Product Overview
The PP String Wound Water Cartridge Filter (Model BS164) is a high-performance depth filtration solution manufactured by ZIBO ANDA FILTER Co., Ltd., an ISO 9001 and ISO 14001 certified facility with full in-house testing capabilities per EN779, EN1822, and ASHRAE standards.
This 10-inch cartridge features a 28mm inner diameter polypropylene core, with white PP yarn (customizable colors available) precision-wound under controlled tension to create a true depth filtration structure.Unlike surface-type filters that trap particles only on the exterior, the string-wound design features progressively tighter inner layers-loose on the outside to capture larger sediments, dense toward the core to trap finer particles. This gradient density construction enables the filter to handle varying particle sizes simultaneously, maximizing contaminant loading while maintaining consistent flow rates throughout the service life.
Each cartridge undergoes rigorous quality control, with factory batch inspection reports available for every production run. ANDA's direct manufacturing and export capabilities eliminate intermediary costs, delivering factory-direct pricing without compromising on quality.
Product Advantages
1. Superior Dirt-Holding Capacity That Reduces Change-Out Frequency
The depth filtration structure provides significantly higher contaminant loading capacity than melt-blown or surface-type cartridges-typically 2 to 3 times greater. This means fewer replacements, less downtime, and lower overall operating costs. For a facility running 24/7 operations, this translates directly into reduced labor costs and minimized production interruptions.
2. Precision 1-Micron Filtration with Gradient Density Design
The progressive winding density-loose outer layers transitioning to tight inner layers-creates a natural particle-size separation effect. Large particles (sand, silt) are captured in the outer layers, while finer contaminants (rust, sediment particles) are trapped deeper in the structure. This layered approach prevents premature surface blinding and extends the effective service life of each cartridge.
3. Broad Chemical Compatibility and Thermal Resistance
Constructed from 100% polypropylene yarn with a polypropylene core, this cartridge resists a wide range of chemicals including acids, alkalis, and solvents. Maximum operating temperature reaches 80°C (176°F), making it suitable for both ambient and heated process streams. This versatility means one product specification can serve multiple applications across your facility, simplifying inventory management.
4. Structural Integrity That Prevents Bypass and Media Migration
Precision winding on a durable polypropylene core ensures the cartridge maintains its shape even under high differential pressure conditions. The rigid construction provides reliable knife-edge sealing within standard filter housings, eliminating the fluid bypass issues common with inferior cartridges that deform under pressure. This sealing integrity ensures that 100% of the fluid stream passes through the filter media-not around it.
5. ISO-Certified Quality with Full Traceability
Manufactured in an ISO 9001 and ISO 14001 certified facility, each batch is tested to international standards. ANDA maintains complete quality documentation and factory inspection reports for every production run. For procurement professionals, this means verifiable quality assurance and full supply chain transparency.

FAQ

Common Problem
Q1: What does "1 micron" mean for this filter?
A: The 1-micron rating indicates the filtration precision-particles larger than 1 micron are effectively captured. The gradient density design means larger particles are trapped in outer layers while finer particles are captured deeper in the structure, providing thorough contaminant removal without rapid pressure drop increase.
Q2: What certifications does this product carry?
A: The product is manufactured in ISO 9001 and ISO 14001 certified facilities. ANDA maintains testing capabilities per EN779, EN1822, and ASHRAE standards. Factory inspection reports are available for each production batch.
Q3: Can this cartridge be customized for my existing housing?
A: Yes. Beyond the standard 10-inch length and 28mm inner diameter, ANDA offers custom lengths, diameters, micron ratings, and end-cap configurations. Contact our technical team with your housing specifications.
Q4: What is the minimum order quantity?
A: MOQ varies by specification. ANDA works with both wholesale distributors and direct end-users. Contact our sales team to discuss your volume requirements.
Whether you're protecting an RO system, pretreating drinking water, or maintaining industrial process quality, ANDA's 1-micron PP string wound water cartridge delivers the performance and reliability your operation demands.
