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

  • You achieve a maximum service life for your oils and fluids – so you protect budget and resources at the same time.

  • They ensure maximum wear protection and reduce maintenance effort and costs.

  • You minimize failures and ensure maximum reliability and availability of your machine(s).

  • You optimize productivity and processes and accelerate the return on investment.

  • You protect the cost-intensive inline filters, so they clog less frequently and require fewer filter changes.

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:

Technical Manager, Managing Director, Kröger Stahlumformung GmbH

„ “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.“

Maintenance management, AZULIBER 1, S.L.

„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.”

Read field report – Injection moulding machine

Maintenance Manager, One of the largest plastic injection moulding companies in Europe

„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.“
