Product Introduction
LEFILTER provides high-performance drop-in replacement for the original FAUDI Y.1-842/5 coalescing filter cartridge. Designed and tested in accordance with EI 1581 aviation filtration standards, this aftermarket coalescer delivers reliable solid contamination removal and micro-water coalescing for fuel and light hydrocarbon processing systems. Fully dimensionally and functionally matched with genuine FAUDI components, it requires no vessel modification or field adjustment, helping users resolve long lead times and high OEM costs while maintaining consistent system filtration stability.
The FAUDI Y.1-842/5 is a widely adopted high-durability coalescing element for aviation fuel depots, refinery fuel handling and industrial liquid purification. In continuous operation, fine suspended particles, emulsified water and oil aerosols can degrade fuel quality, clog pipelines and wear downstream precision equipment. LEFILTER’s Y.1-842/5 replacement adopts optimized gradient fiber media and reinforced structural design, achieving stable coalescing performance under fluctuating flow rates and cyclic temperature changes, ideal for long-cycle industrial operation.
Coalescing & Filtration Working Principle
This FAUDI Y.1-842/5 equivalent filter applies multi-stage gradient interception and droplet coalescence technology. The outer open fiber layer blocks large sediments and scale to prevent early clogging and protect the inner precision media layer. As fluid flows inward, micron-scale water droplets and oil mist are captured by the high-hydrophilic glass fiber network.
Through continuous fluid scouring and molecular adhesion, tiny dispersed droplets collide and merge into large-diameter droplets. Once gravity overcomes fluid suspension force, enlarged water droplets separate and settle into the filter sump, while clean fuel flows downstream. This layered purification method ensures uniform fluid distribution, avoids channeling issues, and maximizes dirt holding capacity throughout the filter service cycle.
Key Structural & Material Advantages
1. Standardized Gradient Glass Fiber Media
Manufactured with aviation-grade hydrophilic borosilicate glass fiber, the media features stable chemical inertness against gasoline, diesel, jet fuel and light hydrocarbons. It ensures consistent particle and water droplet removal performance, resisting media deformation and performance attenuation under continuous working pressure.
2. Reinforced Polyamide End Cap & NBR Sealing System
Glass fiber reinforced polyamide end caps provide excellent structural rigidity and temperature resistance. Equipped with original-standard NBR gaskets, the filter achieves reliable tight sealing under pressure cycling. All mounting interfaces match FAUDI Y.1-842/5 specifications for perfect plug-and-play installation.
3. Epoxy-Coated Steel Support Frame
Built-in epoxy-coated steel central tube delivers strong radial support, effectively preventing media collapse and deformation under high differential pressure. Full hot-melt bonding eliminates glue dissolution and secondary pollution, supporting 24-hour uninterrupted industrial operation.
Industrial Application Range
LEFILTER FAUDI Y.1-842/5 replacement coalescer is widely used in aviation fuel terminals, refinery fuel processing plants, bulk fuel storage depots and industrial light hydrocarbon purification systems. It effectively removes free water, fine solid particles and oil mist, protecting compressors, flow meters, control valves and pipeline systems from corrosion, liquid hammer and abrasion, ensuring stable fuel quality and safe system operation.
Product Replacement Benefits
All Y.1-842/5 filter elements are strictly tested for bubble point, pressure resistance and separation efficiency before delivery, achieving full interchangeability with genuine FAUDI filters. Optimized fiber layout provides higher dirt holding capacity and longer service life than generic alternatives. With stable stock supply and competitive pricing, our aftermarket filters effectively reduce enterprise procurement costs and equipment downtime frequency.
