Automatic Backwash Filter HAWLE-OPTIFIL

The patented HAWLE-OPTIFIL is a fully automatical filter system using the principle of surface-, depth- or cake-filtration. A stainless steel mesh or stainless steel fleece is used as filter material. The particular matter is either separated on the surface or inside the stainless steel mesh or fleece. After reaching a defined level of clogging or time, the automatical backwash process is engaged using only a small amount of the filtered liquid for filter cleaning. Filtration continues without interruption during the unique backwash process. Depending on the type of the filter system (filter area, filter shape) and filtration method (surface-, depth-, or cake-filtration), in relation to the kind of particle (size, agglomeration and shape) the filtration fineness of HAWLE-OPTIFIL starts from 1 μm.
