STRING WOUND DEPTH FILTER CARTRIDGE
String wound filter cartridge is a type of depth cartridge filter that is made by weaving yarn around a core. Microfibers are twisted and twined together to form a yarn. This yarn is woven in a honeycomb-shaped weave around the core such that it forms a gradient structure to allow better filtration. The quality of a wound filter cartridge hugely depends on the type of yarn that is used to make the filter. The material of the core and a controlled manufacturing mechanism that produces a precise micron rating also contribute.
String-wound filter cartridges have come a long way and provide a very efficient and cost effective solution. Some of the benefits are:
New melt-spinning and yarn forming process - no chemicals to leach out
Continuous filaments - no short fibers means no media migration
High structural stability - no shifting of media, excellent knife-edge sealing
Random yarn structure - gives improved filtration efficiency
Higher void-to-solid ratio - more bulky yarn gives increased dirt holding capacity
Lower pressure drop - liquid flows through the entire yarn structure
Firmer structure - gives improved resistance to particle unloading
