INTERNORMEN filter element 01.E.90.10VG.HR.EP

Product Description

INTERNORMEN Filter Element 01.E.90.10VG.HR.EP is a high-performance filtration solution designed 

for hydraulic and lubrication systems. Installed primarily at the system inlet or pressure line, 

it effectively removes solid particulates, metal debris, and colloidal contaminants from fluid media, 

ensuring reliable protection for precision components such as pumps, valves, and actuators.

Engineered with advanced glass fiber / stainless steel wire mesh media, this filter element delivers exceptional

 filtration efficiency with low flow resistance. Its optimized pleated structure provides a large effective filtration area, 

enabling high dirt-holding capacity while maintaining a compact footprint. 

The element is also designed for easy maintenance, featuring simple construction, lightweight assembly,

 and uniform media porosity for consistent performance across varying operating conditions.

ship lock gates, theater lifting stages, automated conveyor lines, and firefighting/service vehicles.

FAQ 

Q1: Can this filter element replace the original INTERNORMEN 01.E.90.10VG.HR.EP directly?

A: Yes. This product is manufactured to exact OEM dimensions, seal types, and performance specifications, 

ensuring 100% interchangeability with the original INTERNORMEN element.

Q2: How do I select the correct filtration rating (1–100 μm)?

A: The choice depends on your system's critical clearances. Use 1–10 μm for servo/proportional valve systems,

 10–25 μm for standard industrial hydraulics, and 50–100 μm for return-line or coarse filtration. 

Contact our technical team for customized recommendations.

Q3: What is the recommended replacement interval?

A: We recommend monitoring the differential pressure. Replace the element when ΔP

 reaches 0.35–0.5 MPa (or as specified by your system manual). Actual service life varies with

 contamination load and operating environment.

Q4: Is this element compatible with phosphate ester hydraulic fluids?

A: Yes. The standard construction materials are compatible with both mineral oils and phosphate 

ester-based fire-resistant fluids. For special fluids (e.g., water-glycol), please confirm with our sales team.

Q5: What is the maximum operating pressure for this model?

A: The element housing assembly supports up to 21 MPa (210 bar). Ensure your filter housing is rated accordingly.

 The element itself is designed to withstand differential pressures up to the housing's bypass valve setting.

Q6: Does the glass fiber media shed fibers into the system?

A: No. The media is resin-impregnated and thermally bonded to prevent fiber migration, 

ensuring clean effluent and protecting downstream components.

Q7: Can I use this element in a return-line filter housing?

A: Yes, as long as the flow rate and pressure rating of the housing match the element's specifications.

 Please verify the bypass valve setting and collapse pressure rating for your specific application.

Q8: Are there any storage or shelf-life considerations?

A: Store in a dry, cool environment away from direct sunlight and extreme temperatures.

 The recommended shelf life is 5 years when kept in original sealed packaging.
