Polypropylene String Wound Filter

 

Polypropylene string wound filters deliver robust depth filtration for challenging liquids. Engineered with continuous polypropylene filament wound around a corrosion-resistant core, these cartridges efficiently capture particulate contaminants while maintaining high flow rates. Ideal for pre-filtration, chemical processing, and protecting downstream equipment.

✅ Depth-Filtration Efficiency

Multi-layer winding provides high dirt-holding capacity and graded porosity, reducing filter change-outs.

✅ Chemical & Thermal Resistance

Up to 82 °C continuous operating temperature; compatible with acids, alkalis, and solvents.

✅ Precision Filtration

Available from 1–100 μm with strict pore size tolerance (±3%).

✅ Zero Fiber Shedding

Continuous filament construction eliminates media migration.

✅ Customizable Configurations

Available in various lengths, diameters to suit OEM and retrofit needs.
