V. Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the R928006916 Rexroth Filter Element?

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

 We recommend monitoring the filter element's differential pressure gauge. When the pressure drop reaches the 

manufacturer's recommended alarm value (typically 1.0 MPa above the initial clean pressure drop), replacement

 is required. Under typical industrial conditions, inspection and replacement every 6 to 12 months or

 after 2,000 to 4,000 operating hours is common.

Q2: Can this filter element be cleaned and reused?

A: No. The R928006916 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 to ensure reliable performance.

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

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

· 1 μm: For ultra-clean systems with servo valves and proportional valves requiring the highest level of protection.

· 3 μm: For high-precision hydraulic systems with sensitive control components.

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

· 12 μm: For medium-duty applications and return line filtration.

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

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

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

A: Yes. The R928006916 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 this filter element and the original Rexroth element?

A: Our R928006916 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 performance 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 R928006916 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, dirt-holding capacity, 

and structural integrity.

Q10: What is the maximum operating temperature for this filter element?

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: Can I use this filter element in a suction line application?

A: The R928006916 is generally designed for pressure line or return line applications. For suction line applications, 

a different filter design with lower pressure drop is typically required. Please consult our engineering team for

 specific recommendations.

Q12: How should unused filter elements be stored?

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

moisture, extreme temperatures, and exposure to corrosive chemicals. Recommended storage temperature is

 below 40°C with relative humidity under 80%. Use on a first-in, first-out (FIFO) basis to maintain freshness.

Q13: 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 follow

 local environmental regulations for disposal. Typically, used elements should be drained of oil and disposed of 

as industrial hazardous waste or sent to authorized recycling facilities.

Q14: Is this filter element suitable for high-viscosity oils?

A: Yes. However, high-viscosity oils may generate higher pressure drops, especially at low temperatures. 

We recommend selecting a filtration precision at the coarser end of the range (e.g., 12 or 25 microns) and 

preheating the oil during cold starts if necessary. Please consult our technical team for specific recommendations.

Q15: How do I know if the filter element needs replacement?

A: Key indicators include:

· Differential pressure gauge reading reaching alarm value.

· System performance degradation (e.g., slower actuator response, increased noise, higher operating temperatures).

· Visual inspection revealing media damage or excessive contamination.

· Scheduled maintenance interval has elapsed.
