaldson engineers have a history of developing media technology that exceeds application cleanliness and service life expectations. In fact, Donaldson was the first company to introduce fully synthetic media to the engine lube market in the early 1980’s. This media is now commonly adopted for extended life or enhanced engine protection needs. New lube media types are constantly under evaluation in our internal laboratories and in controlled field testing. If you have a specific application requirement, please contact Donaldson to see if there are additional media options to better suit your application.
Synteq ™ Synthetic Media Donaldson’s fully synthetic lube filter media is constructed of layered, micro-fiberglass synthetic fibers. It provides enhanced durability for extended drain intervals while maintaining or improving efficiency and capacity. Synteq lube media offers lower restriction. Low restriction allows better flow which ensures component protection over a larger range of engine conditions.

Cellulose Media This traditional lube filter media is most commonly a pleated cellulose base material. This media effectively combines an application’s efficiency and capacity requirements while maintaining cost effectiveness. As oil flows through the media, large contaminants are captured on the surface of the filter while smaller contaminant becomes embedded in the underlying media layer. This media provides the consistency of layered fibers to capture coarse contaminant coupled with the affordability of cellulose to deliver an efficient and effective performance alternative to traditional cellulose media. This media is a blend of cellulose and synthetic media technologies. It utilizes the best attributes of both media fiber types to achieve an improved cost to performance ratio for more demanding applications than a cellulose only media can achieve.
