Product Description

Cummins Fleetguard Fuel Filter 3973233 Fs19732 for Engine Isb Isf Qsb Qsl Serie
Product Overview
This high-performance fuel water separator filter set (Part Nos. 3973233 & FS19732) is engineered for diesel engines in heavy-duty trucks, construction machinery, and power generation systems. Designed as a direct replacement for legacy part numbers, it ensures 95% water separation efficiency (SAE J1985 standard) and removes 98.7% of particles ≥4 microns, protecting fuel injectors and high-pressure pumps from wear and corrosion.
Constructed with a Strata Pore composite media and reinforced polypropylene housing, each filter withstands extreme operating conditions (-40°C to 85°C) and maintains consistent flow rates up to 60 L/min. The integrated water drain valve allows easy maintenance, while the nitrile rubber (NBR) gasket prevents leaks under vibration.

Detailed Product Description
Advanced Filtration Technology
These filters employ a three-stage purification process:
Coalescing Stage: Hydrophobic media merges water droplets (≥20 microns) into larger beads, which settle in the filter's sump for easy drainage.
Depth Filtration Stage: Strata Pore composite media traps particles ≥4 microns, including rust, dirt, and carbon deposits.
Polishing Stage: A fine mesh membrane removes sub-micron contaminants, ensuring fuel cleanliness for high-pressure common rail (HPCR) systems.
The Strata Pore media enhances filtration efficiency by 30% compared to standard cellulose filters, with a dust holding capacity of 120 g/m² (ISO 12103-A3).
Durability & Performance
Thermal Stability: Tested under 500 cycles of -40°C to 85°C without housing deformation.
Vibration Resistance: Bonded end caps and reinforced housing withstand 10-2000 Hz vibrations typical in off-road machinery.
Chemical Compatibility: Resistant to biodiesel blends up to B20 and diesel additives.
Application Scenarios
Heavy-Duty Trucks: Ideal for Cummins ISB 6.7L-powered Foton Aumark trucks, reducing injector maintenance costs by 40%.
Construction Machinery: Protects QSB 6.7L engines in excavators and wheel loaders from dust and water ingress.
Power Generation: Ensures clean fuel supply for QSL 9L generator sets (50-1500 kVA) in standby and prime power applications.
