Filter Elements for Offline and Bypass Filters

At the heart of the STAUFF Offline and Bypass Filter Unit is the unique microfilter element. This filter is designed with a radial flow path.

The element is constructed with 0,5 micron media and is therefore able to remove the smallest particles (silt) from the oil.

The filter material is composed primarily of cellulose, which is applied by a special wrapping method. Glass Fiber and water absorbing elements with 3-20 µm are available on request.

The cellulose material is capable of retaining solid particles and absorbing water. This helps to prevent chemical deterioration of the oil and the formation of various acids and sludge.

Hydraulic cylinder extension for example, can draw air, solid contamination particles and water vapor into the oil reservoir.

The water vapor condenses due to temperature changes and causes not only oxidation of the oil, but can also lead to serious mechanical wear in the system.
