As a trusted manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality 304 Stainless Steel Sintered Metal Filters designed for demanding high-pressure filtration applications. Our filters are engineered to withstand up to 1.6 MPa while offering precise filtration from 0.5 to 100 microns, making them ideal for industries requiring reliable particle separation under extreme conditions. With over two decades of experience and annual exports exceeding US$5 million, we deliver consistent performance and durability to global markets including North America, Europe, and Southeast Asia.
Our sintered metal filters are manufactured using advanced powder metallurgy technology, where 304 stainless steel powder is compressed and sintered at high temperatures to create a porous structure with uniform pore distribution. This process ensures excellent mechanical strength, thermal stability, and corrosion resistance. The filters are fully cleanable and reusable, offering long service life and reduced operational costs.
Key Features & Benefits
- High Pressure Capability: Rated for 1.6 MPa working pressure, suitable for hydraulic systems, chemical processing, and oil & gas applications.
- Wide Filtration Range: Available from 0.5 to 100 microns, allowing precise control over particle size removal.
- Excellent Corrosion Resistance: 304 stainless steel withstands aggressive fluids, acids, and alkalis, ensuring long-term reliability.
- Reusable & Cleanable: Can be backwashed, ultrasonically cleaned, or chemically regenerated, reducing replacement frequency.
- High Temperature Tolerance: Operates effectively from -20°C up to 400°C (depending on configuration).
- Customizable Dimensions: Available in disc, tube, cartridge, and custom shapes with threaded or flanged connections.
- Uniform Pore Distribution: Sintering process ensures consistent filtration performance and low pressure drop.
- Mechanical Strength: Rigid structure prevents deformation under high flow and pressure differentials.

Frequently Asked Questions
Q1: Can these filters be used for hot gas filtration?
A: Yes, our 304 stainless steel sintered metal filters can handle temperatures up to 400°C, making them suitable for hot gas filtration in industrial processes. For higher temperatures, we can recommend alternative materials.
Q2: How do I clean the filter after use?
A: The filters are fully cleanable. Common methods include backwashing with clean fluid, ultrasonic cleaning, or chemical cleaning with appropriate solvents. The porous structure withstands repeated cleaning cycles without deterioration.
Q3: What is the pressure drop across the filter?
A: Pressure drop depends on micron rating, flow rate, fluid viscosity, and filter size. Typically, at 1.6 MPa working pressure, the initial pressure drop is low (0.02-0.1 MPa). We provide detailed pressure drop curves for your specific conditions upon request.
Q4: Can you customize the filter shape and dimensions?
A: Absolutely. We offer custom shapes including discs, tubes, cartridges, sheets, and special geometries. Minimum order quantity may apply for custom designs. Please provide your drawing or specifications.
Q5: What is the lifespan of the filter?
A: Lifespan depends on operating conditions, cleaning frequency, and fluid characteristics. With proper maintenance, our sintered metal filters can last several years. Many customers report 2-5 years of service before replacement is needed.
Q6: Is the filter suitable for high-viscosity fluids?
A: Yes, the rigid porous structure allows filtration of high-viscosity fluids such as oils, resins, and polymers. We recommend selecting a coarser micron rating (e.g., 50-100 micron) for such applications to maintain acceptable flow rates.
Q7: Do you provide certificates or test reports?
A: We can provide material test certificates (MTC) for 304 stainless steel, proof pressure test reports, and dimensional inspection reports. Certification from third-party labs is available upon request at additional cost.
Q8: What is the minimum order quantity?
A: For standard sizes, MOQ is typically 10 pieces. For custom designs, MOQ may vary. We also offer sample orders for evaluation. Contact our sales team for details.
