filter insert BNK 15/25
The BNK 15/25 Filter Insert is manufactured especially for CJC® Oil Filters for filtration of
- insulating oils in tap changers
- refrigerator compressor lube oil
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.
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 2 litres of evenly distributed solids.
Oxidation by-products, resin / sludge, and varnish are retained by the cellulose material. The cellulose will retain appr. 1 kg of degradation products.
The water absorption potential is up to 55% (i.e., 750 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!
