Anping County Boli Hardware Wiremesh Products Factory is a trusted manufacturer with over 25 years of experience in producing high-quality filtration components. Our Sintered Metal Powder Filter Disc, 316L, 20 Micron, 3 inch Diameter, 0.5 mm Thickness is specifically designed for demanding laboratory applications where precise filtration and chemical resistance are critical. Engineered from 316L stainless steel powder, this disc offers excellent corrosion resistance, high mechanical strength, and consistent pore distribution. Whether you are filtering gases, liquids, or fine particles, our disc delivers reliable performance and long service life.
Key Features & Technical Specifications
- Material: 316L stainless steel — excellent resistance to acids, alkalis, and high temperatures, ideal for laboratory environments.
- Filtration Rating: 20 micron (nominal) — effectively removes particles down to 20 micrometers, suitable for fine filtration tasks.
- Dimensions: 3 inch diameter (76.2 mm) with 0.5 mm thickness — compact and easy to install in standard filter holders.
- High Porosity: Typical porosity of 30–50% allows high flow rates while maintaining filtration efficiency.
- Reusable & Cleanable: Can be cleaned by backflushing, ultrasonic cleaning, or chemical methods, reducing replacement costs.
- Temperature Resistance: Operates continuously up to 600°C in oxidizing environments, and higher in inert atmospheres.
- Uniform Pore Structure: Sintering process ensures consistent pore size distribution for reliable and repeatable filtration.
- Customizable Options: Available in different diameters, thicknesses, porosity levels, and filtration ratings upon request.

Frequently Asked Questions (FAQ)
Q1: Can this filter disc be used for gas filtration?
A: Yes, it is suitable for both gas and liquid filtration. The 20 micron rating is effective for particulate removal from gases.
Q2: How do I clean the sintered metal filter disc?
A: We recommend backflushing with clean solvent or water, ultrasonic cleaning, or gentle chemical cleaning depending on the contaminant. Avoid abrasive brushes that may damage the surface.
Q3: Is the disc compatible with high-pressure systems?
A: Yes, the mechanical strength of sintered 316L allows it to withstand moderate pressures. For specific pressure requirements, please consult our technical team.
Q4: What is the typical pore size distribution?
A: The 20 micron nominal rating means the majority of pores are around 20 microns, with a standard deviation of ±5 microns. Actual distribution can be provided upon request.
Q5: Can I customize the diameter or thickness?
A: Absolutely. We offer custom sizes and thicknesses. Please contact our sales team with your requirements.
Q6: Does the disc contain any binder or resin?
A: No, it is a pure sintered metal powder filter without any organic binders, making it suitable for high-temperature or high-purity applications.
Q7: What is the maximum differential pressure before failure?
A: The disc can typically withstand up to 2 bar differential pressure, but this depends on the support structure. For higher pressures, we recommend using a support mesh.
Q8: How does this disc compare to wire mesh filters?
A: Sintered powder filters offer deeper filtration and higher dirt-holding capacity compared to wire mesh, while wire mesh provides higher flow rates. The choice depends on your application.
