EO Filter Inserts

Specially designed for neutralization of acidic oil degradation products 

CJC® EO Filter Inserts are made for elimination of oil degradation products, reducing varnish and acidity and increasing the resistivity of the oil. EO Filter Inserts contain alumin­ium oxide filter media. Its large surface area enables enhanced neutralization of oil contaminants such as acidic oil degradation and oxidation by-products, resins, sludge, and varnish. EO Filter Inserts may be used to remove varnish and acidic oil degradation products from high temperature oil and thus reduce the TAN and MPC values. 

The EO Filter Inserts must be used in combination with CJC® cellulose Filter Inserts as post filters, either in the last stage of a CJC® HDU multi stay Filter or in a CJC® HDU single stay Filter using hybrid Filter Inserts. 

Applicable in the following oils:

  • Mineral oil
  • Hydraulic fire resistant fluids (HFD) 
  • Glycol oil - Polyalkylene glycols (PAG) 
  • Ester oil - Polyolester oil (POE), Phosphate Ester oil, Environmentally acceptable Lubricants (EAL) and biodegradable oils

Used in the following applications:

  • Transformer insulation
  • Gear and bearing lubrication
  • Hydraulic systems 
  • Compressor lubrication
  • Turbine lubrication 
  • Engine lubri­cation 

User benefits:

  • Reduction of TAN and MPC, Increase of Resistivity 
    CJC® EO Filter Inserts neutralize acidic oil degradation products and varnish, lower MPC and TAN and increase the Resistivity of the oil. 
  • Prolonging the oil life time and avoiding oil change
    CJC® EO Filter Inserts eliminate oil contami­nants and oxidation catalysts , restore and maintain the oil in good condition.
  • Preventing failures and mitigating risk of downtime 
    Clean oil ensures reduced wear, extended component lifetime and lower O&M costs
