Products Description
Crafted for demanding industrial liquid filtration, our string wound water filters utilize continuous filaments of high-purity polypropylene (PP) , glass fiber or cotton yarn meticulously wound around a robust core. This precise depth filtration construction effectively traps suspended solids, rust, and sediment across a wide particle size range, delivering consistent clarity and protecting downstream equipment.
