Care your oil instead of just filtering it — for the maximum service life of oil, components and machine
CJC® Offline Filters: Your solution for absolutely clean and dry oils and fluids


Offline Filters
CJC® Offline Filters clean, dry and maintain the oil or fluid in your machines quickly and cost-effectively. Whether hydraulics, gearboxes or thermal oil systems, whether mineral or synthetic base oils and whether how heavily loaded, the offline filter from CJC® is precisely configurable to the specific conditions of your machine and the impurities in your oil or fluid. Installed in the offline circuit, it ensures maximum oil cleanliness regardless of the operation of the machine. The filter removes solid particles, water, oxidation residues and acids effortlessly and permanently.
How you benefit from installing a CJC® Offline Filters on your machine
Maximum oil and fluid cleanliness is the be-all and end-all for reliably functioning machines and resource-saving maintenance. It’s that easy — watch our videos:

Product Advantages — CJC® Offline Filters
Customized solutions
Perfectly adaptable to any machine and any oil or fluid. The CJC® Offline Filter is individually configurable, thanks to its modular design. Optionally with customer-specific sensors for integration into your condition monitoring system.
Maximum oil cleanliness
Highest oil purity and maximum wear protection. The CJC® Offline Filter removes all contaminants – regardless of operation, continuously and highly efficiently. For maximum service life of oil and components.
Economical & ecological
Depth filter made of 100% natural fibers — 0% plastic and 0% metals. High recording capacities and thus long filter life ensure the excellent price-performance ratio of the CJC® Offline Filters.
Easy installation & maintenance
Easy to install as an offline filter in an independent circuit. This also means changing filters without machine downtime. Low-maintenance, robust and durable, the CJC® Offline Filters also convince.
Areas of application — CJC® Offline Filters
Modular design — CJC® Offline Filters
The integrated CJC® Depth Filter Inserts
Separation capacity:
- Solid particles (wear and impurities)
- Water – free and dissolved
- Oil degradation products and oxidation residues (Varnish, oil sludge)
- Acids
Type of filtration:
- Depth filter with extremely high recording capacity
Inner surface:
- 120—150 m² per gram
- The largest depth filter insert has an internal surface of > 2,066 ha = > 2,894 football fields
- The smallest depth filter insert has an inner surface of > 5 ha = > 7 football fields
Due to the modular design, the number of various depth filter inserts and thus the holding capacity can be adapted to the individual dirt input.
Volume:
- The largest depth filter insert has a volume of > 504 Litres
- The smallest depth filter insert has a volume of > 1.5 Litres
Filtration degree:
- 3 µm absolute, retention rate down to 1 µm (Micrometer)
Filter material:
- 100% natural fibres – meets the requirements of the Circular Economy Act
For oils and fluids that tend to acidify very quickly, an additional filter material may be used, which increases neutralization against acids many times over.
Customer cases
Find out in our application studies how operators benefit from installing a CJC® Offline Filter.
“I am completely satisfied with the investment. Oil drying takes place very quickly and without machine downtime. Thus, improves the productivity, allow us to have time to look for the failure cause, to avoid the oil change and waste oil disposal and to maintain the oil quality.”
Read customer case
“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.”
Read customer case
“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.“

„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).“
Read customer case
“We were so convinced by the results that we equipped another drop forging hammer with a CJC offline filter.”
„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.“
Read customer case
“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.”
Read customer case
„We are very satisfied with the CJC offline filter. The filter insert has to be replaced only once per year.”
“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.”
Read customer case
“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 above 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 offline 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 did not think was so important at that time. A short while after installing 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.”

“After knowing CJC Filters and having installed them on our injection machines, we have got the suitable oil quality and reduced of yearly unplanned stoppages from 18 to 2 times. We are currently certain to work with oil in very good conditions and are suitable at all times for our facilities. The investment to install CJC Filters was a right decision and a pro-assets good maintenance tool.”
