Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in wire mesh and sintered filter products. With an annual export value of US$5 million to US$10 million, we serve clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Our 1 Year Warranty Copper Powder Sintered Filter delivers reliable 0.5 micron precision filtration, backed by a comprehensive Mill Test Report for each batch. This product is engineered to meet the demanding requirements of industrial filtration, offering both durability and consistent performance.
The filter is manufactured using advanced powder metallurgy technology, where copper powder is sintered under high temperature and pressure to form a rigid porous structure. This process ensures uniform pore distribution, high mechanical strength, and excellent resistance to thermal and chemical stress. The 0.5 micron filtration grade makes it ideal for removing fine particles from liquids, gases, and compressed air systems.
Key Features & Technical Specifications
- High Filtration Precision: 0.5 micron absolute rating ensures removal of sub-micron particles.
- Durable Sintered Copper Structure: Resists high pressure, vibration, and thermal cycling.
- Reusable & Cleanable: Can be backwashed or ultrasonically cleaned for extended service life.
- Corrosion & Oxidation Resistance: Suitable for water, oil, solvents, and mild chemicals.
- Mill Test Report Included: Each filter comes with a detailed report confirming material composition and performance.
- 1 Year Warranty: Covers manufacturing defects and ensures customer confidence.
- Customizable Dimensions: Available in various diameters, lengths, and end cap configurations.

Frequently Asked Questions (FAQ)
Q1: What is the exact filtration rating of this copper sintered filter?
A: The filter has a nominal/absolute rating of 0.5 micron, capable of removing particles down to 0.5 μm in size. Efficiency is tested per industry standards.
Q2: Can the filter be cleaned and reused?
A: Yes, the sintered copper structure is robust enough for backwashing, ultrasonic cleaning, or chemical cleaning. Proper cleaning can restore most of the original flow capacity.
Q3: What type of Mill Test Report is provided?
A: The report includes chemical composition analysis of the copper powder, sintering process parameters, porosity measurement, and bubble point test results. It is issued per batch.
Q4: Can I get custom dimensions or end fittings?
A: Absolutely. We offer customization of outer diameter, length, wall thickness, and end connections (threaded, flanged, or plain). Please provide your requirements.
Q5: What is the maximum operating temperature and pressure?
A: In inert environment, the filter can withstand up to 400°C. Maximum differential pressure depends on wall thickness; typical design handles up to 30 bar. Consult our engineers for your specific conditions.
Q6: Is this filter suitable for food or pharmaceutical applications?
A: Copper is generally not approved for direct food contact in many regulations, but the filter can be used in non-food processes (e.g., industrial water, oils, gases). For food-grade applications, we recommend sintered stainless steel filters. Please advise your application.
Q7: What is the lead time for standard orders?
A: Standard sizes are typically shipped within 7–15 working days after order confirmation. Custom designs may require 15–25 working days depending on complexity.
Q8: Do you offer samples for testing?
A: Yes, we can provide samples (paid or free depending on value) to evaluate performance in your system. Contact our sales team to arrange.
