LEFILTER delivers high-precision, fully compatible replacement coalescing filter for the FAUDI A.6-467 model. Tailored for two-stage filter water separator systems, this aftermarket coalescer meets strict EI 1581 aviation filtration standards. It perfectly matches the original FAUDI size parameters, out-to-in flow direction and sealing structure, enabling direct plug-and-play replacement without any equipment modification. Built with high hydrophilic gradient glass fiber media, the A.6-467 replacement stably removes fine solid contaminants and free water droplets from various hydrocarbon media, solving the problems of long OEM delivery cycles and high purchasing costs for industrial fuel purification systems.
Fuel and gas processing systems are extremely sensitive to micro-impurities and suspended moisture. Tiny water mist and fine particles easily cause fuel quality degradation, pipeline corrosion, compressor liquid hammer and inaccurate instrument readings. As a core first-stage coalescing component of FAUDI filtration systems, A.6-467 is widely used in aviation fuel depots, refinery terminals and industrial light hydrocarbon purification. LEFILTER’s optimized alternative filter adopts upgraded layered fiber structure and anti-collapse reinforcement technology, maintaining stable coalescing efficiency under fluctuating pressure and variable temperature working conditions, ensuring long-term safe and efficient operation of the entire filtration system.
FAUDI A.6-467 coalescing filter adopts scientific gradient layered filtration design, realizing dual functions of impurity interception and micro-droplet polymerization. The outer coarse fiber layer undertakes primary filtration, intercepting large particulate dirt and sediment to avoid rapid blockage of the inner precision layer.
During fluid out-to-in penetration, ultra-fine water droplets and oil mist are captured by the high-density hydrophilic glass fiber network. Under fluid pressure and molecular tension, scattered micro-droplets continuously collide and merge into macroscopic large droplets. The enlarged liquid droplets fall off by gravity and settle in the filter housing collection area, while the fully purified clean medium flows steadily to the downstream separation system, completing professional primary coalescing purification.
1. Aviation-Grade Gradient Glass Fiber Media
Adopting high-purity borosilicate glass fiber with progressive density distribution, the media features excellent chemical stability and super hydrophilicity. It is compatible with aviation kerosene, diesel, gasoline and light hydrocarbon solvents, achieving stable micro-droplet removal effect. The layered filtration structure greatly improves dirt holding capacity and delays blockage cycle, suitable for long-term continuous industrial filtration.
2. Reinforced Glass-Filled Polyamide End Cap & NBR Sealing
The end cap is made of high-strength glass fiber reinforced polyamide material, with precise size consistent with original FAUDI A.6-467. Equipped with high-temperature resistant NBR sealing gasket, it achieves zero-leakage sealing under pressure cycling. The standard installation interface ensures seamless assembly with original filter vessels, no debugging required.
3. Epoxy-Coated Steel Support & Integrated Sealing Process
The internal epoxy-coated steel central tube provides strong radial support, effectively preventing media deformation and collapse under high differential pressure. Full hot-melt integrated sealing eliminates adhesive aging and dissolution risks, avoiding secondary pollution to the medium and adapting to harsh continuous operating environments.

LEFILTER FAUDI A.6-467 replacement coalescer is specially designed for two-stage filter water separator systems. It is widely applied in aviation fuel storage and distribution terminals to ensure fuel meets EI 1581 quality standards. It also serves petrochemical refineries, industrial fuel treatment stations and marine fuel systems, effectively protecting downstream precision equipment from moisture and particle erosion, reducing system failure rate and maintenance costs.
We strictly follow FAUDI original industrial standards for reverse production and batch testing. Every A.6-467 filter passes bubble point test and pressure resistance inspection before delivery, ensuring 100% interchangeability and consistent filtration performance with OEM products. Compared with ordinary generic filters, our upgraded fiber material has stronger contamination resistance and longer service life. We support sufficient spot supply and fast global delivery, providing professional technical selection and after-sales service for all industrial customers.
