String Wound Filter Cartridge 1 Micron 40 Inch: Ultra-Precision Wound Depth Filter For Critical Industrial Liquid Purification
Introduction:If you are sourcing String Wound Filter Cartridge 1 Micron 40 Inch for ultra-precision industrial liquid filtration, micro-particle removal and high-standard pretreatment of ultra-pure water, this polypropylene yarn wound filter delivers stable 1 micron filtration accuracy. Built with multi-layer gradient winding design, it effectively captures fine silt, micro rust particles, colloidal pollutants and tiny suspended solids that larger micron filters fail to intercept. Featuring washable and reusable structure with excellent mechanical strength, it serves as the critical final pre-filter barrier to protect RO and UF membrane systems from micro-particle fouling. Widely used in semiconductor ultra-pure water, pharmaceutical auxiliary water, high-end beverage production, fine chemical liquid clarification and high requirement electroplating solution filtration projects.

Product Overview
String Wound Filter Cartridge 1 Micron 40 Inch is the highest precision reusable depth filter within standard string wound series. It is manufactured by winding high-purity continuous polypropylene yarn layer by layer onto a reinforced rigid PP inner core. Precise control of winding tension creates outer-loose and inner-dense gradient structure, achieving genuine three-dimensional depth filtration rather than simple surface blocking. Standard dimension: 40 inch length, 60mm outer diameter and 30mm inner diameter, fully compatible with all mainstream 40-inch filter housings for quick replacement. Compared with 5μm,10μm and 20μm string wound cartridges, this 1μm grade targets micro impurity interception for high-demanding working conditions. The rigid support core prevents collapse under pressure, and PP yarn maintains good resistance to weak acid and weak alkali, suitable for critical precision liquid processing.
Working Principle
String Wound Filter Cartridge 1 Micron 40 Inch adopts outside-in gradient depth filtration principle. When industrial liquid flows through multi-layer wound yarn, coarse impurities such as sand and rust flakes are trapped by outer loose yarn layers. Medium suspended particles are intercepted in the middle winding layers. Micro particles above 1 micron are deeply captured by compact inner yarn layers. This layered interception distributes contaminants evenly in the whole filter body, maximizing dirt holding capacity and slowing pressure rise. The high-strength PP inner core provides reliable mechanical support, maintaining filter shape integrity under continuous flow and pressure fluctuation, and guaranteeing consistent ultra-fine filtration performance for long-time continuous running.

FAQ
Q1: What is the difference between 1μm and 5μm string wound filter cartridge?
A1: The 1μm model can intercept much smaller micro particles, which is used for ultra-pure water and high precision liquid scenarios. Its pore structure is tighter, so dirt holding capacity is lower than the 5μm grade.
Q2: How many cleaning cycles can the 1μm string wound filter support?
A2: Only suitable for low-contamination liquids. It can be rinsed and reused 2-3 times. Once colloidal pollutants block yarn gaps permanently, replacement must be carried out.
Q3: What liquid environments are not suitable for this filter?
A3: Not fit for strong acid, strong alkali or heavy oily liquids. These media will damage polypropylene yarn and cause permanent blockage.
Q4: Are custom specifications available?
A4: Yes, 10/20/30/40 inch lengths and full micron grades are available for bulk project orders.
