Replacement Pall LCS4H1AH Coalescing Filter Element

LEFILTER replacement Pall LCS4H1AH coalescing filter is a high-flow industrial-grade fuel coalescer designed for standard Pall fuel filter separator systems. Optimized for medium and large-flow fuel processing conditions, this LCS4H1AH element adopts high-efficiency hydrophilic glass fiber media and standard single-lug stainless steel end cap structure. It reliably removes fine solid particles, sediment, free water and emulsified water from diesel and aviation fuel, ensuring dry, qualified fuel output for refineries, fuel terminals and aviation fuel depots. All dimensions and performance fully match genuine Pall standards for seamless drop-in replacement.

Product Introduction

Product Overview

Pall LCS4H1AH is a mainstream high-flow model in the Pall LCS-AH coalescer series. Compared with small-flow LCS2 series, the LCS4H1AH features larger media diameter and higher flow throughput, making it the most widely used universal coalescer for industrial fuel separation skids.

Equipped with standard AH single-lug stainless steel end cap, it perfectly locks into original Pall housings without shaking or displacement during long-term operation. The multi-layer gradient hydrophilic fiber structure balances excellent dirt holding capacity and stable demulsification performance, effectively solving fuel emulsification, turbidity and fine particle contamination in conventional fuel systems.

Working Principle

The LCS4H1AH uses inside-to-out progressive coalescing filtration:

  1. Outer coarse fiber layer intercepts large sediment and rust, protecting the inner precision layer from abrasion and early clogging.

  2. Middle gradient fiber layer distributes fluid evenly and reduces flow impact.

  3. Inner high-hydrophilic fiber layer captures micron emulsified water droplets.

  4. Tiny water droplets collide and aggregate into large water beads, separating from fuel by gravity to achieve complete fuel-water separation.

Product Features

  • High-flow LCS4 series size, larger throughput than LCS2 models

  • Standard AH single-lug stainless steel end cap, perfect fit original Pall housings

  • Aviation-grade hydrophilic glass fiber, stable emulsified water removal

  • Multi-layer gradient structure, low pressure drop and long service life

  • Integral epoxy sealing, zero bypass leakage

  • Reinforced internal steel core, anti-collapse under working pressure

  • 100% interchangeable with original Pall coalescer cartridges
