Petroleum filter cartridge SWG series

oilfinepolypropylene

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. The non-woven fabric is pressed into the bottom of the filter element and prevents trapped contaminants from re-entering the system. Type SWG Type SWG (water-glycol) is designed for filtration and treatment of water-glycol based industrial liquids. The WG filter element is made completely of polypropylene (PP). The filter element removes solid particles from a size of 10µm. The filter element is designed to remove solid particles to purity class NAS1638 8-9, ISO4406 19/17/14. The SWG filter element is designed for the treatment of industrial fluids in low pressure systems.
