Product Description

Product Overview

This high-performance water filter set (Part Nos. 3100308/ WF2075 & -4058965/ WF2076) is engineered for heavy-duty diesel engines, specifically designed to replace legacy filters in Cummins K19/K38/K50 and ISC/ISL systems. These filters excel in mining machinery, construction equipment, and power generation applications, delivering 98.7% filtration efficiency for particles ≥5 microns (WF2075) and ≥10 microns (WF2076), while integrating DCA4+ coolant additives to prevent corrosion and cavitation.

Constructed with a NanoNet composite media (WF2075) and reinforced cellulose matrix (WF2076), each filter withstands extreme operating conditions (-40°C to 120°C) and maintains consistent flow rates up to 40 L/min. The integrated water drain valve and nitrile rubber (NBR) gasket ensure easy maintenance and leak-free performance under vibration.

Detailed Product Description

Advanced Filtration Technology
These filters employ a dual-stage purification process:

Primary Filtration:
WF2075: NanoNet composite media with hydrophobic coating captures particles ≥5 microns (e.g., rust, sand) and coalesces water droplets for efficient separation.
WF2076: Dense cellulose matrix traps particles ≥10 microns while releasing DCA4+ inhibitors to protect coolant systems from corrosion and scale.
Chemical Protection:
Built-in DCA4+ pellets continuously release inhibitors to prevent cavitation erosion in cylinder liners and heat exchangers, extending engine life by 20%.

Durability & Performance

Thermal Stability: Tested under 1,000 cycles of -40°C to 120°C without housing deformation.
Vibration Resistance: Bonded end caps and reinforced polypropylene housing withstand 10-2000 Hz vibrations typical in off-road machinery.
Chemical Compatibility: Resistant to ethylene glycol-based coolants and biodiesel blends up to B20.

Application Scenarios

Mining Machinery: Protects Cummins K38 engines in  789D haul trucks and PC8000 excavators from abrasive dust and water ingress.
Construction Equipment: Ideal for ISL-powered SY550H excavators and  LG958 wheel loaders, reducing coolant system maintenance costs by 30%.
Power Generation: Ensures clean coolant supply for K50-driven 1.5MW generator sets in standby power applications.

Packaging and Delivery

The water 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 water filters each the customers in a timely manner, minimizing any downtime for vehicle maintenance or repair.
