As a leading manufacturer with over 25 years of experience in the wire mesh and filtration industry, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Copper Powder Sintered Filter Element designed specifically for demanding chemical processing applications. This filter element delivers exceptional filtration performance at 1 micron level while withstanding high temperatures up to 300°C, making it an ideal solution for corrosive fluid filtration, catalyst recovery, and polymer processing. Our deep expertise in powder metallurgy and sintering technology ensures consistent quality and reliability, backed by our annual export value of US$5–10 million serving global markets.
This product is manufactured using high-purity copper powder that is compacted and sintered under controlled conditions to create a porous structure with uniform pore distribution. The 1 micron absolute filtration rating ensures effective removal of fine particles, while the copper material offers excellent thermal conductivity and corrosion resistance in many chemical environments. Whether you need filtration for aggressive acids, alkalis, or high-temperature gases, our sintered filter element provides long service life and easy cleanability.
Key Features & Technical Specifications
- Filtration Rating: 1 micron (absolute) – ensures high-purity filtration for critical processes.
- Operating Temperature: Up to 300°C (572°F) – suitable for hot chemical streams and high-temperature gas filtration.
- Material: 100% pure copper powder – provides excellent corrosion resistance in many chemical media, including dilute acids, alkalis, and organic solvents.
- Porosity: 30–50% – optimized for high flow rates while maintaining filtration efficiency.
- Mechanical Strength: High compressive and tensile strength – withstands differential pressures up to 10 bar (depending on design).
- Customizable Shapes: Cylindrical, disc, conical, or custom geometries – available with various end caps and connection types (threaded, flanged, or compression fittings).
- Regenerable: Can be cleaned by backwashing, ultrasonic cleaning, or chemical washing – extends service life and reduces replacement costs.

Benefits for Your Chemical Processing
- Enhanced Product Purity: The 1 micron absolute filtration ensures removal of fine catalyst particles, contaminants, and unwanted solids, improving final product quality.
- High Temperature Resistance: Withstands continuous operation at 300°C, enabling use in hot filtration processes such as polymer melt filtration, high-temperature gas cleaning, and chemical reactor outlets.
- Corrosion Resistance: Copper offers good resistance to many chemicals, including organic acids, alcohols, and dilute mineral acids, reducing the risk of material degradation.
- Long Service Life & Economical: The sintered structure is durable and can be repeatedly cleaned, unlike disposable filters. This reduces downtime and replacement costs.
- High Flow Capacity: The high porosity (30–50%) allows for high flow rates with low pressure drop, improving process efficiency.
- Customizable Design: We can tailor the shape, size, thickness, and connection type to fit your existing equipment, reducing installation complexity.

Frequently Asked Questions
-
Q: Is the 1 micron rating absolute or nominal?
A: Our copper powder sintered filter elements are rated as absolute 1 micron filtration, meaning over 99% of particles of that size are retained. This is confirmed by bubble point testing. -
Q: Can this filter withstand 300°C continuously?
A: Yes, the copper sintered filter element is designed for continuous operation at temperatures up to 300°C. However, please note that the maximum temperature may be limited by the sealing material if O-rings are used. We can provide options with high-temperature seals if needed. -
Q: What chemicals is the copper filter resistant to?
A: Copper is resistant to many organic solvents, dilute acids (e.g., acetic, formic), alkalis, and deionized water. It is not recommended for strong oxidizing acids (e.g., nitric acid) or ammonia. We can provide a chemical compatibility chart upon request. -
Q: How do I clean the filter element?
A: The sintered element can be cleaned by backwashing with clean fluid, ultrasonic cleaning, or chemical soaking (e.g., with dilute acid). The cleaning method depends on the type of contaminants. We recommend consulting our technical team for the best practice. -
Q: Can you provide custom sizes and shapes?
A: Absolutely. We offer custom dimensions, shapes (cylindrical, disc, conical, etc.), and connection types. Please provide your drawings or specifications, and we will produce accordingly. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is flexible. For standard sizes, we can accommodate small orders starting from 10 pieces. For custom designs, a minimum quantity may apply depending on complexity. Contact us for details. -
Q: How long is the delivery time?
A: Typical lead time is 15–25 working days for standard products, and 25–35 working days for custom designs, depending on the order quantity. We also offer expedited shipping options. -
Q: Do you provide samples for testing?
A: Yes, we can provide samples (paid or free depending on size) for evaluation. Shipping costs are usually borne by the customer. We also offer technical support to help you select the correct filter element.
