The new filter combination of BKG® screen changer from Nordson is able to withstand the squeezing pressure, providing maximum filtration and optimum melt flow; Compared with the low-end filter on the market, the service life is longer and more reliable.　 　　A key factor in enhancing the performance of the new filter combination is the powerful multi-layer structure that prevents the pressure differential (up to 200 bar) encountered during filtration from causing failure.
　　Nordson precisely adjusts the size of the filter combination to the cavity size, eliminating the common problem of contaminants passing through the filter combination at the edges. In addition, during the production process, all filter components are ultrasonically pre-cleaned to eliminate contamination from oil and grease used in the weaving process.
