V. Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the HDX-160×10 LEEMIN 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 1.0–2.0 bar 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: It depends on the filter material:

· BN (Glass Fiber) and P (Wood Pulp): Designed for single-use only. Cleaning may damage the media structure and

 compromise filtration efficiency.

· W (Stainless Steel Woven Mesh) and V (Stainless Steel Sintered Mesh): Can be cleaned and reused under 

certain conditions (e.g., ultrasonic cleaning or backwashing). Please consult our technical team for proper 

cleaning procedures.

  For most applications, we recommend single-use replacement to ensure consistent filtration performance.

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

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

· 1–5μm: For servo valves, proportional valves, and ultra-clean systems.

· 6–15μm: For general hydraulic systems with standard control valves.

· 20–40μm: For high-flow, low-sensitivity applications such as lubrication circuits and return line filtration.

· 50–100μm: For coarse filtration and pre-filtration applications.

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

Q4: What is the difference between the four filter material options?

A:

· BN (Glass Fiber): Highest filtration efficiency, excellent dirt-holding capacity, ideal for fine filtration.

· W (Stainless Steel Woven Mesh): Reusable, high mechanical strength, suitable for high-flow and rough filtration.

· P (Wood Pulp): Cost-effective, adequate performance for standard applications.

· V (Stainless Steel Sintered Mesh): Superior strength, high-temperature resistance, suitable for high-pressure

 and corrosive environments.

Q5: Is this filter element compatible with phosphate ester hydraulic fluids?

A: Yes, provided the correct seal material (FKM/Fluorine rubber) is selected. Phosphate ester fluids are not compatible 

with NBR (nitrile) seals. Please specify your working medium when ordering to ensure proper seal material selection.

Q6: Can this filter element handle 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 and preheating the oil during 

cold starts if necessary.

Q7: What is the maximum operating pressure for this filter element?

A: The maximum operating pressure ranges from 21bar to 210bar, depending on the specific model and filter 

material. Stainless steel sintered mesh (V) variants typically offer the highest pressure resistance. Please verify 

the pressure rating of your selected model before installation.

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

A: When the differential pressure exceeds the bypass valve setting (typically 2.0–3.0 bar), 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: 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).

· Visual inspection revealing media damage or excessive contamination.

· Scheduled maintenance interval has elapsed.

Q10: Does this filter element meet international quality standards?

A: Yes. Our HDX-160×10 LEEMIN Filter Elements are manufactured in accordance with ISO 9001 quality management 

systems and tested to industry standards to ensure reliable beta ratio, dirt-holding capacity, and structural integrity.

Q11: Can I use this filter element in a suction line application?

A: The HDX-160×10 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, 

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.

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.
