R920007668 filter element

Product introduction

The R920007668 filter element is an essential component in pipeline systems for fluid transmission media. 

Typically installed in the inlet filter of hydraulic systems, this filter element is designed to clean hydraulic oil and 

remove metal particles, abrasive dust, and other contamination impurities from the fluid medium—ensuring the normal,

 reliable operation of downstream equipment.

As a high-performance filtration solution, the R920007668 combines advanced media technology with robust structural 

design to deliver consistent filtration efficiency across a broad spectrum of operating conditions. Its versatility extends

 beyond hydraulic applications to pharmaceutical, food and beverage, petrochemical, electronics, and chemical processing

 industries.

3. Product Characteristics

3.1 Superior Air Permeability

The filter element utilizes advanced fiber filter media with strong hydrophobic and oleophobic properties, sourced from the 

United States. This media is combined with a high-permeability, high-strength framework that minimizes flow resistance 

while maintaining structural integrity. The result is efficient filtration with low pressure drop, reducing energy consumption 

and system load.

3.2 Excellent Filterability

The element incorporates fine-porous sponge media (German technology) that effectively prevents oil and water from 

being carried away by high-velocity airflow. As fluid passes through, small oil droplets are captured and coalesced within 

the sponge structure, gathering at the lower end of the filter element and eventually settling to the bottom of the filter 

housing for easy removal. This design ensures comprehensive separation of both solid and liquid contaminants.

3.3 Reliable Air Tightness

The interface between the filter element and the filter housing is sealed with high-performance O-rings that ensure zero

 bypass leakage. This air-tight sealing prevents airflow short-circuiting and ensures that all fluid passes through the filter media, 

effectively blocking contaminants from directly entering downstream components without proper filtration.

3.4 Corrosion Resistance

The filter element features a corrosion-resistant reinforced nylon end cap and corrosion-resistant filter framework. 

This robust construction enables reliable operation in harsh working conditions, including exposure to moisture, chemicals, 

and temperature fluctuations. The nylon material provides excellent dimensional stability and chemical resistance,

 extending service life in demanding environments.

3.5 High Dirt-Holding Capacity

The pleated design maximizes filtration surface area within a compact element volume, providing extended dirt-holding

 capacity and longer service intervals. This reduces maintenance frequency and lowers overall operating costs.

3.6 Temperature & Pressure Stability

Engineered to withstand operating temperatures from –30°C to +100°C and pressures up to 210 bar, the R920007668 maintains 

stable filtration performance across a wide range of hydraulic and process conditions.

7. FAQ (Frequently Asked Questions)

Q1: What is the R920007668 filter element used for?

A: The R920007668 is a versatile filter element used primarily in hydraulic and lubrication systems to remove particulate 

contaminants. It also serves pharmaceutical, food and beverage, oil, electronics, and chemical industries for liquid pre-filtration

 and purification applications.

Q2: What filtration precision options are available?

A: The R920007668 series offers precision grades from 1μm to 100μm. Please specify your application's cleanliness

 requirements when ordering to ensure optimal performance.

Q3: What is the maximum operating pressure for this filter element?

A: The operating pressure range is 21 bar to 210 bar (300 to 3,000 psi), accommodating most industrial hydraulic and process 

systems.

Q4: Are the filter elements washable and reusable?

A: No. The r920007668 filter elements are disposable and should be replaced when clogged. Attempting to clean them may 

damage the delicate fiber media and compromise filtration efficiency.

Q5: What is the difference between FKM (fluororubber) and NBR (nitrile) seals?

A: FKM seals offer superior high-temperature resistance and chemical compatibility, suitable for demanding applications.

 NBR seals are cost-effective for general hydraulic oil applications at standard temperatures. Choose based on your operating 

conditions.

Q6: Can this filter element be used with synthetic hydraulic fluids?

A: Yes, but media and seal compatibility should be verified for specific synthetic formulations. Please consult our technical 

team with your fluid specifications.

Q7: How often should the filter element be replaced?

A: Replacement intervals depend on system contamination levels and operating hours. Monitor the differential pressure

 indicator—when pressure drop reaches the recommended change-out value, replacement is required. Under normal conditions, 

elements typically last 6–12 months.

Q8: What does the hydrophobic and oleophobic media do?

A: This specialized media repels both water and oil droplets, preventing them from being carried downstream by high-velocity

 airflow while still allowing efficient particle capture. This is critical for applications where liquid carryover must be minimized.

Q9: Is this element compatible with high-viscosity fluids?

A: Yes, but initial pressure drop will be higher with increased viscosity. For high-viscosity applications, we recommend selecting 

a coarser precision grade and consulting our technical team for flow optimization.

Q10: What industries commonly use this filter element?

A: The R920007668 is used in hydraulic systems, pharmaceutical manufacturing, food and beverage processing, oilfield 

operations, electronics manufacturing, and chemical processing—any application requiring reliable particulate removal from 

liquids.

Q11: What is the temperature rating of this filter element?

A: The continuous operating temperature range is –30°C to +100°C. For high-temperature applications exceeding 100°C, 

specialty media options are available upon request.

Q12: Can this element be retrofitted into existing filter housings?

A: Yes. The R920007668 is designed to standard dimensions compatible with most common filter housings. Please confirm your

 housing specifications and installation dimensions before ordering.

Q13: What quality certifications do your filter elements meet?

A: Our elements are manufactured to meet or exceed applicable ISO standards. Factory test reports, material certificates, 

and dimensional inspection records are available upon request.

Q14: How is the filter element constructed to prevent bypass leakage?

A: Precision-molded sealing grooves and high-performance rubber O-rings create a tight seal between the element and housing.

 This prevents unfiltered fluid from bypassing the media and entering downstream components.
