Replacement Pall LCS2B1AH Coalescing Filter Element

LEFILTER interchangeable Pall LCS2B1AH coalescing filter is a high-performance fuel-water separation cartridge engineered as a direct aftermarket substitute for genuine Pall liquid coalescer systems. Designed in line with industrial fuel separation standards, this LCS series coalescing cartridge adopts gradient hydrophilic composite fiber media to remove emulsified water, free moisture and fine solid contaminants from jet fuel, diesel and light hydrocarbon fluids. With fully replicated original dimensional parameters, stainless steel end cap assembly and integrated sealing construction, it realizes plug-and-play installation without vessel modification, delivering long-cycle stable purification for airport fuel stations, refineries and bulk fuel terminal facilities. LEFILTER produces the full lineup of Pall equivalent coalescing filter models listed in the specification sheet to support one-stop matching for all your separation equipment.

Product Introduction

Product Overview

The Pall LCS2B1AH belongs to the classic LCS-AH coalescer subseries, widely applied in Pall vertical fuel filter separators for primary liquid-liquid separation. Distinguished from HH, PXSH and LSS variant models in the same product matrix, the AH suffix stands for standard single-lug stainless steel end cap structure, which matches the original internal positioning and locking mechanism of Pall filter housings perfectly.

The multi-layer progressive hydrophilic fiber structure of LCS2B1AH balances high dirt holding capacity and efficient micro-emulsion breaking capability. It effectively eliminates fuel turbidity, pipeline corrosion and precision instrument abrasion triggered by residual water and particulate pollutants inside hydrocarbon media. Our upgraded replacement element optimizes fiber density layout and integral epoxy bonding craft, reducing pressure drop fluctuation during continuous 24-hour operation and extending service intervals compared with generic low-cost alternatives.

Coalescing Filtration Working Principle

The LCS2B1AH operates with inside-to-out fluid flow and three-stage gradient purification structure:

  1. Outer coarse fiber buffer layer: Captures large rust, sediment and mechanical impurities to prevent local media blinding and evenly distribute incoming fuel flow across the full filter surface.

  2. Middle transition fiber layer: Stabilizes fluid velocity and disperses turbulent flow, creating ideal conditions for tiny water droplet aggregation.

  3. Inner high-hydrophilic precision fiber layer: Adsorbs invisible micron emulsified water droplets suspended in fuel. Under persistent fluid shear force, scattered micro water beads collide and merge into large-diameter water droplets, which separate from hydrocarbon fluid via gravity difference and settle in the housing sump, outputting dry, clean qualified fuel.

Core Structural & Material Advantages

  1. Custom Gradient Hydrophilic Composite Fiber Media

    High-purity borosilicate glass composite fiber with permanent hydrophilic modification, outstanding chemical compatibility with all mainstream light hydrocarbon fuels. Maintains consistent demulsification efficiency under long-term temperature cycling and high-flow scouring without fiber shedding or performance attenuation.

  2. Standard AH Single-Lug Stainless Steel End Caps

    Precision stamped stainless steel end caps replicate the original Pall positioning lug design, ensuring stable locking inside filter vessels and resisting loosening under pressure fluctuation and fluid impact.

  3. Integral Full Perimeter Epoxy Sealing

    End caps, media and internal perforated support tube are fully bonded with corrosion-resistant high-strength epoxy resin, eliminating bypass leakage channels that cause unfiltered fluid short-circuit and failed separation performance.

  4. Epoxy-Coated Perforated Steel Central Support

    Internal anti-rust steel core provides powerful radial anti-collapse support, preventing media shrinkage and deformation under elevated differential pressure during heavy-load continuous operation.
