Products Description
Hydraulic Oil Filter Cartridge. Hydraulic oil filter elements are the core components for contamination control in hydraulic systems. During system circulation, they continuously remove solid particles, metallic wear debris, fibrous impurities, and gelatinous oxidation products, maintaining fluid cleanliness within the allowable contamination levels required by critical components such as servo valves, proportional valves, piston pumps, and hydraulic cylinders. Filter element performance directly determines system reliability, component service life, and overall equipment operating costs.hydraulic oil filters.
Structurally, a hydraulic filter element typically consists of filter media, end caps, an inner support core, an outer protective sleeve, and sealing elements. The filter media-made from high-precision glass fiber, synthetic fibers, or metal wire mesh-are pleated or wound to provide large specific surface area, high dirt-holding capacity, and low flow resistance. End caps and support cores are manufactured from metal or engineering plastics to ensure collapse resistance and structural rigidity under frequent pressure shocks. Seals are chosen from elastomers compatible with the fluid medium (e.g., NBR, FKM, or EPDM) to prevent any internal bypass of unfiltered oil.Hydraulic Oil Filter Cartridge.
Application Fields
Hydraulic oil filter elements are widely used in construction machinery (excavators, cranes), metallurgical equipment (rolling mills), mining machinery, marine hydraulic systems, injection molding machines, wind turbines, and industrial hydraulic power units. They remove solid particles and gelatinous contaminants to ensure system reliability and performance.

FAQ
Q: How to select the correct filtration rating?
A: It depends on the smallest clearances of critical system components. General guideline: 3–5 μm for servo valve systems, 10 μm for proportional valve systems, and 10–20 μm for general industrial systems. Overly high rating increases pressure drop, while too low rating fails to protect components.
Q: What are the risks of continuing to operate after the differential pressure alarm triggers?
A: The bypass valve opens, allowing unfiltered oil to enter the system and accelerating pump/valve wear. The element may also collapse under excessive pressure, releasing debris into the oil circuit and causing severe equipment damage.
Q: Is new oil clean enough without pre-filtration?
A: New oil is not necessarily clean oil. Drum oil often contains particles introduced during transport and storage. It should be pre-filtered through a separate unit before filling; otherwise, it will quickly contaminate the new element.
