R920016827 Filter Element – High-Efficiency Filtration for Reliable Hydraulic Systems

The R920016827 filter element is a critical component in the pipeline series of fluid transmission systems. Typically installed 

at the inlet filter of hydraulic systems, this element is specifically designed to clean hydraulic oil by removing metallic particles,

 abrasive contaminants, and colloidal impurities from the fluid medium. By doing so, it ensures the reliable and uninterrupted

 operation of downstream equipment—including pumps, valves, actuators, and servo mechanisms—while significantly 

extending their service life and reducing unplanned downtime.

In today's demanding industrial environments, hydraulic systems are subjected to a wide range of contaminants, 

from internally generated wear debris to externally ingressed dust and moisture. Even minute particles can cause abrasive wear, 

orifice blockage, valve stiction, and premature fluid degradation. The R920016827 addresses these challenges through its 

advanced media selection, robust structural design, and rigorous quality control, delivering consistent filtration performance 

across a broad spectrum of operating conditions and applications.

Advanced Media and Structural Design

The R920016827 filter element incorporates a multi-layered filtration architecture that combines three key functional 

components:

1. Filtration Media – The element utilizes premium-grade fiber filter material sourced from the United States, featuring strong

 hydrophobic and oleophobic properties. This advanced media effectively repels water and oil while allowing air and fluid to 

pass through with minimal resistance. The fiber structure is designed to capture contaminants throughout the media depth, 

maximizing dirt-holding capacity and extending service life.

2. Fine Porous Sponge Layer – Imported from Germany, this fine-pored sponge serves as a coalescing and separation layer. 

It effectively prevents oil mist and entrained water droplets from being carried away by high-velocity airflow or fluid flow. 

Small oil droplets that migrate downstream are coalesced on the sponge surface and guided to the lower end of the filter

 element, where they are collected and drained from the filter housing—ensuring that the outlet fluid remains clean and dry.

3. Support Framework – The element features a high-strength, corrosion-resistant skeleton constructed with excellent 

permeability. This framework minimizes flow resistance while maintaining structural integrity under differential pressure 

conditions, ensuring consistent performance even during system pressure fluctuations.

Key Performance Characteristics

The R920016827 filter element is engineered to deliver superior operational performance, characterized by the following

 advantages:

1. Excellent air permeability – The US-sourced hydrophobic and oleophobic fiber media, combined with the high-permeability 

framework, significantly reduces flow resistance and pressure drop. This ensures efficient fluid transmission while minimizing

 energy consumption and heat generation within the system.

2. Superior filtration efficiency – The German fine-pored sponge layer effectively captures oil mist and water aerosols that 

would otherwise bypass the primary media. This dual-stage separation mechanism ensures that even sub-micron droplets

 are removed from the fluid stream, delivering exceptionally clean output.

3. Outstanding air tightness – The junction between the filter element and the housing is sealed with a reliable O-ring sealing 

system (FKM or butyl rubber). This prevents airflow or fluid flow from short-circuiting around the element, ensuring that all 

media passes through the filtration layers. This design also prevents unfiltered contaminants from entering the downstream

 system, maintaining consistent cleanliness levels.

4. Corrosion resistance – The element incorporates reinforced nylon end caps and a corrosion-protected filter skeleton, 

both of which are engineered to withstand harsh operating conditions, including high humidity, chemical exposure, 

and temperature extremes. This robust construction ensures long service life even in demanding environments such as 

offshore platforms, chemical plants, and outdoor construction sites.

5. Long service life – The combination of high dirt-holding capacity, low pressure drop, and corrosion-resistant materials

 extends replacement intervals, reducing maintenance frequency and lowering total cost of ownership.

Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the R920016827?

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

We recommend monitoring the differential pressure (ΔP) across the element. Replace when ΔP reaches 80% of the bypass 

valve setting (typically 1.5~2.0 bar for standard configurations). 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 R920016827 filter element be cleaned and reused?

A: No. The hydrophobic/oleophobic fiber media and the fine-pored sponge layer are depth-type, single-use components. 

Cleaning methods such as backwashing, chemical soaking, or compressed air blowing will damage the fiber structure, 

alter pore sizes, and compromise filtration efficiency. Reusing a cleaned element risks media migration, seal degradation,

 and downstream contamination. Always replace with a new, genuine element.

Q3: What is the difference between FKM and butyl rubber seals, and which is better?

A: FKM (fluoroelastomer) offers excellent resistance to high temperatures, mineral oils, and many chemicals, making it ideal 

for most hydraulic applications. Butyl rubber (IIR) provides outstanding resistance to moisture, steam, and polar fluids, 

and is often preferred for applications involving water-glycol emulsions or high-humidity environments. Both seal options are 

available; please specify your fluid type and operating conditions when ordering.

Q4: What does "1μ-100μ" mean in the filtration accuracy specification?

A: This indicates that the R920016827 is available in multiple filtration grades ranging from 1 micrometer to 100 micrometers

 absolute. The specific grade selected depends on the system's cleanliness requirements and component clearances. 

For example, servo-valve systems typically require 3~6 μm, while general industrial hydraulics can use 10~25 μm. Please 

consult our application engineers for grade selection assistance.

Q5: What fluids are compatible with this filter element?

A: The standard R920016827 is compatible with mineral-based hydraulic oils. For phosphate ester fluids, high-water-content

 emulsions, synthetic esters, or aggressive chemical solutions (acids, alkalis, organic solvents), please contact our technical

 team to confirm media and seal material compatibility. Custom variants with alternative seal materials (EPDM, PTFE, etc.)

 are available upon request.

Q6: Does the element include an integrated bypass valve?

A: This depends on the specific housing configuration. Some filter assemblies include an external or internal bypass valve; 

the element itself may or may not contain one. Bypass valves are designed to open when the element becomes fully clogged,

 allowing fluid to flow and preventing system starvation. However, bypass operation should be avoided as it permits unfiltered 

fluid downstream. Please specify your requirements when ordering.

Q7: What is the significance of the hydrophobic and oleophobic properties?

A: Hydrophobic (water-repelling) and oleophobic (oil-repelling) properties are critical for applications where moisture and oil

 aerosols are present. These properties prevent water droplets and oil mist from wetting the media surface, reducing flow

 resistance and preventing premature clogging. The coalesced droplets are then directed to the lower section of the housing 

for drainage, ensuring that only clean, dry fluid continues downstream.

Q8: Can the R920016827 be used in applications with pulsating flow or pressure spikes?

A: Yes. The element is designed and validated in accordance with ISO 3724 fatigue resistance standards, which verify 

performance under cyclic pressure loading and pulsed flow conditions. The reinforced nylon end caps, corrosion-resistant

 skeleton, and robust pleat bonding ensure structural integrity even under challenging operating conditions.

Q9: How do I identify genuine R920016827 elements and avoid counterfeits?

A: Genuine elements are marked with laser-etched part numbers, batch codes, and quality certification labels. Each element

 includes a test certificate showing bubble-point integrity, burst pressure, and flow-versus-pressure-drop performance. 

We strongly recommend purchasing from authorized distributors or directly from the factory to avoid counterfeit products

 that may compromise system safety and performance.
