The String wound water filter element is a deep filtration filter element used for low viscosity, low impurity quality filtration. It is made of textile fibre threads, wound precisely on the porous skeleton according to a specific process, and has a honeycomb structure with a sparse outside and a dense inside. This design effectively removes suspended matter, particles and other impurities in the fluid, and has excellent filtration characteristics.

Molding characteristics

Special material roving is cross-wound onto the skeleton to form thousands of diamond-shaped holes. The filtration layer consists of yarn wound with specific parameters. The inner part of the cartridge forms a diamond-shaped curved channel from the surface to the inner part, from big to small. The size of the diamond-shaped holes in the innermost layer of the cartridge determines its precision. The precision of the cartridge is directly proportional to the size of the diamond-shaped hole; larger holes indicate lower precision, and smaller holes indicate higher precision.

Filtration principle and effect

(1) Interception of particles by fibers.

Liquid from the outer layer of the cartridge through the narrow and long and curved channel into the inner layer of the cartridge, small particles will be intercepted by the fiber fluff on the wall of the channel.

• the settling effect of particles.

 When the liquid passes through the roving channel in the filter element, the particles hit the roving trunk or fiber fluff back and forth, and settle in the roving channel due to gravity.

Type of impurity removal

It can effectively intercept harmful impurities in water such as particulate matter, rust, colloidal substances, sand, bacterial clusters, etc. Depending on the selected filtration precision, there are differences in the interception efficiency of harmful impurities, and it is often used as a pre-treatment cartridge in the filtration system.

Filtration characteristics

The cross-section of String wound filter cartridge with different precision has a fixed number of channels, and after the filtration precision is determined, the number of channels in the length direction of the cartridge will increase or decrease accordingly with the different lengths of the cartridge. The total number of channels of the cartridge = the number of cross-section channels × the number of longitudinal channels × 2 The higher the precision of the wire-wound cartridge, the higher the number of cross-section channels and the number of longitudinal channels, the more the total number of channels of the cartridge. Therefore, the increase of filtration precision of wire-wound cartridge, its ability to filter small particles is improved, but the filtration channel is also correspondingly more, which ensures the filtration process of the cartridge and improves the filtration precision of the cartridge under the lower pressure difference.

Difference between Melt blown filter

Compared with PP melt blown cartridge, String wound water filter has stronger dirt-holding capacity and longer service life, especially in the industrial field.
