Cotton String Wound Cartridge (FDA)

Bleached cotton string wound cartridges provide economical depth filtration with excellent dirt-holding capacity and low pressure drop. FDA-grade cotton yarn is precision wound over a rigid polypropylene core to form a gradient-density structure that captures particles throughout the media thickness. This 2.5" OD DOE (double open end) design fits most standard industrial and sanitary housings.
