Product Description

String Wound Cartridge is made of fibre wound around a porous framework, after carding & spinning into roving they are wound into cartridges with carefully controlled micron rating. From raw materials to finished products, we are control  the quality and filtration characteristics.  

Feature-tec specially designs a patented internal frame with spiral welding structure to solve the disadvantage of easily getting deformed in normal string wound cartridge so as to ensure filtration rigidity. The cellular structure with compact inside and unconsolidated outside and gradient filtration pore structure effectively avoid side leakage and traditional disadvantages in normal string wound cartridge so as to reduce pressure drop, increase pollutants holding capacity and ensure high filtering accuracy. Due to this special structure, the cartridge can effectively filter suspended micropollutants or particles from liquid or gas and is normally used for filtering liquid with low viscosity and low impurity content. It is widely applied for organic solvent and plating solution treatment in food & beverage and electronics industries, and industrial oil filtration in petrochemical, pharmaceuticals, hydraulic oil and lubricating oil industries.

     String Wound 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;

According to the requirements of the operating environment, customers can:

choose spiral welding framework to ensure element has sufficient stiffness, suited for high pressure differential environment.
choose from a range of material with good compatibility for specific filtration fluid
choose from a range of pore diameter for specific needs
choose from a range of sizes for the connections, from Size 222 to 226
choose from single-opening for higher filtration accuracy or double-opening for a lower requirement

Non-standard design is available according to customer’s actual operating environment.

Primary performances:

Accuracy and flow rate

 

Accuracy and flow rate
Filtration accuracy(um)	1	3	5	10	20	30	50
Maximum flow rate(L/m)	9	12	18	30	37	42	44

Note: the measured cartridge length is 250mm,pressure difference is 0.02MPa,tested medium is clean water and temperature is room temperature.Use these parameters to deduce flow rate of other cartridges
