WFV Filter Fleece Rolls
WFV Filter Fleece Rolls for Belt Filter Systems
There are four different filter fleece types available for optimum matching to the solids to be separated as well as to the existing liquid system. Filter fleeces for surface filtration are FDU, which is produced in a melt fibre process from PP and PET, and FLI, which is produced in a chemical binding process from viscose.
Filter fleeces for depth filtration are the FLO, produced from PET in a thermal binding process, and the likewise thermally bonded, but additionally needled FKI made from viscose/PET fibre blend.
FDU, FLI, FLO and FKI are available in each case in different grades, which can be differentiated according to weight in gr/m. All filter fleeces are rolled up into rolls. Usual roll widths are between 500 mm and 1300 mm. The standard length of the filter fleeces per roll range from 50 m up to 200 m. Special widths and lengths can be supplied on request.
