String-wound Depth Cartridges

String-wound depth cartridges, also known as string wound filter cartridge or yarn filter. It is made of specific materials such as polypropylene PP wire and absorbent cotton wire, which are wound on polypropylene and stainless steel porous skeleton according to regulations to form a dense fiber layer, so that impurities are intercepted when liquid and gas flow through.

✅ Gradient dense winding design to achieve layered interception:

Our string-wound depth cartridge adopts multi-stage density control winding technology, with loose outer layer and tight inner layer, forming a step-by-step interception structure, which can efficiently capture large particles to fine impurities.

✅ No deformation, no chipping, pressure and impact resistance:

Selected high-tension fiber wire, tight and uniform winding, not easy to deform or disintegrate even under high pressure or intermittent flow rate impact, avoiding secondary pollution.

✅ Strong compatibility, suitable for a variety of liquid media:

Polypropylene material can withstand acid and alkali, cotton thread with stainless steel skeleton can be used in organic solvents and high-temperature fluid environments, suitable for different working conditions.

✅ Support precision customization to meet the needs of process differentiation:

Accuracy, length, and material can be customized according to user equipment interface, filtration rate, viscosity, impurity type and other parameters to adapt to a wider range of working conditions.
