Introduction
As a leading Chinese manufacturer of high-quality string wound filter cartridges, we specialize in producing precision-engineered filtration solutions for industries worldwide. Our in-house manufacturing ensures strict quality control, competitive pricing, and reliable performance. If you're looking for durable, efficient, and cost-effective filtration, our string wound cartridges are the perfect solution.
How Does a String Wound Filter Cartridge Work?
String wound filter cartridges operate through depth filtration, where contaminants are trapped throughout the entire winding structure—not just on the surface. The filter media consists of cotton, polypropylene (PP), or polyester (PET) yarn tightly wound around a core in multiple layers. As fluid passes through, particles are captured within the fibrous matrix, ensuring high dirt-holding capacity and extended service life.
Key Features of Our String Wound Filter Cartridges
✔ High Dirt-Holding Capacity – The dense winding structure traps large volumes of contaminants without frequent clogging.
✔ Multiple Filtration Grades – Available in 1μm to 100μm to suit different purification needs.
✔ Chemical & Temperature Resistance – PP and PET options withstand acids, alkalis, and high temperatures.
✔ Low Pressure Drop – Optimized flow rate reduces energy consumption.
✔ Cost-Effective & Reusable – Cleanable and long-lasting for economical operation.
Easy to Use & Maintain
Installation: Compatible with standard filter housings (spin-on or bolt-on).
Cleaning: Backwashing or ultrasonic cleaning can extend lifespan.
Replacement Indicators: Monitor pressure drop to determine when to replace.
