filter insert BNK 27/27

 
The BNK 27/27 Filter Insert is manufactured especially for CJC™ Oil Filters for filtration of

  • insulating oils in tap changers

for efficient particle and water removal. 

The BNK Insert is dried especially for optimal water and dirt-holding capacity.
The Filter Insert is mounted with a strainer in the centre hole.  

Filtration capability

Particle removal
All CJC™ Filter Inserts have an oil filtration degree of 3 µm (micron) absolute. This means that 98.7% of all solid particles larger than 3 µm and approximately 50% of all particles larger than 0.8 µm are retained in one pass. The dirt-holding capacity of a BNK 27/27 Insert is 4 litres of evenly distributed solids.

Degradation products
Oxidation by-products, resin / sludge, and varnish are retained by the cellulose material. The cellulose will retain appr. 4 kg of degradation products.

Water removal
The water absorption potential is up to 50% (i.e., 2200 ml H20) of the total contaminant holding capacity.

How do you ensure clean & dry oil

Remember to change CJC™ Filter Inserts according to pressure gauge or at least once a year in order to ensure clean & dry oil!
