Fine Filter Inserts from CJC®: your depth filters for the highest oil and fluid cleanliness
Feinfilter inserts — depth filter and cellulose
Fine filter cartridges specially designed for our oil and fluid care systems that are highly efficient in removing all contaminants from oils and fluids — particles, water, oil aging products (oxidation residues, varnish, oil sludge) and acids. Filtermaterial made of 100% natural fibres. Thanks to the unique combination of filter material and type of filtration, our fine filter inserts offer an extraordinarily high dirt holding capacity and absolute filtration. Heat-resistant, acid-resistant and robust, the natural fibers are also ideally suited 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.

Product features — CJC® Fine Filter Inserts
We have developed and optimized the filter material and design of each CJC® Fine Filter Insert specially for its particular application area. For the extraction of the filter material, we search for and combine the suitable cellulose and cotton fibers in special selection processes.
Heat-resistant, acid-resistant and absolutely 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 a high tendency to acidify, e. g. gas engine oils and phosphoric acid esters
- Oils and fluids with high water content that has to be minimized in short time, 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 fibers offers an additional inner surface of 120 to 150 m² per gram in addition to the outer surface. This results 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 fibers. 75% of the insert volume forms a cavity structure.
Water
Via capillary attraction all three stages of water – free, emulsified and dissolved water – is absorbed by the cellulose fibers. This function can be deactivated for aqueous fluids.
Oil degradation products
Oxidation residues, varnish, resins and sludge-like degradation products deposit permanently on the cellulose fibers 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 / recept that is 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.
CJC® Fine Filter Inserts constist 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.

That say our customers
“I am completely satisfied with the investment. Oil drying takes place very quickly and without system downtime. In this way, we maintain production, have time to look for the fault, save ourselves the oil change and disposal and maintain the oil quality.”
„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 […].“
“I am pleasantly surprised how quickly the oil was cleaned. The service life of the in-tank filter has been extended significantly, and the maintenance effort has been reduced obviously. The result is so convincing that we decided to purchase a CJC® offline filter for the forge as well.”
“It is remarkable how clean the oil has become. We have already tried several filters, but only with the filters from CJC®, we did achieve the desired oil purity. In the meantime, we have already retrofitted four systems in our production with CJC® offline filters.“
„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.“
„Since the CJC® filter was put into operation, the service life of the oil has multiplied. The oil remains as clear as fresh oil despite the heavy dirt load. We visibly have less abrasion on the components. The CJC® filter is a simple but very effective measure to reduce wear and thus maintenance efford.“
„We are very satisfied with the CJC® offline filter. The filter insert has to be replaced only once per year.”
„The high quality of the die-cast parts relies on well-functioning production plants, which can be achieved only with proactive maintenance and, among other things, an absolutely clean operating medium (HFC fluid).“
„We were so convinced by the results that we equipped another drop forging hammer with a CJC® offline filter CJC®.“
“Our experiences with operation and filter replacement are excellent! We have weight the used filter insert. 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 :)!
“The comprehensive oil analyses of OELCHECK convinced us. They clearly show the continuous improvement of the oil quality – further gearboxes will be retrofitted with CJC® filters.”
“Having undertaken an assessment of our onsite lubrication activities, we introduced a program of offline filter installations as a 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.”
“Within just two hours, the oil in the gearboxes could be cleaned to such an cleanliness level that it was comparable to fresh oil.”
„The perfect solution to help our oil-consumption-ratio concerns, now we can save on oil change and can increase our machine reliability.”
„With the use of the CJC® offline filters, the oil quality has improved to such an extent that the annual oil change is eliminated and valves are spared.”
„ “The CJC® offline filters were installed because it is only possible to work continuously with clean oil due to the fine filtration, which is essential for the proper operation of all valves and components. It is also noteworthy that the oil service life and the oil change intervals have been extended. So we also achieved economic savings: reducing the waste oil amount and thus protecting the environment.“
„The reason for installing the CJC® offline filter system was not only the avoidance of failures and improved maintenance of the machines but also all the high savings in oil costs and the associated reduction in the amount of waste oil – — an advantage for the environment. Due to the filtration with CJC®, we can use the oil in the hydraulic system for up to 4 years.”
„Since the start-up of all twelve plastic injection moulders machine-manufacturer-equipped with CJC® off-line filters, no breakdowns of hydraulic systems of any of the machines have been noted. At the same time, we have observed a prolonged lifetime of pumps and proportional valves.”
„Installing the CJC® offline filters is by far the best preventive maintenance measure we have ever undertaken […] We had no unforeseen failures due to resins or other contaminants in the valves. Cleaning the hydraulic tanks was also not necessary.”
„Before the installation of the CJC® Filters in all our injection moulders, we had to change the oil and the in-line filters very often, and still the system remained contaminated. We spent a lot of hours on maintenance of every engine because of the contamination, which we at that time did not think was so important. A short while after installation of the CJC® Filters, we noticed a reduction in the stoppages as the oil no longer was contaminated by particles, resins and water. It has been one of the best maintenance investments until today.“
„We are very satisfied with the results after installing CJC® Fine Filters on our hydraulic presses, and all new machines are immediately equipped with CJC® Fine Filters.“
„Thanks to the CJC® offline fine filters, the automatic lathe now works much more efficiently. The number of system failures and the associated costs have been reduced. Filtration with CJC® is invaluable, even though we only use 60 litres of oil.“
„Karberg und Hennemann has kept its promise regarding the performance of the CJC® filter system. Through the multiple uses of our hydraulic oil, we significantly reduced running costs and expenses as well as storage volumes and the associated environmental risks.“
“We were convinced of the result in a short time and can only recommend the CJC® offline filter 27/27 with the CJC® fine filter insert B to prevent wear at an early stage.”
“I no longer have any problems with dirt in the valves. The lifetime of the hydraulic pump and motor will undoubtedly be extended now that we are using the CJC® fine filter. The results from the oil analyses are excellent.”
“The hydraulic servo valves are no longer failing due to contaminants in the oil. We have made huge savings on the components and labour along with mill downtime relating to the servo valves on the bandsaw log carriage.”
„Since the installation of the CJC® Offline Filter we have never had to clean or to do maintenance on the valves.“
„After knowing CJC® Filters and having installed them on our injection machines, we have got the suitable oil quality and reduction of yearly unplanned stoppages from 18 to 2 times. At present we are certain to work with oil in very good conditions and suitable at all times for our facilities. The investment to install CJC® Filters was a right decision and a pro-assets good maintenance tool.“
“Because we are satisfied with the performance of CJC® Off-line Filtration, we are considering the purchase of additional CJC® Off-line Oil Filtration units.”
