String Wound Filter Cartridges

Our string wound filter cartridges, with textile fiber yarn of PP, absorbent cotton and glass fiber wound by special pattern onto Polypropylene, stainless steel or tinned steel skeleton, are structured loose outer layers and tight inner layers which can offer true depth filtration for high dirt holding capacity; and extremely low media migration to ensure temperature and chemical compatibility.   
The main advantage of the string wound filter cartridge is its exceptionally high structural strength, therefore, they can withstand severe operating conditions.
