Product Overview
String Wound Filter Cartridge 10 Micron 40 Inch is a premium reusable depth filter designed for standard industrial fine pre-filtration. It is precisely manufactured by winding high-purity polypropylene yarn layer by layer onto a reinforced rigid PP inner core. By adjusting winding tension layer by layer, the filter forms a scientific outer-loose and inner-dense gradient structure, realizing genuine three-dimensional depth filtration instead of simple surface interception. The standard 40-inch length, 60mm outer diameter and 30mm inner diameter fit all mainstream standard filter housings for direct replacement. With stable 10μm precision, high structural strength and outstanding chemical inertness, it perfectly solves the problems of easy breakage, low precision and non-reusability of ordinary filter elements. It is an ideal cost-effective alternative for long-term industrial water pretreatment projects.
Working Principle
This 10 micron string wound filter cartridge adopts industry-standard outside-in gradient depth filtration principle. When industrial liquid flows through the multi-layer wound yarn structure, large sediment and rust scale are trapped by the outer loose yarn layers; medium suspended particles are intercepted in the middle transition winding layers; fine particulate impurities above 10μm are deeply captured by the dense inner yarn layers. The layered interception structure evenly distributes contaminants inside the entire filter body, greatly improving dirt holding capacity and avoiding rapid surface clogging. The high-strength integral PP support core effectively resists water pressure impact, preventing filter deformation or collapse during long-term continuous operation and maintaining consistent filtration stability.

FAQ
Q1: What are the differences between 10μm and 20μm string wound filters?
A1: The 10μm grade has higher filtration precision, capable of intercepting finer micro impurities, suitable for standard and high-precision pretreatment scenarios; while 20μm is more suitable for high-turbidity raw water with more coarse sediment.
Q2: How many times can the 10μm string wound filter be reused?
A2: Under clean and low-pollution working conditions, it can be cleaned and reused 3-5 times. It is recommended to replace it in time when the pressure drop rises obviously to ensure stable water quality.
Q3: Can it be used for oily water filtration?
A3: It supports low-concentration oily liquid pre-filtration. Heavy oil pollution will block the yarn gap permanently and reduce cleaning effect.
Q4: Are customized specifications available?
A4: Complete sizes (10/20/30/40 inch) and full micron grades (1/5/10/20/50/100μm) are available for bulk project orders.
