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

Targeted FAQ
Q: What does the HH suffix of LCS4H2HH mean?A: HH stands for double-lug stainless steel end cap structure, designed for heavy-duty high-flow systems that require stronger anti-loosening positioning; AH is single-lug standard type, PXSH and H13 represent other length and end cap variants for different housings.
Q: Can LEFILTER LCS4H2HH replace genuine Pall filter cartridges directly?A: Yes, outer diameter, inner diameter, double lug size, fiber layout and sealing structure all strictly follow OEM standards, plug and play without equipment adjustment.
Q: Do you produce all Pall equivalent models listed in the specification chart?A: We manufacture every model code shown on the table, covering full LCS, LSS, CC3LG, CS604LG and NGGC coalescer replacement lines.
Q: What contaminants can this heavy-duty coalescing filter remove?A: It efficiently traps large quantities of solid sediment, rust debris, free standing water and stable micron emulsified water mist in jet fuel and diesel media.
Q: Can you provide customized packaging and logo printing for bulk orders?
A: Neutral export packaging, custom brand logo printing and exclusive long-term supply contracts are available for global energy, aviation and petrochemical industrial clients.
