Product Description

Our sintered powder metal filters are supplied using high-temperature sintering of fine metal powders, including 316L stainless steel, 310 stainless steel, titanium, nickel, and bronze. The final filtration rating, nominal pore-size range, porosity, temperature resistance, and chemical compatibility depend on the selected material and powder grade. Powder pore sizes may range from approximately 4 to 160 μm, while the filtration rating must be confirmed for the specific design and application. These filters are suitable for polymer melt, high-temperature gas, corrosive liquid, and other demanding process filtration.

For related filtration solutions, see our Sintered Wire Mesh Filters, Sintered Metal Fiber Felt Filters, and Wedge Wire Screen Filters. For a direct comparison of materials, see our sintered metal powder filter materials guide and stainless steel alloy selection guide.

Frequently Asked Questions

Q1: What materials are available for sintered metal powder filters?

Common materials include SS316L, titanium, nickel-based alloys, and bronze. SS316L is suitable for general corrosion-resistant applications; titanium offers excellent resistance to strong acids and chlorides; nickel alloys perform well in high-temperature, corrosive environments; bronze is typically used for air, water, and fuel filtration.

Typical filtration ratings range from 0.1 to 100 μm. We define accuracy based on the absolute filtration rating, supported by bubble point test data to verify that no particles larger than the nominal pore size pass through. Bubble point tests can be arranged for each batch, with reports available upon request.

The uniform porous structure of sintered powder provides stable permeability. Pressure drop increases gradually with flow rate, making these filters suitable for precise liquid filtration, gas distribution, aeration, and fluidization applications. Actual performance depends on pore size, material, and medium viscosity.

Yes. Beyond standard filter cartridges, we supply porous plates, tubes, discs, diffusers, spargers, and fluidized bed distributor plates. Dimensions such as outer diameter, length, wall thickness, and pore size can be customized according to technical drawings or samples.
