Cobetter PSSF Stainless Steel Pleated Felt Filter Cartridges constructed with stainless steel sintered felt and shaped during the pleating process. These filters have a large filtration area.
The stainless steel sintered felt is made from stainless steel fiber, which is then sintered under high temperatures to form the porous depth filtration material.
PSSF Filter Cartridges features include a graded pore size from coarse upstream to fine downstream, which results in a higher dirt holding capacity and longer service life.
PSSF II is made of “Bekaert” stainless steel felt and achieves close to absolute retention efficiency.
