Products Description
Wound cartridge, also called string wound filter cartridge. It is usually designed with continuous filaments (usually polypropylene, cotton or glass fiber) wound under precise tension onto a core material, providing excellent depth filtration for liquids and gases.
Ideal for pre-filtration, our wound cartridges can effectively remove particles such as sediment, rust, sludge and scale at various micron levels, protecting downstream equipment and ensuring process fluid purity.

features
1️⃣ Maximized Contaminant Loading
Deep bed filtration captures significantly more particulate than surface filters, extending service life and reducing change-out frequency.
2️⃣ Exceptional Flow-to-Dirt-Holding Ratio
Optimized winding density ensures high flow rates while maintaining outstanding particle retention efficiency.
3️⃣ Broad Chemical Compatibility
Available in multiple yarn materials to withstand aggressive chemicals, solvents, fuels, and high temperatures.
4️⃣ Rigorous Structural Integrity
Precision winding on durable cores prevents media migration and withstands high differential pressures without collapse.
5️⃣ Tailored Performance
Customizable micron ratings, lengths, and end caps for exact application fit.
Testing Capabilities
- Integrity Testing: Bubble-point and diffusion‑flow tests to verify microfiber integrity and confirm pore-size performance.
- Flow & Differential Pressure: Performance validation under simulated operating conditions to certify ΔP and flow‑rate specifications.
- Material Analysis: FTIR and DSC analysis for polymer verification and thermal stability assessment.
- Contaminant Challenge: Standardized particulate-loading tests per ISO 9001 protocols to determine real‑world service life and capture efficiency.
