V. Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the R928006764 Rexroth Filter Element?

A: The replacement interval depends on operating conditions, oil cleanliness, and contamination ingress rates.

 We recommend monitoring the differential pressure gauge. When the pressure drop reaches 1.0 MPa above

 the initial clean pressure drop (or the alarm value specified by your system manufacturer), replacement is

 required. Under typical industrial conditions, we recommend inspection every 6 to 12 months or after

 2,000 to 4,000 operating hours.

Q2: Can this filter element be cleaned and reused?

A: No. The R928006764 Rexroth Filter Element is designed for single-use only. Cleaning glass fiber media 

may damage the fine fiber structure, reduce filtration efficiency, and cause media migration, 

leading to secondary contamination of the system. Always replace with a new element.

Q3: How do I select the correct filtration precision for my system?

A: Filtration precision selection depends on the sensitivity of system components:

· 1–3 μm: For servo valves, proportional valves, and ultra-clean systems.

· 6–12 μm: For general hydraulic systems with standard control valves.

· 25 μm: For high-flow, low-sensitivity applications such as lubrication circuits.

  Please consult your system manufacturer's specifications or contact our technical team for assistance.

Q4: Is this filter element compatible with Rexroth filter housings?

A: Yes. The R928006764 is designed to meet Rexroth's original specifications. To ensure compatibility,

 please verify the model number, dimensions (outer diameter, inner diameter, length), seal type, 

and bypass valve rating. Our team can provide cross-referencing support.

Q5: What is the difference between your R928006764 and the original Rexroth element?

A: Our R928006764 Rexroth Filter Element is manufactured using equivalent high-quality glass fiber media

 and premium sealing materials, meeting or exceeding original performance specifications. It offers reliable, 

consistent filtration at a competitive price with faster delivery times.

Q6: What does βx ≥ 100 mean?

A: The beta ratio (βx) indicates filtration efficiency. βx ≥ 100 means that for every 100 particles larger

 than the rated micron size entering the filter, 99 or more are captured. This corresponds to a minimum

 filtration efficiency of 99%, providing excellent protection for system components.

Q7: Can this filter element be used with water-glycol or phosphate ester fluids?

A: Yes, provided the correct seal material is selected:

· NBR (Nitrile): Suitable for mineral oils and water-glycol emulsions.

· FKM (Viton): Required for phosphate ester fluids and high-temperature applications.

  Please specify your working medium when ordering to ensure proper seal compatibility.

Q8: What happens if the filter element bypass valve opens?

A: When the differential pressure exceeds the bypass valve setting (typically 2.0 MPa), the valve opens to 

allow oil flow around the filter element, ensuring system lubrication but allowing unfiltered oil to circulate. 

This can accelerate component wear. If the bypass opens frequently, check for excessive contamination and 

replace the filter element promptly.

Q9: Does this filter element meet international quality standards?

A: Yes. Our R928006764 filter elements are manufactured in accordance with ISO 9001 quality management 

systems and tested to ISO 16889 (multi-pass performance testing) to ensure reliable beta ratio and dirt-holding capacity.

Q10: Can I use this filter element in high-temperature environments?

A: The standard operating temperature range is -10°C to +110°C. For temperatures exceeding 110°C, 

we recommend selecting high-temperature seal materials (e.g., FKM) and consulting our engineering 

team to confirm suitability for your specific application.

Q11: How should unused filter elements be stored?

A: Store filter elements in their original packaging in a cool, dry, dust-free environment. Avoid direct sunlight, 

moisture, and corrosive chemicals. Recommended storage temperature is below 40°C with relative humidity below 80%.

 Use on a first-in, first-out (FIFO) basis to maintain freshness.

Q12: How do I properly dispose of used filter elements?

A: Used filter elements may contain hazardous contaminants such as heavy metals or oil residues.

 Please dispose of them in accordance with local environmental regulations. Typically, used elements

 should be drained of oil and treated as industrial hazardous waste or sent to authorized recycling facilities.
