Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 specializing in high-performance filtration solutions. Our Sintered Powder Metal Filter for Water Treatment Applications is engineered to deliver exceptional durability, backwashability, and corrosion resistance, making it the ideal choice for demanding water treatment processes. With annual export value exceeding US$5 million and a global footprint spanning North America, Europe, Asia, and beyond, we bring decades of expertise to every filter we produce.
Product Overview
This sintered powder metal filter is manufactured by compressing and sintering metal powders (stainless steel 316L, bronze, or other alloys) into a porous structure with controlled pore sizes. The result is a robust, rigid filter element that can withstand high temperatures, high pressures, and aggressive chemical environments. Its unique design allows for effective backwashing, enabling easy cleaning and extended service life—ideal for continuous water treatment operations.
Key Features & Benefits
- Backwashable Design – Reverse flow cleans the filter without disassembly, reducing downtime and maintenance costs.
- Superior Corrosion Resistance – Made from 316L stainless steel, resistant to chlorides, acids, and alkalis, suitable for harsh water chemistries.
- High Mechanical Strength – Sintered structure provides rigidity and resistance to pressure surges, ensuring long-term reliability.
- Uniform Pore Distribution – Consistent filtration performance with grades from 1 to 200 microns, removing suspended solids, sand, rust, and other contaminants.
- High Temperature Tolerance – Operates from -200°C to 600°C, suitable for hot water or steam applications.
- Customizable Shapes & Sizes – Available as tubes, discs, plates, and custom configurations to fit existing housings.
- Eco-Friendly & Reusable – Washable and reusable, reducing waste compared to disposable cartridge filters.

Frequently Asked Questions
A: It depends on the turbidity of the water. Typically, backwashing is performed when the pressure differential reaches 1-2 bar. For most applications, once every few days to weeks is sufficient.
A: Yes, the sintered metal filter has low flow resistance due to its high porosity. Flow rate capacity depends on the size and micron rating; we can provide specific data for your application.
A: Yes, when made from 316L stainless steel, it offers excellent resistance to chloride corrosion. For extreme conditions, Hastelloy is available upon request.
A: With proper backwashing, the filter can last several years. The sintered structure is robust and does not degrade like disposable media.
A: Yes, we offer flanges, threaded ends, tri-clamp fittings, and other custom connectors to match your existing piping.
A: Absolutely. We provide sample filters for evaluation. Please contact us with your requirements.
A: Our factory follows strict quality management practices. Specific certifications are available upon request—please inquire for details.
A: Standard sizes are typically shipped within 15-20 working days. Custom orders may require 25-30 working days depending on complexity.
