3. Key Product Characteristics

3.1 Superior Air Permeability

The filter element utilizes premium fiber filter media with strong hydrophobic (water-repellent) and oleophobic

 (oil-repellent) properties, sourced from the United States. The media is combined with a high-strength, highly permeable 

support framework that effectively minimizes resistance caused by fluid passage. This optimized permeability

 ensures consistent flow rates while maintaining filtration efficiency, reducing energy consumption and pressure loss 

in the hydraulic system.

3.2 Excellent Filterability

The R920007668 element incorporates a fine-porous sponge structure (based on German engineering standards) that

 effectively prevents oil and water droplets from being carried away by high-speed airflow or fluid streams. As fluid passes

 through, small oil droplets are captured and coalesced within the sponge matrix, migrating toward the lower end of the 

filter element and ultimately collecting at the bottom of the filter housing. This coalescing mechanism ensures efficient

 removal of both particulate contaminants and liquid aerosols in gas/liquid separation applications.

3.3 Reliable Air Tightness

The junction between the filter element and the filter housing employs a precision-engineered sealing ring system that

 guarantees no flow short-circuiting. This reliable seal prevents unfiltered fluid from bypassing the filter element and 

entering downstream directly, ensuring that 100% of the fluid stream passes through the filtration media. 

This is critical for maintaining system cleanliness and protecting sensitive downstream components.

3.4 Corrosion Resistance

The filter element features a corrosion-resistant reinforced nylon end cap and an anti-corrosion treated filter skeleton. 

This robust construction enables reliable operation in harsh working conditions, including:

· High-humidity environments

· Chemically aggressive fluids

· Marine and coastal installations

· Outdoor or unprotected installations

The corrosion-resistant design extends the service life of the filter element and prevents secondary contamination from 

rust or material degradation products.

3.5 Wide Precision Range

Available in filtration precision grades from 1μm to 100μm, the R920007668 series accommodates diverse application 

requirements—from ultra-fine polishing filtration in precision hydraulics to coarse straining in high-flow, low-restriction 

systems.

3.6 Broad Temperature & Pressure Compatibility

With an operating temperature range of –30°C to +100°C and pressure capability up to 210 bar, this filter element performs

 reliably across a wide spectrum of industrial conditions, including cold-start environments and high-temperature continuous 

operation.

5. Maintenance & Operation Guidelines

1. Initial Installation – Verify model number and seal integrity before installation. Ensure the filter housing is clean and free

 of debris. Tighten to specified torque values to achieve proper seal compression.

2. Differential Pressure Monitoring – Install a differential pressure gauge across the filter housing. Replace the element when 

the pressure differential reaches 2–3× the initial clean reading, or when the system's recommended change-out value is 

reached.

3. Regular Inspection – Visually inspect seals and housing connections during scheduled maintenance. Replace any damaged 

or degraded seals immediately.

4. Proper Handling – Avoid dropping or crushing the filter element. Handle by the end caps rather than the media to prevent 

pleat damage.

5. Storage Recommendations – Store spare elements in a cool, dry, dust-free environment in original packaging. Avoid 

exposure to direct sunlight, chemicals, or extreme temperatures.
