The string wound filter cartridge is a deep filter element with good air tightness. It is made of textile fibers according to a specific process and tightly wound on a porous filter element to form a honeycomb structure with sparse outside and dense inside. Due to its extremely high structural strength, it can withstand higher PSID and harsh working conditions. The dirt it filters is not limited to the surface, but can penetrate deep into the filter element. It can effectively remove impurities such as suspended matter, rust, and particles in the fluid.
Description
With good winding technology, string wound filter cartridges can show the filtering effect of deep filter material. The ideal structure is to become denser from the outside to the inside. Therefore, during the winding process, the density of the filter material must be accurately controlled by controlling the thickness of the wire or adjusting the winding tension. Only with this kind of wound filter element with dense inner and sparse outer structure can the deep filtering effect of deep filter material be achieved, thereby effectively improving the filtering efficiency and intercepting more polluted particles.
The filtering accuracy of the string wound filter cartridge is determined by the thickness of the wire and the winding density. The finer the wire, the tighter the winding, the smaller the pores and the higher the filtering accuracy; on the contrary, the thicker the wire or the looser the winding, the lower the filtering accuracy. At the same time, the filter material must maintain its specific structure and pore size during the filtering process to ensure stable and uniform filtering quality.
Features of String Wound Filter Cartridges
Our string wound filter cartridges use a structured open outer layer and a tight inner layer to provide true deep filtration with high dirt holding capacity and extremely low media migration rate.
- High Dirt Holding Capacity
The filter is designed to handle large amounts of dirt, making it effective for long-term filtration.
- High Temperature Resistance
It can withstand temperatures up to 120ºC, making it suitable for high-temperature applications.
- Broad Chemical and Temperature Compatibility
This filter is versatile and works with a variety of chemicals and fluids across a wide temperature range.
- Longer Service Life
The design and materials used contribute to a longer lifespan, making it more cost-effective over time.
