Replacement Pall LCS4H2HH Coalescing Filter Element

LEFILTER aftermarket equivalent Pall LCS4H2HH coalescing filter is a heavy-duty liquid separation cartridge customized for high-contamination fuel processing systems, fully interchangeable with genuine Pall filter separator housings. Adopting thickened multi-layer hydrophilic glass fiber composite media, this HH-series coalescer boasts superior dirt holding capacity and outstanding emulsion breaking performance, effectively removing large volumes of solid sediment and stubborn emulsified water from jet fuel, diesel and light hydrocarbon fluids. The exclusive HH double-lug stainless steel end cap design delivers firmer anti-loosening positioning under long-term high-flow pressure fluctuation. LEFILTER manufactures all equivalent Pall coalescing models listed in the specification sheet to support one-stop procurement for aviation depots, refineries and large bulk fuel terminals.

Product Introduction

Product Overview

Pall LCS4H2HH belongs to the heavy-duty HH sub-series of classic LCS coalescer line, differentiated from AH single-lug and PXSH standard variants by its double positioning lug end cap structure. This structural upgrade greatly enhances stability during 24/7 continuous heavy-load fuel transfer, eliminating element shifting caused by fluid impact.

Equipped with thicker gradient hydrophilic fiber media compared to regular LCS models, the LCS4H2HH targets raw fuel with high sediment and high water content. It avoids frequent premature clogging common in standard coalescers, extending maintenance intervals and cutting overall operation costs for industrial fuel purification facilities. Our upgraded replacement element optimizes epoxy integral bonding and internal anti-collapse steel support, maintaining consistent low pressure drop under long-cycle harsh working conditions.

Coalescing Filtration Working Principle

The LCS4H2HH adopts a three-stage thickened gradient progressive filtration system with inside-to-out flow direction:

  1. Outer heavy-duty coarse fiber buffer layer: Intercepts massive rust, oxide scale and mechanical debris, preventing surface blinding and evenly distributing high-speed fuel flow.

  2. Middle reinforced transition fiber layer: Buffers turbulent flow impact and pre-disperses loosely bound emulsions to ease micro-droplet aggregation.

  3. Inner dense hydrophilic precision fiber layer: Captures micron-level invisible emulsified water mist. Persistent fluid shear force pushes scattered tiny water beads to collide and merge into large water droplets, which separate from fuel by gravity and settle at the bottom of filter vessels to produce dry, high-cleanliness finished fuel.

Core Structural & Material Advantages

  1. Thickened Heavy-Duty Gradient Hydrophilic Glass Fiber Media

    Custom extra-thick borosilicate composite fiber with permanent hydrophilic modification, featuring ultra-large contaminant storage capacity. Resists fiber shedding and efficiency attenuation under continuous scouring of high-impurity fuel, compatible with all mainstream aviation and industrial hydrocarbon fuels.

  2. HH Double-Lug Stainless Steel End Cap

    Precision stamped stainless steel end caps with dual positioning lugs, locking tightly inside Pall filter housings to prevent displacement under fluctuating pressure and strong fluid impact.

  3. Full-Perimeter High-Strength Epoxy Integral Sealing

    End caps, filter media and perforated steel support tube are fully bonded with anti-corrosion epoxy resin, completely blocking bypass leakage channels and eliminating unfiltered fluid short-circuit risks.

  4. Reinforced Anti-Collapse Epoxy-Coated Steel Central Core

    Thickened rust-proof perforated steel tube provides powerful radial support, resisting media deformation and collapse when differential pressure rises under full-load operation.
