Depth filters made of phenolic-resin with acrylic fibers


The ProBond Depth filter cartridge with a nominal filtration rate has a two-stage construction. An outer, spiral-form filter-layer, serves as a pre-filter. The inner, finer filter layer define the actual filter ration. Due to the use of long, phenolic-resin impregnated acrylic fibers the ProBond possesses a stable filter structure and permits construction without a core support. ProBond Depth filter cartridges contain no silicon and are therefore especially suited for simple filtration uses or pre-filter applications of paints and varnishes. The two-stage construction as well as the depth filter configuration guarantees a long service life, high dirt-retention capacity and low differential pressure.
