Introduction to AmeriFil Polyester Yarn Filters
When it comes to industrial liquid filtration, reliability and versatility are paramount. Purecowater is proud to offer AmeriFil Polyester Yarn string wound filter cartridges—a premier choice for depth filtration applications. These filters are engineered to provide superior dirt-holding capacity and precise micron ratings, making them an essential component in protecting downstream equipment and ensuring process quality.
The AmeriFil Polyester Yarn cartridge is constructed using a precise, continuous winding pattern around a central core. This design creates a true depth filter with a graded density structure—looser on the outside to trap larger particles and tighter on the inside to capture finer sediments. This structural integrity ensures consistent performance even under varying process conditions.
Why Choose Polyester Yarn?
While polypropylene is a common filtration medium, Polyester offers distinct advantages for specific industrial environments. It is the material of choice when higher temperature resistance or specific chemical compatibility is required.
Key Benefits
- Higher Temperature Resistance: Polyester yarn can typically withstand higher operating temperatures compared to standard polypropylene, making it suitable for hot water or process fluid applications.
- Chemical Compatibility: Excellent resistance to organic solvents, petroleum oils, and oxidizing agents.
- High Dirt-Holding Capacity: The depth filtration design allows the cartridge to capture particles throughout the entire cross-section of the filter, not just on the surface.
- Cost-Effective: AmeriFil cartridges offer an economical solution for pre-filtration and clarification without sacrificing quality.

Performance Data
AmeriFil Polyester string wound filters are designed to minimize pressure drop while maximizing retention. This balance is critical for energy efficiency and extending the service life of the filter cartridges.
| Feature | Performance Characteristic |
|---|---|
| Flow Rate | Optimized for low resistance; varies by micron rating. Generally 3-5 GPM per 10″ equivalent length for aqueous solutions. |
| Efficiency | Nominal Retention Efficiency |
| Change-Out Pressure | Recommended at 25-30 PSID to prevent unloading of contaminants. |
Common Applications
The versatility of polyester string wound filters allows them to be used across a wide array of industries. They are particularly effective in scenarios where standard polypropylene cartridges might deform under heat or degrade due to chemical exposure.
- Chemical Processing: Filtration of weak acids, alkalis, and generic solvents.
- Petrochemicals: Filtration of oils, fuels, and lubricants.
- Water Treatment: Pre-treatment for Reverse Osmosis (RO) systems and general wastewater clarification.
- Metal Finishing: Filtration of plating solutions and wash tanks.
- Electronics: Pre-filtration for process water.
