R928006645 2.0040 PWR3-A00-0-M Rexroth Filter Element High Pressure

Product Overview

The R928006645 (type designation 2.0040 PWR3-A00-0-M / 2.0040 H3XL-A00-0-M) is an original Bosch Rexroth high-pressure hydraulic filter element manufactured to DIN 24550 standards. It features multi-layer glass fiber media (PWR3/H3XL) with absolute filtration rating of approximately 3–5 μm, delivering high dirt-holding capacity and low initial differential pressure. Designed for pressure-line or return-line filters, the element offers full interchangeability and can be installed directly into original housings without system modifications. Every unit undergoes rigorous quality control and simulated operating condition verification to ensure consistent delivery of high ISO cleanliness levels, protecting precision pumps, valves, and actuators from contamination damage.

Key Technical Advantages

• Multi-layer glass fiber depth filtration: PWR3/H3XL media of the 5th generation, combined with electrically conductive non-woven material, provides superior dirt-holding capacity and consistently low initial pressure drop, extending oil and element service intervals.
• High collapse strength: Optimized structure for high-pressure systems supports up to 330 bar differential pressure resistance, preventing element collapse in the event of bypass failure or clogging and protecting downstream precision components.
• Precise absolute filtration and high cleanliness: Compliant with ISO 16889 multi-pass testing, the element reliably achieves high cleanliness classes, significantly reducing wear and failure rates of pumps, valves and servo systems.
• Full interchangeability and reliable sealing: Manufactured strictly to DIN 24550 and Rexroth standards, dimensions and interfaces match original housings exactly. NBR seals ensure leak-free performance and simple installation.

Application Areas

Injection molding machines, die-casting machines, metallurgical equipment, mobile machinery, marine hydraulic systems, machine-tool spindle and servo circuits, test stands, and high-pressure hydraulic power units requiring pressure or return-line filtration. Especially suitable for OEM equipment and retrofit projects demanding rapid element replacement and strict oil cleanliness control.

Expert Maintenance Tips

Depressurize the system and thoroughly clean the filter housing interior before replacement to avoid secondary contamination. Ensure the O-ring is intact and correctly seated, then tighten the end cover to the specified torque. Replace the element based on differential pressure indicator readings or system contamination monitoring; do not exceed the recommended pressure drop. Use finer-rated elements for initial flushing of new or overhauled systems. Regularly inspect seals and housing condition for corrosion. Always use compatible hydraulic fluid and maintain temperature and viscosity within recommended ranges to maximize element life and filtration efficiency.
