Applications
Wound string filter cartridge is a depth filter made by continuous winding of yarn (cotton, polypropylene, or polyester) around a central core. The winding pattern creates a graded density structure that captures particles throughout the depth of the cartridge. Ideal for sediment removal, water pre-filtration, and industrial process filtration where high dirt holding capacity is required.
Key Features
- Graded Density Winding -- Tight outer, loose inner for deep filtration
- Multiple Yarn Options -- Cotton, PP, or polyester fiber
- High Strength Core -- PP or SS304 center tube options
- Excellent Chemical Resistance -- Compatible with acids, alkalis, solvents
- High Flow Rates -- Low pressure drop across operating range
- Economical Choice -- Cost-effective for high-volume sediment removal
