Feature-Tec specially designed a patented internal frame with a spiral welding structure to prevent string wound cartridges being easily getting deformed. This cellular structure prevents side leakage, reduce pressure drop, increase pollutants holding capacity and ensure high filtration accuracy. Feature-Tec String Wound Filter Cartridges can effectively filter suspended micropollutants or particles from low viscosity and low impurity count liquid or gas streams. String wound cartridges are widely used in organic solvents, food & beverages, electronics, and various other industries.

 

String Wound Filter Cartridge Product Features:

• The cellular structure with compact inside and unconsolidated outside can realize deep filtration of liquid to effectively remove impurities

• Gradient filtration pore structure ensures maximum filtering accuracy

• Non-standard design is available based on customer’s requirements

 

Customers can:

     • Choose spiral welding framework to ensure element has sufficient stiffness, high pressure differential environment

     • Choose from a range of materials based on chemical compatibility for the specific process fluid

     • Choose from a range of pore diameter/ micron ratings

     • Choose from a range of connection types based on your vessel design
