Frequently Asked Questions (FAQ)

Q1: How often should the P835486 filter element be replaced?

A: Replacement frequency depends on system contamination levels, operating pressure, flow rate, and duty cycle. 

The most reliable method is to monitor the differential pressure (ΔP) across the element. Replace the element when ΔP 

reaches 80% of the bypass valve setting (typically 0.5~1.0 MPa for medium-pressure systems). In typical industrial environments,

 this may range from 6 to 12 months; in high-contaminant or heavy-duty applications, more frequent changes may be required.

Q2: Can the P835486 filter element be cleaned and reused?

A: This depends on the media type. The BN (glass fiber), P (wood pulp), and V (sintered mesh) media configurations are

 generally designed for single-use only—cleaning can damage the fiber structure or alter pore sizes. 

The W (stainless steel woven mesh) configuration may be cleanable in certain applications, but we recommend consulting

 our technical team for specific guidance. For critical systems, we always recommend replacement with a new, genuine element.

Q3: What is the difference between the four media types (BN, W, P, V)?

A:

· BN (glass fiber) : Highest filtration efficiency, depth-loading media, excellent dirt-holding capacity—ideal for precision

 hydraulic systems.

· W (stainless steel woven mesh) : Surface filtration, low pressure drop, mechanically robust—suitable for high-pressure

 and washable applications.

· P (wood pulp/cellulose) : Cost-effective, good general-purpose performance—ideal for non-critical industrial applications.

· V (sintered metal mesh) : Extremely high strength, temperature resistance, and chemical compatibility—designed for harsh

 environments and high-reliability applications.

Q4: What fluids are compatible with the P835486?

A: The standard P835486 is compatible with mineral hydraulic oils, phosphate ester fluids, water-glycol mixtures, 

and oil-in-water emulsions. For other fluids—including synthetic esters, biodegradable fluids, or aggressive chemicals—please 

verify media and seal material compatibility with our technical team. Custom seal options (EPDM, PTFE, etc.) are available

 upon request.

Q5: What does the structural strength rating (1.0~21.0 MPa) indicate?

A: The structural strength rating indicates the maximum differential pressure that the element can withstand without 

collapse or permanent deformation. Higher ratings (16.0 MPa, 21.0 MPa) are designed for high-pressure main-line hydraulic 

systems, while lower ratings (1.0 MPa, 2.0 MPa) are suitable for return-line or low-pressure applications. Select the rating 

that matches your system's maximum expected differential pressure.

Q6: Does the element come with an integrated bypass valve?

A: This depends on the specific model and housing configuration. Some filter assemblies include an integrated bypass 

valve within the filter head or housing, while others rely on an external bypass system. The element itself may or may not 

contain an internal bypass. Please specify your housing type and system requirements when ordering.

Q7: What is the significance of the 1~25 μm filtration accuracy range?

A: This indicates that the P835486 is available in multiple precision grades to suit different system requirements. 

Filtration accuracy should be selected based on the most sensitive component in the system:

· Servo-valves and proportional valves: 1~6 μm

· Directional and pressure control valves: 10~15 μm

· Gear and vane pumps: 15~25 μm
