Wound Filter Cartridges
Wound Filter Cartridges
Overview: String wound filter cartridges are designed to provide efficient filtration by utilizing a gradient density construction. They are made from various materials such as polypropylene, bleached cotton, or glass fiber, and feature a central core of either polypropylene or stainless steel. The construction involves winding yarns to create a porous structure that effectively captures particulates.

| How It Works |
| String wound filter cartridges feature a gradient density construction where the winding pattern results in tighter filtration at the core and looser filtration on the outside. This design captures larger particles at the outer layers while finer particles are filtered out as the liquid progresses through the cartridge. This gradient density increases the filter’s dirt-holding capacity and extends its service life |
