As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory brings decades of expertise in producing high-performance filtration solutions. Our Copper Powder Sintered Filter for Compressed Air is engineered to deliver a 10 micron filtration accuracy while handling pressures up to 25 bar — making it an ideal choice for removing oil aerosols and particulates from compressed air streams. With an annual export value exceeding US$5 million and a global client base spanning North America, Europe, and Asia, we are committed to providing reliable, cost-effective filtration that keeps your pneumatic equipment running smoothly.
This filter is crafted from high-purity copper powder that is sintered under controlled conditions to form a porous, rigid structure. The result is a self-supporting, corrosion-resistant element that can be repeatedly cleaned and reused, significantly reducing replacement costs. Whether you need to protect sensitive instruments, valves, or pneumatic tools, our sintered filter offers consistent performance with minimal pressure drop.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
Q: Can this filter be cleaned and reused?
A: Yes, the copper sintered element is fully cleanable. We recommend backwashing with compressed air or ultrasonic cleaning with a mild solvent. Avoid using abrasive tools that may damage the porous structure. -
Q: What is the oil removal efficiency for 10 micron rating?
A: The filter removes 99.9% of liquid oil droplets and solid particles down to 10 microns. For finer oil mist, a 0.01 micron coalescing filter may be added downstream. -
Q: Is this filter suitable for breathing air applications?
A: This filter is designed for industrial compressed air; it does not remove carbon monoxide or other gases. For breathing air, please consult with our technical team for specific recommendations. -
Q: What connection types are available?
A: We offer standard NPT, BSP, flanged, and custom connections. Please specify your requirement when ordering. -
Q: Can I use this filter for other gases besides air?
A: Yes, the copper sintered filter is chemically resistant to many gases, but compatibility should be verified for aggressive media. -
Q: How long does the filter last before replacement?
A: With regular cleaning, the filter can last for years. The lifespan depends on operating conditions (contaminant load, temperature, pressure). We recommend periodic inspection. -
Q: Do you provide samples for testing?
A: Yes, we offer sample orders. Please contact our sales team with your requirements. -
Q: What is the minimum order quantity?
A: For standard sizes, MOQ is 10 pieces. Custom sizes may have a higher MOQ. We are flexible for bulk orders.
