Multi-Functional FAUDI DC.4-362-xx Composite Filter Element | Dual-Layer Pre-Filtration & Coalescing Integration

LEFILTER high-performance replacement FAUDI DC.4-362-xx filter element represents the upgraded composite dual-function solution in the FAUDI filtration family. Different from single-function D-series pre-filters and pure coalescing K/P/MIL elements, this DC-type cartridge integrates solid pre-filtration and micro demulsification into one compact structure. Fully compliant with strict EI 1581 aviation filtration standards, the DC.4-362-xx combines coarse impurity interception and fine water-oil separation, simplifying multi-stage filtration system layout while maintaining full drop-in compatibility with original FAUDI filter housings. With customizable specification suffix design, it adapts to diversified cleanliness requirements, solving the pain points of complicated pipeline layout and high spare part inventory pressure in traditional fuel purification systems.

The FAUDI DC.4-362-xx is defined as adual-purpose composite integrated filter element, uniquely engineered to bridge the gap between D-series protective pre-filtration and standard coalescing filtration. Traditional fuel systems require separate installation of D-type pre-filter and coalescing elements, leading to increased pipeline resistance and more consumable types. The DC.4-362-xx innovatively adopts a dual-layer composite structure, which firstly removes large solid sediments, rust and scale, then performs precise emulsified water breaking and separation in one single pass. Ideal for medium-flow fuel purification systems with limited installation space and comprehensive contamination, it is the optimal upgraded alternative for conventional two-stage filtration combinations.

Innovative Dual-Stage Composite Filtration Principle

FAUDI DC.4-362-xx adopts an integrated two-in-one progressive filtration mechanism, realizing sequential purification without dual-element configuration. The outer robust composite fiber layer acts as an efficient pre-filter barrier, intercepting macroscopic solid impurities and dispersing incoming fluid flow evenly across the entire media surface. This step eliminates local turbulence and premature clogging, protecting the inner precision layer from abrasive damage by large particles.

After preliminary solid removal, the fluid penetrates into the inner high-hydrophilic glass fiber coalescing layer. Micron-scale emulsified water mist, suspended tiny oil droplets and residual fine particulates are fully captured and aggregated. Under stable fluid shear force, scattered micro-droplets collide and merge to form large-diameter water beads, which separate from hydrocarbon media by gravity settlement. The integrated dual-stage design completes solid filtration and water-oil separation in one cycle, greatly improving overall system purification efficiency.

DC Series Exclusive Structural & Material Advantages

1. Dual-Layer Composite Integrated Media

DC.4-362-xx adopts custom dual-density composite fiber material, combining high-dirt-capacity outer pre-filter media and high-precision hydrophilic inner coalescing media. The integrated structure avoids flow resistance increase caused by separate double-element installation, achieving balanced high throughput and full-spectrum contamination removal. The chemically inert fiber formula ensures stable compatibility with jet fuel, diesel, gasoline and light hydrocarbon fluids without fiber shedding or performance degradation.

2. Customizable Suffix Specification Design

The xx suffix of DC.4-362-xx supports flexible customization of filtration accuracy and media thickness, enabling targeted matching for different contamination levels and flow demands. Whether for conventional daily fuel purification or slightly polluted raw fuel treatment, the adjustable structural configuration delivers tailored purification effects, far more flexible than fixed-spec single-function filter elements.

3. Reinforced Integrated Structure & Full Sealing Technology

High-strength polyamide end caps and epoxy-coated steel support tube enhance overall structural stability, resisting pressure fluctuation and fluid impact during continuous operation. Full-perimeter hot-melt integral bonding eliminates gap leakage and secondary pollution risks. The standard NBR sealing system ensures zero-leakage installation, perfectly adapting to long-cycle 24-hour industrial continuous operation.
