Product Description

Product Overview

This premium-grade fuel water separator filter set (Part Nos. FS1022, FS1003, FS1065, P551022, FS36256, LG9704550125, FS19732) is engineered for diesel engines in heavy-duty trucks, construction machinery, agricultural equipment, and power generation systems. These filters are designed as direct replacements for legacy part numbers, ensuring consistent performance in removing water and contaminants from fuel systems.

Constructed with high-strength polypropylene housing and a glass fiber-cellulose composite media, each filter achieves 99.5% water separation efficiency for droplets ≥30 microns and removes 98% of particles ≥5 microns. The integrated coalescing layer features a hydrophobic coating to accelerate water droplet aggregation, while the anti-corrosive internal components withstand harsh operating environments—from high humidity to extreme temperature fluctuations.

Detailed Product Description 

Core Filtration Technology
These filters employ a three-stage purification process to ensure optimal fuel quality:

Coalescing Stage: Hydrophobic media captures and merges water droplets (≥30 microns) into larger beads, which then settle in the filter's water sump.
Depth Filtration Stage: A multi-layer glass fiber and cellulose matrix traps abrasive particles (5-10 microns), including dirt, rust, and carbon deposits.
Polishing Stage: A fine porous membrane removes sub-micron contaminants (<5 microns) to protect fuel injectors and high-pressure pumps from wear.

The integrated water drain valve allows easy removal of separated water without disassembling the filter, while the polypropylene housing resists cracking under pressure and chemical degradation from diesel additives.

Durability & Performance Testing
Each filter undergoes rigorous validation to ensure reliability:

Flow Resistance Test: Maintains pressure drop ≤0.3 MPa at 120% of rated flow, ensuring consistent fuel supply to the engine.
Dust Holding Capacity: Verified to retain 120 g/m² of ISO 12103-A3 test dust, extending service intervals by 30% compared to standard filters.
Thermal Cycling Test: Exposed to -40°C to 80°C for 500 cycles with no media degradation or housing leakage.

The sealing gasket, made from nitrile rubber (NBR), maintains elasticity across the entire temperature range, preventing fuel leaks even under vibration.

Application Scenarios

Heavy-Duty Trucks: Ideal for 6BT/4BT-powered long-haul trucks, reducing injector maintenance costs by minimizing abrasive wear.
Construction Machinery: Compatible with 3.8L and C Series engines in excavators, wheel loaders, and bulldozers, where dust and water contamination are prevalent.
Agricultural Equipment: Protects 2.8L diesel engines in tractors and harvesters from water ingress in muddy field conditions.
Power Generation: Ensures clean fuel supply for QSB/NT Series generator sets (50-1500 kVA) in standby and prime power applications.

Packaging and Delivery

The  fuel water separator filters are carefully packaged to prevent any damage during transit. They are typically placed in sturdy cartons with appropriate cushioning materials to protect them from impacts and vibrations. Delivery options can vary, and customers can choose from methods such as express shipping for urgent requirements or more cost - effective sea or land freight for larger orders. The delivery process is coordinated to ensure that the fuel water separator filters each the customers in a timely manner, minimizing any downtime for vehicle maintenance or repair.
