As a leading manufacturer with over 25 years of expertise, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly presents our 316L Stainless Steel Metal Powder Sintered Filter with a precise 0.5 micron pore size, 20mm outer diameter, and 100mm length. This filter element is engineered to deliver exceptional filtration performance in demanding industrial environments, leveraging our deep understanding of metal powder sintering technology and strict quality control. With annual export values exceeding US$5 million and shipments to major global markets, our products are trusted by customers across North America, South America, Europe, Asia, and beyond.
Our sintered filter is manufactured from high-quality 316L stainless steel powder, which is compressed and sintered under controlled conditions to create a uniform porous structure with excellent mechanical strength and corrosion resistance. The 0.5 micron pore size ensures reliable removal of fine particles, making it ideal for applications requiring high purity levels. The compact dimensions of 20mm OD and 100mm length allow for easy integration into existing filtration systems, while the robust construction ensures long service life even under high pressure and temperature fluctuations.
Key features of this filter include:
- High Filtration Precision: 0.5 micron absolute rating – captures particles down to sub-micron level, suitable for fine filtration of liquids, gases, and chemicals.
- 316L Stainless Steel Material: Excellent corrosion resistance against acids, alkalis, and organic solvents; withstands high temperatures up to 500°C (932°F) in oxidizing environments.
- Uniform Pore Distribution: Sintering process ensures consistent pore size and shape, minimizing pressure drop and maximizing dirt holding capacity.
- High Mechanical Strength: Can withstand differential pressure up to 30 bar (435 psi) or more, depending on specific configuration.
- Customizable Dimensions: While standard size is 20mm OD x 100mm length, we can produce various lengths, diameters, and end fitting types (e.g., threaded, flanged, or plain ends) to meet your system requirements.
- Easy to Clean & Reusable: The metal sintered structure can be cleaned by backwashing, ultrasonic, or chemical methods, offering long-term cost savings compared to disposable filters.
- Wide Application Range: Suitable for petrochemical, pharmaceutical, food & beverage, water treatment, gas purification, hydraulic systems, and more.

The 316L stainless steel powder sintered filter offers distinct advantages over other filter media. Its all-metal construction eliminates the risk of fiber shedding or media migration, which is critical for clean processes. The high porosity (typically 30-50%) provides low flow resistance, reducing energy consumption in pumping systems. Additionally, the filter can be regenerated multiple times, lowering total cost of ownership. Whether you need to filter aggressive chemicals, high-temperature gases, or sterile liquids, this filter element delivers consistent performance.
At Anping Boli, we have been manufacturing wire mesh and sintered metal products since 1998. Our factory is located in Hengshui, Hebei – the hardware wire mesh capital of China. We export to more than 15 countries and regions, with annual export value reaching US$5-10 million. Our team of experienced engineers can provide customized solutions to meet your specific filtration requirements. We use advanced sintering furnaces and precision testing equipment to ensure every filter meets strict quality standards. Each batch is tested for pore size distribution, burst pressure, and flow rate before shipment.
We are committed to delivering reliable products that enhance your process efficiency. Whether you are a distributor, OEM, or end-user, we welcome your inquiry. Contact us today to discuss your filtration needs – we can provide samples, technical drawings, and bulk pricing. With our flexible production capacity and fast shipping from Tianjin, Qingdao, Shanghai, or Foshan ports, you can trust us as your long-term partner.
Frequently Asked Questions
-
Q: Can this filter be used for water filtration?
A: Yes, the 316L stainless steel sintered filter is suitable for water filtration, including reverse osmosis pre-filtration, coolants, and process water. Its corrosion resistance ensures long life in water applications. -
Q: What is the maximum pressure drop allowed?
A: The filter can withstand a differential pressure of up to 30 bar (435 psi) at room temperature. For higher pressure requirements, we can design thicker walls or reinforced structures. -
Q: How do I clean the filter?
A: Cleaning methods include backwashing with a clean fluid, ultrasonic cleaning, or chemical cleaning (e.g., with mild acids or solvents). Avoid using abrasive tools that may damage the sintered surface. The filter can be reused many times if properly cleaned. -
Q: Do you offer custom sizes or end fittings?
A: Absolutely. We can customize outer diameter, length, wall thickness, and end connections (e.g., threaded, flanged, or capped ends). Please provide your requirements for a quotation. -
Q: Is the 0.5 micron rating absolute or nominal?
A: The rating is typically based on bubble point test and can be considered absolute for most applications. We can provide a detailed test report upon request. -
Q: What is the typical porosity of this filter?
A: The porosity is approximately 30-50% by volume, depending on powder size and sintering parameters. This provides a good balance between flow rate and filtration efficiency. -
Q: Can I get a sample order before bulk purchase?
A: Yes, we offer sample orders for evaluation. The sample cost is reasonable, and we can deduct it from the first bulk order. Contact us for details. -
Q: What certifications do you have?
A: Our factory operates under a strict quality management system. Specific certifications can be provided upon request, but we recommend verifying your requirements with our sales team.
