Product Introduction

LEFILTER premium replacement FAUDI DC.7-1093-xx composite filter element is a heavy-duty dual-function filtration solution exclusively designed for large-scale industrial fuel handling systems. Breaking the limitations of standard single-stage filter cartridges and small-size DC models, this DC7-series integrated element combines high-capacity solid pre-filtration and high-efficiency coalescing water separation in one reinforced structure. Fully compliant with EI 1581 aviation-grade filtration standards, the DC.7-1093-xx supports customizable structural and precision parameters via the xx suffix, perfectly adapting to high-flow, high-impurity, long-cycle industrial fuel operating conditions. It features full dimensional and structural compatibility with original FAUDI filter housings, enabling direct drop-in replacement without system reconstruction, making it an ideal upgraded replacement for traditional two-stage separate filtration assemblies in large fuel terminals.

As the heavy-duty flagship model of the FAUDI DC composite series, DC.7-1093-xx differs significantly from compact DC.4-series elements and ordinary K/P/D single-function filters. It inherits the large-dirt-holding advantage of 7-series heavy-duty filters and integrates dual-stage purification capability, solving two major industrial pain points for large fuel systems: frequent clogging caused by massive solid pollutants and incomplete demulsification of trace emulsified water under continuous high-flow impact. This all-in-one design simplifies bulky multi-filter configuration for large-scale stations, reduces pipeline pressure drop, and cuts overall operation and maintenance costs for long-term fuel production and transfer.

Reinforced Dual-Stage Heavy-Duty Filtration Mechanism

DC.7-1093-xx adopts an upgraded thickened dual-gradient composite filtration structure optimized for heavy-load large-flow scenarios. The outermost ultra-thick open fiber buffer layer is engineered to intercept large quantities of rust, scale, sediment and aged oxide impurities in raw fuel. Its high-permeability structure disperses instantaneous high-speed fluid impact, avoiding local media overload and pressure surge common in large-volume fuel transfer processes.

After bulk solid removal, the fuel uniformly penetrates into the inner dense high-hydrophilic glass fiber coalescing layer. The customized high-density fiber network captures micron-level fine particles and stubborn emulsified water droplets that are difficult to separate by ordinary filters. Under sustained large-flow fluid shear and molecular interfacial tension, scattered micro-droplets rapidly collide, aggregate and grow into macroscopic water beads. Gravity-driven complete water-oil separation is achieved, delivering dry, high-cleanliness fuel for downstream large-scale processing and storage systems.

Exclusive Structural & Customizable Advantages

1. Thickened Dual-Layer Heavy-Duty Composite Media

Different from conventional thin composite materials, DC.7-1093-xx adopts double-thickened graded fiber media, greatly enhancing dirt holding capacity and high-flow impact resistance. The outer coarse layer focuses on large-volume solid interception, while the inner precision layer guarantees stable demulsification accuracy. The overall media maintains excellent chemical inertness with jet fuel, diesel and light hydrocarbons, achieving long-cycle stable operation without fiber shedding or efficiency decay.

2. Flexible XX Suffix Customization for Industrial Scenarios

The unique xx suffix supports personalized customization of filtration precision, media thickness and structural density, targeting diverse heavy-load working conditions including high-water fuel, high-sediment raw fuel and ultra-large-flow continuous purification. It provides exclusive tailored purification solutions for large industrial projects, far exceeding the fixed performance of standard non-custom filter elements.

3. Fully Reinforced Anti-Collapse Structure & Integrated Sealing

Thickened glass-fiber-reinforced polyamide end caps and enhanced epoxy-coated steel support tube effectively resist high differential pressure deformation and media collapse under peak large-flow load. Full-circle hot-melt integral bonding and standard industrial NBR sealing eliminate leakage risks and structural fatigue, ensuring reliable 24/7 uninterrupted operation for heavy-duty fuel systems.
