String Wound Filter Cartridge
The string wound filter cartridge is a depth filter made by winding filter yarn around a support core. It provides high dirt-holding capacity for sediment, rust, scale, and suspended solids in water treatment, oil filtration, chemical processing, plating, coatings, and general industrial liquid systems.

Flow rates are guidelines at 1 bar differential pressure with water at 20 C. Actual capacity varies with viscosity, micron rating, and particle load.
How It Is Built
Wound depth filtration structure
The yarn winding pattern creates a depth filter path that captures particles throughout the cartridge body and supports high dirt-holding capacity.
Media and core matching
Yarn material and core material can be selected according to liquid chemistry, temperature, pressure, and mechanical strength requirements.
