Premium Drop-in FAUDI Y.7-1422/5 Coalescing Filter Replacement | LEFILTER

LEFILTER manufactures high-precision aftermarket coalescing filter element to fully replace the original FAUDI Y.7-1422/5. Designed per EI 1581 6th edition aviation filtration standards, this Y-series coalescer is engineered for high-flow fuel and light hydrocarbon purification. It perfectly replicates the original FAUDI size parameters, out-to-in flow path and sealing performance, enabling seamless plug-and-play replacement without housing modification. With upgraded hydrophilic glass fiber media and enhanced structural stability, it delivers consistent solid-liquid separation performance, helping users cut OEM procurement costs and shorten long lead-time maintenance cycles.

As a high-flow grade coalescing element in the FAUDI Y-series lineup, Y.7-1422/5 is widely deployed in large-capacity fuel terminals and refinery processing systems. It is specially optimized to handle high-volume fluid flow while maintaining stable water removal efficiency, effectively solving common operational issues such as fuel emulsification, pipeline corrosion and downstream instrument blockage. LEFILTER’s optimized Y.7-1422/5 replacement adopts gradient density fiber layout and anti-fatigue structure, ensuring reliable filtration output under long-term continuous operation and fluctuating working conditions.

Advanced Coalescing Filtration Principle

FAUDI Y.7-1422/5 coalescing filter adopts two-stage gradient purification design tailored for high-flow working conditions. The outer coarse fiber layer undertakes bulk pre-filtration, intercepting large particles, sludge and scale to avoid local clogging and ensure even fluid distribution across the entire filter media.

During out-to-in fluid penetration, ultra-fine emulsified water droplets and oil mist are captured by the dense inner hydrophilic fiber network. Under sustained fluid shear force and molecular tension, scattered micro-droplets collide and polymerize into large-diameter droplets. These separated water droplets settle down by gravity and are discharged from the filter sump, while clean hydrocarbon fluid flows steadily downstream. This high-flow adaptive coalescing mechanism guarantees stable purification efficiency without pressure surge or flow attenuation.

Core Material & Structural Advantages

1. High-Flow Aviation-Grade Glass Fiber Media

Adopting high-purity graded borosilicate glass fiber, the media features super hydrophilicity and excellent chemical inertness. It is fully compatible with jet fuel, diesel, gasoline and light hydrocarbon solvents. The optimized fiber opening rate improves dirt holding capacity and flow permeability, perfectly adapting to high-flow industrial purification scenarios.

2. High-Strength Composite End Cap & Reliable NBR Sealing

Reinforced composite end caps enhance structural rigidity and low-temperature resistance. Matched with original-standard NBR sealing gaskets, the filter maintains zero-leakage performance under cyclic pressure changes. All mounting dimensions are 100% compatible with genuine FAUDI filter vessels for error-free installation.

3. Anti-Collapse Support & Integrated Hot-Melt Structure

Built-in rigid support tube provides stable radial pressure resistance, effectively preventing media shrinkage and collapse under high differential pressure. Full automatic hot-melt sealing eliminates adhesive aging and secondary pollution risks, supporting 24-hour uninterrupted high-load operation.

Main Application Scenarios

LEFILTER FAUDI Y.7-1422/5 replacement coalescer is specially designed for high-flow fuel purification systems. It is widely used in large aviation fuel depots, refinery fuel processing lines, bulk fuel storage tank farms and industrial light hydrocarbon separation equipment. It effectively eliminates free water, oil mist and fine impurities, stabilizing fuel quality and protecting downstream compressors, precision meters and pipeline systems from liquid hammer and corrosion damage.

Product Competitive Strength

Every Y.7-1422/5 filter element undergoes strict bubble point test and pressure resistance inspection before delivery, achieving full dimensional and performance interchangeability with original FAUDI products. Compared with ordinary generic filters, our upgraded high-flow media delivers better permeability and longer service life, reducing replacement frequency and system maintenance costs. We support sufficient spot inventory and global fast delivery, providing one-stop technical selection and after-sales service for industrial customers.
