String Wound

The String Wound filter offers exceptional sediment removal for a variety of liquids. Crafted with precision from durable fiber materials such as polypropylene or cotton, this filter cartridge ensures optimal filtration, clarity, and longevity for your water or industrial applications. Its robust construction makes it ideal for both residential and commercial systems.

Filter Pump's string wound cartridge filters are manufactured using a high-speed, continuous wind process that creates a superior, one-piece filter with hundreds of diamond-shaped tunnels that get progressively smaller from the outer diameter to the core.

Finer particles are progressively trapped as fluid travels to the center of the filter, allowing for much greater retention capacity than that associated with straight surface filter media of the same dimensions and porosity.

There are wide choices of porosities, lengths, and diameters, along with a wide selection of wind and core materials so you can select the appropriate combination for your filtration needs.

Wind materials include standard, fibrillated, FDA and utility-grade polypropylene, natural cotton, bleached cotton, rayon, polyester, nylon, modacrylic, and heat-cleaned glass fiber. Core materials include polypropylene, tin-plated steel, 304 stainless steel, and 316 stainless steel.
