The SP/SE/SG series string wound filters are engineered to meet the toughest industrial demands. By carefully winding textile fibers around a central core, SP/SE/SG series string wound filters achieve a gradient density structure, delivering exceptional performance in capturing sediment, rust, and scale.
We provide a thoughtfully curated range of core materials (SS304/PP) and filter media options (Bleached Cotton/Glass Fiber/PP) to ensure optimal chemical compatibility and thermal stability for a wide variety of fluids.
Differentiated Material Combinations & Fluid Compatibility
In the string wound filters, the effectiveness of your filtration process hinges on the precise pairing of filter media (yarn) and the support core. Our offerings include expertly designed combinations tailored to meet the demands of intricate industrial applications.
| Combination Strategy | Yarn Material | Support Core | Compatible Fluids & Applications |
| Standard Economic | Polypropylene (PP) | PP | Potable water, acids/alkalis, plating solutions, DI water pre-filtration. Best for temperatures below 60°C. |
| Industrial Heat-Resistant | Bleached Cotton | SS304/316 | Lubricants, organic solvents, edible oils, fine chemicals. High temperature resistance up to 120°C; Silicone-free. |
| Extreme Conditions | Glass Fiber (GF) | SS304/316 | Hot thermal oils, aggressive acids, high-temp steam condensate recovery. Extreme temp resistance up to 400°C. |
| Chemical Stability | Polyester | SS304 | Chemical intermediates, aromatic hydrocarbon solvents; offers superior oxidation resistance compared to PP. |
Our Advantage in the Market:
Reinforced SS304/316 Cores: We employ spiral-welded stainless steel cores for high-viscosity fluids (resins, concentrates) because they can bear differential pressures of up to 0.4 MPa without deforming, hence eliminating "bypass leakage."
Low-Migration Tech: To greatly minimize fiber shedding and guarantee the purity of the downstream filtrate, our cotton and glass fiber yarns go through a sophisticated scouring procedure.
Product Advantages
The drawbacks of conventional filter bags, like clogging, ineffective filtering, and subpar cleaning results, are overcome by the Kangxun fiberglass dust filter.
Achieve "ultra-low emissions" and "surface filtration" simultaneously.
Assist businesses in cutting emissions, energy use, and operating expenses.
Optimized Structure:
High-temperature and corrosion-resistant low-adhesion polymer material + high-strength support.
High Efficiency & Low Resistance:

About us
Laboratory Equipment & Testing
thorough testing of final products, careful management during production, and strict raw material selection.
SP/SE/SG series string wound filters are made of high-quality textile fiber roving materials. Through advanced gradient winding technology, a filter layer with gradually denser pores is formed from the outside to the inside. It is tightly wound on a high-strength porous skeleton and uses overall one-time molding technology to ensure structural stability. This series of filter elements has unique deep filtration characteristics and can effectively intercept various impurities such as suspended particles, rust, and sediment in the liquid. The filtration accuracy can reach 1-100 microns. Its special wire wound structure design ensures a large pollutant holding capacity while maintaining a low filtration pressure difference.
SP/SE/SG series string wound filters are particularly suitable for treating liquids with low viscosity (such as water, solvents, etc.) and low impurity content. SP/SE/SG series string wound filters are widely used in pre-filtration and security filtration in the fields of electronic ultrapure water, food and beverage, pharmaceutical technology, etc., and are ideal for liquid purification.
