Cotton/semi-chemical cellulose oil filter element(CJC)
CJC filter insert are produced from unbleached cotton / semi chemical cellulos.
C.C.JENSEN is the global leader in offline oil filtration with decades of experience on the worldwide markets. The CJC filter inserts are produced of 100% natural cellulose fibres from sustainable resources (cotton fiber and/or semi-chemical cellulose) - no metal, no plastic, no chemicals.
SINFT can produce two types of retrofits for CJC filter inserts. SINFT Filter element A is made of semi-chemical cellulose, and cotton fiber or a mixture of cotton fiber and semi-chemical cellulose. SINFT filter inserts can reach a very excellent oil filtering function, strong pollution capacity, and strong water absorption.
All this series filter inserts have a filtration accuracy of 3 microns, blocking 98.7% of solid particles larger than 3 microns and about 50% of particles larger than 0.8 microns in one filtration.

CJC Filter Elements Compatible Replacement Products - SINFT Solutions
In the operation of key equipment, the cleanliness and stability of the oil directly affect the efficiency and life of the system. SINFT provides a series of replacement products compatible with CJC filter insert, suitable for industries with high requirements for oil management such as maritime and wind power, helping customers improve maintenance efficiency and operational reliability.
Product models we can provide
SINFT is compatible with the following common models:
A/B/EC/EO/EL/F/MS/DFi/GFi/KFi/PSi and other series of filter elements.
Oil Quality and Pollutant Retention
Several critical parameters directly affect the quality of the oil. Therefore, SINFT's filter elements and filtration systems are designed with consideration for cleanliness levels, total acid number, viscosity stability, foam control capability, and particulate contamination. These factors directly influence the safety of the user's system and maintenance costs.
SINFT provides better cross-reference filter elements for pollutant retention capacity, which comply with the ISO16889 multi-pass test.
Excellent Structural Integrity – Prevents Secondary Contamination
Structural integrity testing:
Our replacement filter elements are tested to 4 microns, 99.9% efficiency and 1000 beta value, ensuring clean oil and extended equipment life. They are highly reliable at 2400 Pa (first pass) and 2700 Pa (group). SINFT replacement filters for CJC have passed rigorous structural integrity testing. The filter media is tightly sealed, with no fiber shedding observed during operation.
Excellent Fluid Compatibility – Ensures System Stability
Compatibility test:
The compatibility test evaluates the water content, viscosity, acid value, and particle level of the oil before and after filtration. The results show that the cleanliness is improved, the water content is reduced, and there is no significant impact on other properties, proving that the oil has good compatibility with the system and our filter element will not cause secondary contamination to the oil.
No Impact on Anti-Foaming Performance – Protects Equipment
Flanders Foam Test:
Our CJC replacement filter elements perform well in the Flender foam test (ISO 12152:2012), with a volume increase of only 12% after 1 minute and 6% after 5 minutes at 25°C, well below the standard limits. Our filters fully comply with the standard and do not remove the original anti-foaming agent in the oil during use.
Note: We have tested the products of three major international oil companies. If you need a complete report, please contact us.
