Filtermart™ String Wound Filters
Buy String Wound Filters Online
String-wound filters give classic and highly effective depth filtration when industrial process waters, heavy viscous fluids, or liquid chemicals carry huge amounts of suspended solids. The string-wound filter elements are crafted by precision winding continuous textile yarns around a perforated central core. This winding technique creates a true graded density depth structure where the outer layers can easily trap the larger particles while the inner layers can capture finer contaminants down to the central core.

This depth design easily prevents surface blinding and allows the cartridge to hold a huge amount of dirt, sand, rust, and pipe scale before it reaches terminal pressure drops. The industrial string wound filters are used widely across municipal water treatment plants, electroplating operations, and chemical processing units, and also in the oil and gas sector fluid loops because they are extremely versatile and come with low initial cost and high dirt-holding capacity.
At FilterMart, we offer a wide range of industrial string wound filter cartridges that are engineered to meet the OEM specifications. These are available in standard and Big Blue length and diameter, and these elements are crafted under strict quality controls to make sure there is consistent winding tension, which prevents channeling or particle unloading when the pressure spikes. No matter if you need rough clarification for raw water intake or fine polish filtration for process chemicals, we at FilterMart offer string-wound filters that provide you with trustworthy and single-pass fluid purification. You can go through our catalogue to select different core materials and yarn fibers that are engineered to optimize the process.
