String Wound Filter Cartridges (AquaFil)

Vens AquaFil cartridges are made by winding polypropylene or absorbent cotton yarn on a central core. The winding density sets the retention rating, so one construction covers coarse and fine duties. They filter through their full depth and remove suspended solids, particles and rust.
