TOPEP Supply Equivalent Lubricating Oil Filter 6659858A

Product Description

We can provide various types of filter elements. The cost savings compared to expensive OEM brands add to the value.
The lubrication system for Rolls-Royce turbine engines or Auxiliary Power Units (APUs) ensures oil cleanliness, protecting bearings, gears, and turbine components from wear caused by impurities. Function: Filters metal particles, carbon deposits, and impurities from the oil; maintains stable oil pressure; and extends engine service life. Real-World Resilience and the theoretical advantages of filtration translate directly into measurable outcomes in the field. The high dirt-holding capacity of this equivalent element ensures that the machine can complete the cycle without a mid-season filter change. The consistent pressure drop maintained by this filter element contributes to the repeatable cycle times and dimensional accuracy of the finished product. This filter is not just a spare part; it is an insurance policy against unscheduled downtime. Therefore, every batch of Equivalent Lubricating Oil Filter 6659858A units is subjected to rigorous quality control protocols that mirror OEM acceptance criteria.

Filter Structure

An hydraulic oil filter element is typically consists of end covers, sealing rings, inner skeleton, outer skeleton, and filter media.
►End Cover--Be used to seal both ends of the filter media and the filter element channels, to prevent the secondary pollution caused by gas or liquid leakage, and to support the filter media to ensure the normal operation of the oil filter element.
►Sealing Ring--Located at the connection between the filter element and the machine, to prevent the filter element from loosening or oil leakage, ensuring the oil circulation in the hydraulic system normally.
►Inner Skeleton--Serves as a support frame, with high thickness. It is typically custom-made according to working pressure to reduce the resistance caused by uneven distribution of the filter media, withstand pressure differentials, and ensure the verticality of the filter media.
►Outer Skeleton--Serves as a protective frame, with a lower thickness and larger pore size. It is used to prevent the filter element deformation caused by external pressure and impacts, and to provide an additional support for the filter element.
►Filter Media--The core component of a filter cartridge, used to filter impurities, separate substances, and adsorb pollutants. Various materials and specifications are available according to different filter medium and the operating environment.
