BNK filter insert

Specially designed for filtration of insulating oil

CJC® BNK Filter Inserts are based on the technology of the CJC® B Filter Insert type, but are extra dried and vacuum packed, ensuring there is no humidity in the cellulose media. Additionally, the BNK is fitted with a 30 micron strainer in the centre hole for added safety. The BNK is specially designed for insulating oils and it removes all four contamination types in the same process: particles, water, acidity, and varnish. This Filter Insert is used with the CJC® Fine Filters HDU series.

Used for the maintenance of the below oil types and applications: 

  • Tap changer insulating oils
  • Refrigerator compressor lubrication oils

Contamination Capacities:
Based on field experience we have observed that the total Dirt Holding Capacity (DHC) is dependent on shape and density of particles and other variables within an oil system. When saturated, the total weight of accumulated contamination depends on the application, the combination of contaminants, as well as the density of the captured contamination.

Your benefits with CJC®
CJC® Filter Inserts have the highest dirt holding capacity on the market due to special cellulose-based material. Furthermore, the unique construction of the bonded discs, creates a large filtration area resulting in reduced costs of ownership. The CJC® Filter Inserts are a modular design, which allows them to fit any applications and requirements.

  • The CJC® Filter Insert features:
    • Depth media of moulded cellulose
    • Highest Contamination Capacities (DHC)
    • 100% natural cellulose fibres 
  • Removal of contaminants, 4-in-1:
    • Particles:
      Lifetime of both oil and component are increased considerably.
    • Oil degradation products:
      Avoid sticking valves, lacquering, and varnish on metal surfaces.
    • Water:
      Reduce the risk of micro-pitting, bacterial growth, sludge etc.
    • Acidity/TAN:
      Reduce oil ageing and wear on equipment.
  • OEM requirements
    Experience and application knowledge of C.C.JENSEN ensure that CJC® solutions can meet specifications from OEMs on oil cleanliness.
