The filter has thus a dynamic influence on the NPSH-value of the plant. To take this effect low a filter have to show a low drag coefficient and a large filter surface. For a uninterruptible operation a double filter installation is require, whereby the same maxim applies here with regard to the resistance coefficient for the switch valve. Especially for large flow rates, the switch-over unit is a constructional challenge regarding the filter size and the required positioning forces for the manual switching.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile\" style=\"grid-template-columns:36% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"273\" height=\"249\" src=\"https:\/\/industrial.filtrationgroup.com\/wp-content\/uploads\/2019\/10\/Bild7_1.png\" alt=\"\" class=\"wp-image-1395\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p><strong>Technical Data<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Nominal size DN 350<\/li><li>Filter surface: 18.690 cm\u00b2<\/li><li>Filter fineness: 800\u03bcm<\/li><\/ul>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile\" style=\"grid-template-columns:36% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"273\" height=\"249\" src=\"https:\/\/industrial.filtrationgroup.com\/wp-content\/uploads\/2019\/10\/Bild10.png\" alt=\"\" class=\"wp-image-1397\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p><strong>Solution<\/strong><\/p>\n\n\n\n<p>The valve-Duplexfilter series VS87 is in welded designed.
