As a trusted manufacturer with over 20 years of specialization in wire mesh products, Anping County Boli Hardware Wiremesh Products Factory proudly presents our 316L Sintered Wire Mesh Filter Element with 20μm precision and exceptional high temperature resistance up to 500°C. This filter element is engineered to deliver robust performance in demanding filtration environments, combining superior mechanical strength with excellent corrosion resistance. Whether you need to separate fine particles from aggressive chemicals or filter hot gas streams, our sintered mesh elements offer a reliable and long-lasting solution.
Our manufacturing process involves sintering multiple layers of 316L stainless steel wire mesh under controlled temperature and pressure, creating a rigid, porous structure with uniform pore distribution. The result is a filter element that not only achieves precise 20-micron filtration but also withstands extreme temperatures and high differential pressures. Each unit is thoroughly tested to ensure consistent quality and performance.
Key Features & Technical Specifications
- Material: 316L stainless steel – excellent resistance to pitting, crevice corrosion, and high-temperature oxidation.
- Filtration Precision: 20 μm absolute rating, capable of removing particles down to 20 microns with high efficiency.
- Temperature Resistance: Continuous operation up to 500°C, suitable for hot gas filtration, catalyst recovery, and high-temperature process fluids.
- High Mechanical Strength: Sintered structure provides rigidity and resistance to pressure surges, backwashing, and mechanical vibration.
- Easy to Clean: Can be backwashed, ultrasonically cleaned, or chemically regenerated, extending service life and reducing replacement costs.
- Customizable Dimensions: Available in various diameters, lengths, and connection types (flange, thread, ferrule, etc.) to fit your existing filtration system.
- Application Versatility: Ideal for chemical processing, petrochemical refining, oil & gas, water treatment, food & beverage, pharmaceuticals, and high-temperature dust collection.

Advantages & Customer Benefits
Choosing our 316L sintered wire mesh filter element means investing in durability and efficiency. The all-metal construction eliminates the risk of media migration, ensuring consistent filtration quality throughout the product's lifespan. Unlike disposable filter cartridges, our sintered elements can be cleaned and reused many times, significantly reducing operating costs and waste. The high temperature resistance allows you to integrate the filter directly into hot process lines without cooling, saving energy and simplifying system design.
Furthermore, the precise 20-micron pore size delivers reliable particle removal for critical applications such as catalyst recovery in chemical reactors, hydraulic oil filtration, and sterile air/gas filtration. The 316L grade offers superior protection against chloride-induced stress corrosion cracking, making it suitable for marine and offshore environments.

Frequently Asked Questions (FAQ)
-
What is the main advantage of a sintered wire mesh filter element over wound or pleated filters?
Sintered wire mesh elements provide a rigid, all-metal structure that can withstand high temperatures, high differential pressures, and aggressive chemicals. They are reusable after cleaning, offering longer service life and lower total cost of ownership compared to disposable filters. -
Can the 20μm precision be customized to other micron ratings?
Yes, we offer a range of filtration grades from 1μm to 200μm. Please specify your required micron size when inquiring, and we can adjust the sintering process accordingly. -
How do I clean a sintered metal filter element?
Common cleaning methods include backwashing with a suitable solvent, ultrasonic cleaning, or high-pressure water jet. For extreme fouling, chemical cleaning with acids or alkaline solutions may be used. Always consult our technical team for the best cleaning approach for your specific application. -
What is the maximum pressure drop allowed across the filter?
The allowable pressure drop depends on the design and operating conditions. Typically, our sintered elements can handle differential pressures up to 50 bar. However, we recommend maintaining a maximum pressure drop of 10–20 bar during normal operation to avoid structural fatigue. Please contact us for specific recommendations. -
Is the filter element suitable for high-viscosity fluids?
Yes, but the effective filtration area and pressure drop must be considered. For high-viscosity fluids, we may recommend a larger diameter or longer element to maintain adequate flow. Our engineers can help design the optimal configuration. -
Can you provide custom connection types (e.g., flanges, threads, sanitary fittings)?
Absolutely. We offer a wide variety of end connections including NPT/BSP threads, ANSI/DIN flanges, ferrule fittings, and tri-clamp connections. Please provide your connection specifications when placing an order. -
What is the typical lead time for custom orders?
For standard sizes, lead time is 15–20 working days. For custom dimensions or special connections, allow 25–30 working days. Urgent orders may be expedited upon request. -
Do you offer samples for testing?
Yes, we can provide sample units for evaluation. Please contact our sales team with your requirements, and we will arrange a sample along with a quotation.
