Sustainability begins with the filter! Our filter material consists of 100 % natural fibres.
Fine filter inserts from CJC®: your depth filters for the highest oil and fluid cleanliness
Fine filter inserts — depth filters and cellulose filters
Fine filter inserts specially designed for our oil and fluid care systems are highly efficient in removing all contaminants from oils and fluids — particles, water, oil ageing products (oxidation residues, varnish, oil sludge) and acids. Made of 100% natural fibres. Due to the unique combination of filter material and filtration type, our fine filter inserts offer an exceptionally high dirt holding capacity and absolute filtration degree. Heat-resistant, acid-resistant and robust, the natural fibers are also ideally applicable for demanding filtration cases. We continuously develop our filter material to achieve the best result: highest oil and fluid cleanliness — efficient and cost-optimal for every application.
How you benefit from CJC® Fine Filter Inserts
You optimally protect your oils and fluids – remove all contaminants and slow down oil ageing
You ensure maximum wear protection and preserve the expensive in-line filters
Because of the high filter capacities, you benefit from an excellent price-performance ratio
For filter insert replacement of our fine filter inserts you don’t have to take the machine out of operation
Fewer oil changes, fewer failures, lower costs and at the same time, resource-saving maintenance
Product advantages — CJC® Fine Filter Inserts
4-in-1 solution
Our fine filter inserts remove particles, water, oil ageing products and acids.
100 % natural fibres
The filter material made from sustainable raw materials preserves resources and the environment — 0 % metals, 0 % chemicals.
Depth filter
Our fine filter inserts are solids that provide an internal surface area of 120-150 m² per gram.
Filter efficiency
The filtration degree of each fine filter insert is 3 μm absolute with a retention rate of up to < 1 μm (submicron range).

Product features — CJC® Fine Filter Inserts
We have developed and optimised the filter material and design of each CJC® Fine Filter Insert, especially for its particular application area. For the extraction of the filter material, we search for and combine the suitable cellulose and cotton fibres in individual selection processes.
Heat-resistant, acid-resistant and robust, the cellulose filters are ideal for:
- Mineral oils and synthetic lubricants up to ISO VG 460 / 40 °C, including biodegradable fluids
- water-containing oils and fluids, e. g. water-glycol and cooling lubricants
- Oils and fluids with extremely high dirt ingress and thermal stress, e. g quenching and thermal oils.
- Oils and fluids with an increased tendency to acidify, e. g. gas engine oils and phosphoric acid esters
- Oils and fluids with a high water content that has to be minimised quickly, e. g. insulating oils
CJC® Fine Filter Inserts are depth filters, i. e. contaminants are retained in the depth of the filter material. The whole volume of the insert made of finely ramified fibres offers an inner surface of 120 to 150 m² per gram in addition to the outer surface. The huge surface and volume result in an enormously high filter capacity. The higher the capacity, the longer the filter lifetime. How much dirt a CJC® Fine Filter Insert can ultimately absorb depends on the type of contaminants.
Surface filters retain contaminants only on the surface and offer a comparatively low filter capacity despite folding. Frequent filter changes are the result:
Particle
Solid particles are permanently retained between the cellulose fibres. 75% of the insert volume forms a cavity structure.
Water
Via capillary attraction, the cellulose fibres absorb all three stages of water (free, emulsified and dissolved water).
For aqueous fluids, we use filter inserts that don’t absorb water.
Oil degradation products
Oxidation residues, varnish, resins and sludge-like degradation products deposit permanently on the cellulose fibres with a combination of adsorption and absorption.
Acids
Inorganic acids (nitric acid, sulfuric acid, etc.) dissolved in the water are absorbed by the cellulose with the water. The generation of organic acids is prevented by minimising oil ageing products (precursors).
Field tests from practice confirm that we achieve and maintain the oil cleanliness levels recommended by manufacturers for the most sensitive components.
All CJC® Fine Filter Inserts have a filtration degree of 3 µm absolute with a retention rate of 1 µm nominal and smaller (submicron range). That means, that > 98.7 % of all solid particles > 3 µm and > 50 % of all solid particles > 1 µm in are retained in one filter pass.
The filtration efficiency of the CJC® Fine Filter Inserts in the submicron range depends on the particular formulation meaning the used fibres. So special insert types achieve a filtration efficiency of > 10% for solid particles >0.1 µm.
CJC® Fine Filter Inserts are particularly efficient because they ensure a long contact time between fluid and filter material.
The machine remains in operation for the filter insert replacement because the CJC® Oil Care System operates independently in a separate circuit.
CJC® Fine Filter Inserts consist of 100 % natural fibres made of sustainable resources. They thus comply with the objectives of DIN EN ISO 14001 “environmental management systems” and the circular economy. In Germany, you can dispose of CJC® Fine Filter Inserts according to the waste key 150202 — 0% metals and 0% chemicals.
CJC® Fine Filter Inserts
Whether hydraulic, lubricating or gear oil, turbine or compressor oil or extreme cases such as thermal oil, quenching oil, cooling lubricant or gas engine oil — CJC® Fine Filter Inserts ensure the highest oil and fluid cleanliness. Sensationally high dirt holding capacities and excellent separation performance make our inserts efficient and cost-optimal.

„The CJC lube oil filter […] is a reliable and efficient alternative […]. […] engine lube oil properties were maintained in specified areas (viscosity, additives, TBN, particle and water content) or improved (e. g. dispersancy). The high savings potential regarding lube oil losses, energy costs and CO2 emissions are convincing […].“

„We are convinced […]. The oil is clean and clear […] otherwise there would have been huge damage of several thousand euros with enormous downtimes and production losses. […] impressed […], that the fine filtration of the oil has such an extreme impact on wear pattern. […] remaining five crushers were also equipped with CJC offline filters.“

“Our experiences with operation and filter replacement are excellent! We have weight the used filter insert. The drained net weight among 49.2 kg – i. e. in total, the CJC oil filter >removed 38 kg dirt. The engine lube oil on the test membrane is brown and not black anymore! The CJC oil filter is really efficient :)!”

“Having undertaken an assessment of our onsite lubrication activities we introduced a program of offline filter installations as proactive maintenance strategy across the site. This has allowed us to move from a situation where oil replacements were frequent to nearly no oil changes at all. CJC oil filters have been a huge help in this program.”
