Self-Cleaning Backwash Filter Screen Element is selected when an assembly or process calls for filtering water and process liquids continuously in automatic self-cleaning filters, where a sintered-mesh or wedge-wire cylinder is back-washed by a suction scanner without stopping flow. This application guide to the Custom to filter housing type covers concrete end-uses, the specification checklist, correct installation, and where an alternative mesh or filter medium performs better.
