String- and blanket-wound filter cartridges allow for low pressure drops, high flow rates, temperatures up to 125°F, and longer filter life. These string-spun filters are made with synthetic material tightly wound in two layers to trap dirt, rust, and sediment. These filter cartridges fit compatible filter housings. String-wound and blanket-wound filter cartridges provide filtration for potable water, food processing, and electroplating applications.
