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 features — CJC® Fine Filter Inserts

depth filter, fine filter inserts, depth filter insert

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.

depth filter, filter capacity

Surface filters retain contaminants only on the surface and offer a comparatively low filter capacity despite folding. Frequent filter changes are the result:

surface filter, in-line filter

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.

„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 […].“
