String Wound Cotton Depth Filter Cartridges

String Wound Cotton Depth Filter Cartridges

CECO Sethco String Wound Cotton Depth Filter Cartridges are fabricated of natural or synthetic fiber wound over a perforated plastic or metal core. The precision winding pattern covers the entire depth of the filter tube with hundreds of funnel shaped tunnels which become gradually finer from the outer surface to the center of the tube and trap progressively finer particles as the fluid travels to the center. This allows much greater solids retention capacity than is associated with surface filter media of the same dimensions.


CECO Sethco provides top-quality pumps and filter cartridges for use in a number of applications. When dealing with corrosive and hazardous chemicals in a variety of industries, experts trust Sethco filter cartridges to be reliable and efficient as soon as they are installed. Sethco sets the industry standard when it comes to dependability.

Sethco products have an excellent reputation. If you need to filter acids, alkalis, or any other hazardous liquids, our cartridge filters will handle the job. The precision winding patterns of our String Wound Cotton Depth Filter Cartridges trap progressively finer particles as the fluids transverse toward the center of the cartridge. Businesses all over the world trust Sethco cartridge filters.
