Stainless steel sintered fiber web is a kind of multipore deep filter media, sintered with stainless steel fiber at the high temperature. The filter elements enjoy the advantage of high porosity, large filter area and good dirt holding capacity, and can also be used repeatly after chemical cleaning, etc.
