What is hydraulic filter element?
Hydraulic filter element is a product buit into its respective housing in order to lower the contamination in the fluid to the desired value, and then to maintain and stabilize this level during the entire system operating time.
As the core of the filter, it is the filter element which performs the actual filtration and/or dewatering function in the housing. Elements consist of several pleated filtration and support layers which are placed as a cylinder around or inside the stabilizing support tube. These mesh packs are sealed by the end-caps. Depending on the type of filter, flow direction through the filter elements is from the outside to the inside, or from the inside to the outside. Depending on the filter material, the filter mesh pack is encased in an additional outer plastic wrap.

Here are few performance characteristics of high-quality hydraulic filter elements:
- High particle separation via a wide particle size and differential pressure range
- High contamination retention capacity
- High pressure stability and low pressure loss
- Wide selection of filtration ratings
- Wide range of applications
- Extensive model range
- Optimum filter materials for specific applications
How to select filter elements?
- Selection of the filtration rating
We recommend you to observe that the components in a hydraulic or lubricating circuit most prone to contamination determine the oil cleanliness class and therefore the filtration rating for the entire system. On critical applications, we recommend that you separate the hydraulic or lubricating circuits.
- Selection of the suitable filter material
Different element designations, optimised to the respective application, have been generated due to the diversity of application for lubricating and hydraulic filters.
