Product Overview
Faudi 60.644-965/D is a high-flow flagship model in the 60.644 tapered separator series. Compared with smaller-spec Faudi separators, this element features a larger effective filtration area and optimized tapered flow channel structure, which significantly improves fuel passing capacity while maintaining precise water separation efficiency. The unique conical design eliminates the dead filtration zones common in cylindrical filters, ensuring full utilization of the filter media and avoiding premature clogging under high-flow operating conditions.
Our replacement 60.644-965/D adopts high-temperature cured permanent hydrophobic treatment technology, delivering long-term stable water repellency even under continuous high-flow fuel scouring. The integrated one-piece polyurethane end cap structure completely avoids fluid bypass and short-circuit filtration. The upgraded reinforced internal support skeleton strengthens pressure resistance, preventing media expansion, shrinkage and deformation under long-term high-load and pressure fluctuation working conditions. Balancing large flow rate, high separation accuracy and long service life, this element is perfectly suitable for industrial high-volume fuel purification demands.

Working Principle
60.644-965/D follows Faudi’s mature large-flow adaptive tapered hydrophobic separation mechanism:
1. High-flow fuel mixed with coalesced water droplets and fine particulate impurities flows radially outward from the inner core.
2. High-density hydrophobic fiber media firmly intercepts all free water and micro water droplets, preventing water penetration.
3. Dry, qualified fuel quickly passes through the tapered filter layer with ultra-low flow resistance.
4. Trapped water aggregates on the media surface, merges into large water masses, and settles by gravity to complete efficient fuel-water separation.
Key Features
- Large-flow exclusive design: Expanded filtration area for high-throughput fuel systems
- Permanent hydrophobic media: Stable water separation performance, anti-secondary emulsification
- Tapered fluid optimization: Full media utilization, no dead filtration zones
- Integrated full-seal structure: Zero bypass filtration, guarantee full-flow purification efficiency
-High-pressure resistant skeleton: Anti-deformation under long-term high-load operation
- Complete OEM interchangeability: Direct replacement without equipment adjustment

Application Scenarios
60.644-965/D large-flow separation filters are widely used in high-capacity industrial fuel purification systems, including large-scale oil depot fuel refining and transmission, port large-volume fuel bunkering stations, petrochemical finished oil pipeline transportation and high-flow aviation fuel supply systems. As core secondary separation components, they efficiently remove residual free water and fine particles after coalescence, stabilize fuel cleanliness and dryness, and protect downstream large-flow pumps, precision metering instruments and control valves from water corrosion and particle wear.
