Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in precision filtration solutions. Our Polypropylene Corrugated Filter Element, 20 Micron, 2.5-Inch Outer Diameter, 40-Inch Length is engineered to deliver reliable, high-flow sediment removal across a wide range of industrial and commercial liquid filtration applications. With over two decades of manufacturing experience and an annual export value exceeding US$5 million, we are proud to offer this durable, cost-effective filter cartridge that meets the rigorous demands of global markets.
This filter element features a corrugated (pleated) polypropylene design that maximizes surface area, resulting in higher dirt-holding capacity and longer service life compared to standard melt-blown or string-wound filters. The 20-micron nominal rating provides effective removal of suspended solids, rust, sand, silt, and other particulate matter, making it an ideal choice for pre-filtration, process water, reverse osmosis protection, and more. Manufactured in our Hengshui, Hebei facility, every cartridge undergoes strict quality control to ensure consistent performance.
Below we detail the key features, technical specifications, and benefits that make this filter element a standout solution for your filtration needs.
Key Features & Benefits
- High Filtration Efficiency: 20 micron absolute/nominal rating ensures reliable removal of particles while maintaining high flow rates.
- Corrugated Pleated Design: Large effective filtration area (typically 3-5 times that of standard depth filters) reduces pressure drop and extends service intervals.
- All-Polypropylene Construction: Chemically resistant to many acids, alkalis, and solvents; suitable for a wide pH range (2-13).
- Standard Dimensions: 2.5-inch outer diameter, 40-inch length – compatible with most industry-standard filter housings.
- Thermal Bonding: No adhesives or binders used; minimizes extractables and media migration.
- Low Pressure Drop: Optimized pleat geometry ensures energy-efficient operation.
- Versatile Applications: Ideal for water treatment, food & beverage, chemical processing, oil & gas, pharmaceuticals, and more.
- Customizable Options: End caps (DOE, gasketed, etc.), inner core, and gasket materials available upon request.

Detailed Product Advantages
1. Enhanced Surface Area for Longer Life: The corrugated pleated structure provides up to 5 times more filtration area than conventional depth filters of the same dimensions. This translates to higher dirt-holding capacity, fewer cartridge changes, and reduced downtime.
2. Chemical Compatibility: Polypropylene offers excellent resistance to a broad spectrum of chemicals, including acids, bases, and many organic solvents. This makes the filter element suitable for aggressive process fluids in chemical and pharmaceutical industries.
3. Low Extractables: Thermal bonding technology ensures that no adhesives, binders, or surfactants are used during manufacturing. This minimizes the risk of media migration and extractables, preserving the purity of your filtrate.
4. Consistent Micron Rating: Each filter element is manufactured with precise control over pore size distribution, ensuring reliable 20 micron removal efficiency batch after batch.
5. Easy Installation and Replacement: Designed to fit standard 2.5-inch OD housings with a 1-inch ID core. The double open end configuration allows quick installation in most commercial and industrial filter vessels.
6. Environmentally Friendly: Polypropylene is a recyclable material. Used cartridges can be incinerated or recycled, reducing waste disposal concerns.
7. Wide Range of Applications: From municipal water treatment to food processing, from cooling tower filtration to reverse osmosis pre-treatment, this filter element delivers reliable performance in demanding environments.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a corrugated filter element and a standard melt-blown filter?
A: A corrugated (pleated) filter element has a much larger surface area due to its folded design, which allows higher flow rates, longer service life, and lower pressure drop compared to depth-type melt-blown filters. It is also more resistant to channeling and media migration. -
Q: Can this filter element be used for high-temperature applications?
A: The maximum continuous operating temperature is 160°F (71°C). For higher temperatures, consult our team for alternative materials (e.g., PTFE or stainless steel). Please note that polypropylene may soften above this limit. -
Q: Does the filter element come with gaskets or end caps?
A: The standard configuration is Double Open End (DOE) without gaskets. However, we can supply gasketed end caps (with Buna-N, EPDM, Silicone, or Viton® O-rings) upon request. Please specify your requirements when ordering. -
Q: What is the typical dirt-holding capacity of this 20 micron element?
A: The dirt-holding capacity depends on the nature of the particles and the fluid. Typically, a 40-inch pleated polypropylene filter can hold 200–400 grams of sediment before reaching terminal pressure drop. Actual performance may vary; we recommend conducting a trial to determine the best replacement interval. -
Q: Is this filter element suitable for drinking water applications?
A: Yes, polypropylene is a food-grade material commonly used in drinking water filtration. However, we recommend verifying local regulations and testing for your specific water quality. Our filter elements are manufactured without adhesives to minimize extractables. -
Q: Can I use this filter element for oil or chemical filtration?
A: Polypropylene is chemically resistant to many acids, alkalis, and solvents. However, it is not suitable for strong oxidizing agents or concentrated aromatic hydrocarbons. Please consult our chemical compatibility chart or contact us for guidance on your specific fluid. -
Q: What is the minimum order quantity (MOQ)?
A: We can accommodate small orders for sample testing (e.g., 10–20 pieces). For bulk production, MOQ typically ranges from 100 to 500 pieces depending on the specifications. Contact us for a detailed quotation. -
Q: Do you provide custom sizes or end cap options?
A: Yes, we offer customization including different lengths, outer diameters, inner diameters, core materials (PP, stainless steel), and end cap styles (DOE, gasketed, flat, etc.). Lead time and pricing will be provided upon request.
Note: The specifications mentioned are typical and may vary slightly depending on manufacturing batch. All products are subject to our standard quality control procedures. For critical applications, we recommend conducting a qualification test.
