INTERNORMEN filter element

Product description

INTERNORMEN Hydraulic Filter Elements – High-Precision Filtration for System Reliability

In hydraulic systems, INTERNORMEN filter elements play a critical role in removing solid particles

 and colloidal contaminants from the working medium, ensuring precise control over fluid cleanliness levels.

 This directly enhances system stability, operational safety, and equipment longevity.

With superior filtration performance and broad application compatibility, INTERNORMEN filter elements are 

widely trusted across industries including petrochemicals, metallurgy, power generation, electronics,

 pharmaceuticals, refractories, and firefighting equipment.

Key Features

· Rapid cleanliness achievement – Helps hydraulic systems quickly reach and consistently maintain target 

oil cleanliness grades, reducing commissioning time.

· Extended fluid service life – Effectively slows oil oxidation and degradation, significantly reducing oil change

 frequency and lowering maintenance costs.

· Reduced component wear – Precisely removes damaging particles, minimizing friction damage to bearings, 

valves, pumps, and other critical components, thereby extending overall equipment service life.

· High dirt-holding capacity – Multi-layer composite filter media deliver high filtration efficiency while

 accommodating greater contaminant loads, extending service intervals.

Typical Applications

· Metallurgy – Filtration for rolling mill and continuous casting hydraulic systems, as well as various lubrication units.

· Petrochemicals – Solid-liquid separation and recovery of products and intermediates during refining and

 chemical processing.

· Railway & Power Generation – Lubricating oil and fuel oil filtration for diesel locomotives and generator sets.

· Engines & Construction Machinery – Air, oil, and fuel filters for internal combustion engines; hydraulic oil filters 

and diesel filters for construction equipment, marine vessels, and heavy trucks.

· Special Lifting & Handling Equipment – Firefighting vehicles, truck cranes, winches, blast furnace systems, 

steelmaking plant equipment, ship lock gate operators, theater lift stages and orchestra pits, automated conveyor lines, 

and more.

Frequently Asked Questions (FAQ)

Q1: How do I select the right filtration grade for my system?

A: The filtration grade should be determined based on the clearance requirements of your system's critical components

 (e.g., servo valves, pumps) and the target oil cleanliness level (ISO 4406 or NAS 1638). Our technical team can assist

 with recommendations based on your specific operating conditions.

Q2: What is the recommended replacement interval for INTERNORMEN filter elements?

A: Replacement intervals depend on operating pressure, flow rate, and actual contamination levels.

We recommend monitoring the differential pressure indicator – replace the element when the ΔP reaches the 

specified alarm value (typically 1.0 MPa). Regular oil sampling analysis is also advised.

Q3: Are INTERNORMEN filter elements interchangeable with other brands?

A: Yes, our elements are designed to meet international interchangeability standards. However, 

for optimal performance and reliability, we strongly recommend using genuine INTERNORMEN elements, 

as non-genuine alternatives may compromise filtration efficiency and structural integrity.

Q4: What materials are used in the filter media?

A: INTERNORMEN offers a range of media options including glass fiber, cellulose, and stainless steel wire mesh,

 tailored to different precision requirements and fluid compatibility needs. Please consult our sales team for material

 selection guidance.

Q5: Can these filter elements be used in high-temperature or high-viscosity fluids?

A: Yes, depending on the specific model and seal material. Standard versions support temperatures up to 120°C,

 with high-temperature variants available upon request. For viscous fluids, we recommend selecting elements

 with lower initial pressure drop.

Q6: How should I store spare filter elements?

A: Store in a dry, cool environment, protected from direct sunlight, moisture, and dust. Keep elements in their

 original packaging until use. Avoid stacking heavy objects on top to prevent deformation of the end caps or sealing surfaces.
