BNK 27/27 Filter Inserts are manufactured especially for CJC® Filters for oil filtration of
- insulating oils in tap changers
for efficient particle and water removal.
BNK Inserts are dried especially for optimal water and dirt-holding capacity.
The 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 4 litres of evenly distributed solids.
Oxidation by-products, resin / sludge, and varnish are retained by the cellulose material. The cellulose will retain appr. 4 kg of degradation products.
The water absorption potential is up to 50% (i.e., 2200 ml H20) of the total contaminant holding capacity.
