03. Technical Analysis & Performance
How the FAX-400X10 Protects Hydraulic Systems
A hydraulic return filter is a critical component installed in the return line of a hydraulic circuit to capture wear debris from valves and cylinders before the fluid re-enters the reservoir. The FAX-400X10 utilizes a Beta Ratio optimized for 10-micron particles, effectively removing silt and metallic shavings that cause catastrophic pump failure. By maintaining ISO 4406 cleanliness levels, this filter prevents "stiction" in sensitive proportional valves used in XCMG graders.
Why Choose Our Replacement Filters?
- Media Structural Integrity: Unlike low-cost paper alternatives, our glass fiber media resists "pleat bunching" under high flow rates.
- Precise Fitment: Dimensions are calibrated to ensure a zero-clearance seal within the Leemin-style housing, eliminating unfiltered oil bypass.
- Cost-to-Performance Ratio: We deliver OEM-grade filtration efficiency at a significant reduction in total cost of ownership (TCO) compared to branded dealership parts.

06. FAQ (Frequently Asked Questions)
A: It serves as the primary return line filter, capturing contaminants generated by cylinders and motors to prevent pump cavitation and component wear.
A: Yes. The inorganic glass fiber media and NBR seals are compatible with most synthetic, biodegradable, and petroleum-based oils.
A: When the back-pressure indicator reaches the "red" zone (0.35 MPa) or during scheduled maintenance every 500-1000 operating hours.
A: It provides a balance between high-level protection for sensitive valves and maintaining a manageable pressure drop, preventing abrasive wear in pumps.
A: The FAX-400X10 is the element only. The bypass valve functionality is typically integrated into the Leemin filter housing head.
