Petroleum filter cartridge TRAFO series

condensateoilfine

The filter cartridge is the most important element of the filter system. Filter elements with one process remove solid impurities + water + soft sludge (sediments, resins, varnishes). Filter elements are made according to the type of treated liquid. For industrial liquids based on petroleum products, the filter elements are made of special cellulose produced according to a special recipe. The cellulose is wound onto the core on computer-controlled winding machines. The cellulose coil, which ensures the precise capture of contaminants, is adapted specifically for individual types of filter inserts. The lower part of the filter insert is pressed into a reinforcing paper circle so that it has a higher density than the upper part. This design guarantees gradual capture of contaminants. Larger contaminants are captured in the upper part and smaller ones up to 1 µm in the lower part of the filter insert. The hard paper circle increases the accuracy of filtration and prevents deformation of the filter elements. Type TRAFO is designed for filtration and treatment of insulating (transformer) oils. The filter element removes and traps free and bound water and solid particles from 1 µm in size. The filter element is designed to remove free and bound water to a level of 1 ppm (1gm/litre) and solid particles to NAS1638 cleanliness class 3, ISO4406 14/12/9. After treatment with the TRAFO liner, the insulating oil achieves a breakdown voltage ≥ 70 kV/2.5mm. The TRAFO filter element is designed for the treatment of oils in electrical systems with insulating oils.
