Introduction
As a leading Chinese manufacturer of string wound filter cartridges, we take pride in delivering high-performance, cost-effective filtration solutions to global clients. Our in-house production facility ensures strict quality control, competitive pricing, and fast delivery—making us the preferred supplier for industries that demand durable, efficient, and customizable filtration.
How String Wound Filter Cartridges Work
String wound filter cartridges utilize depth filtration to capture contaminants throughout the winding layers rather than just on the surface. Made from tightly wound yarn (PP, cotton, or polyester) around a sturdy core, these filters trap particles of varying sizes as liquid flows through. The graded density structure ensures optimal filtration efficiency, from coarse to fine particulate removal.
Why Our String Wound Filters Stand Out
✔ Superior Dirt-Holding Capacity – Deep filtration design extends service life by holding more contaminants before clogging.
✔ Wide Micron Range (1μm–100μm) – Suitable for everything from coarse prefiltration to fine polishing.
✔ Chemical & Thermal Resistance – PP (for harsh chemicals), PET (for high temps), and cotton (for oils).
✔ Low Pressure Drop – Maintains high flow rates with minimal energy consumption.
✔ Reusable & Cost-Efficient – Cleanable via backwashing or ultrasonic methods for extended use.
Robust Construction for Demanding Applications
1. Core: Polypropylene or stainless steel for durability.
2. Filter Media: Choose between PP (chemical resistance), cotton (oil/water), or PET (high heat).
3. End Caps: Melt-bonded PP or metal for leak-proof sealing.
4. Standard Sizes: 2.5"–4.5" diameters; 10"–40" lengths (customizable).
Easy Installation & Maintenance
1. Compatible with standard filter housings (spin-on or bolt-on).
2. Monitor pressure drop to determine replacement timing.
3. Cleanable for reuse in less critical applications.
