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.

Notes on Cleaning
Ultrasonic cleaning is recommended rather than back flush cleaning due to its depth and porous filtration media construction.
