PSSF Stainless Steel Pleated Felt
Filter Cartridge

Cobetter PSSF Stainless Steel Pleated Felt Filter Cartridges are composed of stainless steel sintered felt shaped during the pleating process.  These filters have a large filtration area with high flow rates and low pressure drops. The unique  stainless steel sintered felt is made from stainless steel fibers which have been sintered to form a high 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 with excellent filtration efficiency and longer service life.  These filters are widely used in steam filtration or liquids with high viscosities, e.g. sugars and syrups.
