RRR Oil Filter Element TR-20230
Products Description
The RRR Hydraulic Oil Filter Element TR-20230 is a high-precision replacement element designed for RRR (3R) hydraulic and lubrication filtration systems. This element is engineered to provide exceptional fluid cleanliness by removing solid particles, sludge, and moisture from hydraulic oils, lubricating oils, turbine oils, and insulating oils .
The TR-20230 features a unique graded density structure created by winding specially treated long fibers under high pressure into a deep filtration configuration . The outer layers capture larger contaminants, while the progressively denser inner layers trap finer particles, achieving filtration precision up to NAS6 level in a single pass . The resin-impregnated cellulose fibers also exhibit strong hydrophilicity, effectively absorbing free and emulsified water from oil systems.


Product features
1. The filter is made of special long fibers, adopts a deep filtration structure, and is processed by high density and high pressure.
2. A high-performance filter with deep and thin crepe structure.
3. Strong adsorption, strong hydrophilicity, high filtration efficiency, fast speed, large dirt capacity, long service life, and easy replacement.
4. Suitable for hydraulic oil, lubricating oil, turbine oil, insulating oil, oil filter, etc.
5. Filtration accuracy: high filtration accuracy, one filter from NAS12 to NAS6-9
