String wound filter cartridges resembles the structure of porous outside and dense inside. Using specific technique the fiber yarn is tightly wound on porous core which contributes to good filtration result. It can effectively filter the impurities in the fluid, suspended substances, for instance, rusts, particles etc. Porosity string wound filter cartridge is an up-model products made with current international advanced technology. Advanced winding technique helps to rectify the defects of former products including large resistance and short service life etc. and reduce the utilization cost.

String Wound cartridges provide true depth filtration utilizing hundreds of tapered filtering passages of controlled size together shape. Each layer of roving contributes to true depth filtration by trapping its share of particles. Wound cartridges offer a gradual pressure Increase during cartridge life Versus surface-type media that have an abrupt flow cutoff when loaded. In addition, the Irregular outer layer reduces Surface blinding, assuring both longer cartridge life and full Cartridge utilization.

String wound cartridges covers a wide application area such as Edible Oils, Concentrated Alkalis, Dilute Acids & Alkalis, Mineral Acids, Organic Acids& Solvents, HTF, Oxidizing Agents, Petroleum Oils, Photo Solutions, Potable Liquids, water, Amines, etc.
