Filter Structure

Stainless Steel Sintered Mesh Filter, also called Metal Mesh Sintered Filter, Alloy Mesh Filter, Sintered Layer Filter, along with porous powder sintered filter element, fiberglass sintered filter element, and PP/PE sintered filter element, all belong to the broad category of sintered filter elements.

The sintering mesh filter usually has five layers of stainless steel woven wire mesh, including one protective layer, one filter layer, one separating layer, and two supporting layers. Can also add a skeleton layer according to the using conditions sometimes.



Here are the functions of each layer.

Protective Layer--80~100μm

With a high mesh density, its main function is to intercept large particulate impurities, preventing them from entering the next filter structure, serve as the preliminary filtration and protection.
 

Separating Layer--40~60μm

Pre-filtering the medium-sized particles, separating the fluid, prevents localized clogging. It can adjust the flow rate of the filter media to reduce the filter pressure on the main filter layer, and extend the sintered mesh filter's service life.
 

Filter Layer--2~20μm

With a uniform pore size distribution, it is used to control the filtration precision, ensuring stable filtration from 1 to 300 microns, serve as the main filtration function.
 

Supporting Layer--200~300μm

High-strength coarse metal wire mesh, provides mechanical strength, increases the pressure corrosion and stability of the sintered mesh filter element. To prevent the deforming or cracking of the main filter layer under high pressure.
 

Skeleton Layer--thickness 1~2mm

High thickness metal plate, espacially suitable for the high pressure working condition. Withstand the system pressure shocks, to prevent interlayer misalignment and
ensure the sinter filter' shape stability, serve as a whole supporting function in the sintered mesh filter cartridge.

Special Features of Sintered Mesh Filter
 

The stainless steel sintered mesh filter cartridge as an advanced filter element, has many advantages compared to ordinary filter elements like fiberglass, paper and normal metal mesh material.

High Precision

The precision of the sintered metal mesh filter can be up to 1 micron, can intercept impurities such as particles and colloids effectively. Sintering mesh filter elements can filter the viscous liquid, and keep the mesh holes stable, has a uniform filtration performance.
 

High-Pressure Resistance

The compressive strength of sintered mesh filter elements reaches 30MPa, has an excellent mechanical strength. It can withstand the pressure impact, and the structure is not easy to deform, metal sinter filter has a great performance in high-pressure working conditions.
 

High Temperature Resistance

The seams and the end cover of the sintered mesh filter are used with a metal welding process, rather than adhesive bonding. The using temperature of stainless steel material can up to 600℃, and some other alloy materials can be much higher.
 

High Corrosion Resistance

Stainless steel has higher corrosion resistance compared with fiberglass or paper, and has a longer service life in strong acid and alkali environments.
 

Washed and Reused

The sintered mesh filter elements can be washed, like backwashing, ultrasonic cleaning or high-temperature roasting. And can keep a good filter performance after washing, thereby can be reused and have a long service life, and cost saving.

Application

Petrochemical Industry

In petrochemical systems, a stainless steel sintered mesh filter delivers stable filtration under high pressure, high temperature, and corrosive media. Its multi-layer metal structure offers reliable particle retention for catalysts, polymers, solvents, and refined fuels. A sintered metal mesh filter maintains consistent flow rates while reducing downtime, making it a trusted choice for long-cycle operation in cracking units, refinery pipelines, and chemical processing equipment.

Biopharmaceutical Processing

Biopharma processes demand clean, stable, and non-shedding filtration. A sintered mesh filter element provides precise control of particle size while withstanding repeated steam sterilization and chemical cleaning. Its stainless-steel construction prevents media migration, which is critical in fermenters, purification lines, buffer preparation, and gas filtration. The durable design of a metal sintered filter helps maintain product purity and reduces the cost of frequent filter replacement.

Metallurgy & Forging

In metallurgy and forging plants, filtration must handle heavy contaminants and continuous high-load operation. A sintered mesh filter cartridge is widely used for hydraulic oil, lubrication systems, and gas-solid separation under harsh conditions. Its rigid, sintered structure resists deformation, ensuring stable filtration efficiency even with large pressure spikes. This long-service-life solution helps protect machinery, improve system cleanliness, and keep production running smoothly.

Wind Power Generation

Wind turbine hydraulic systems require dependable filters to protect gearboxes, lubrication circuits, and pitch-control units. The robust design of a stainless steel sintered mesh filter prevents blockages caused by fine particles or moisture, especially in remote installations where maintenance is costly. A sintered metal mesh filter maintains low pressure drop and dependable flow performance, supporting stable turbine output and extending component service life.

Food & Beverage Processing

For beverage, dairy, and food-grade liquid processing, a sintered mesh filter offers clean and repeatable filtration without flavor contamination. Its stainless-steel construction is easy to clean and suitable for CIP/SIP procedures. The uniform pore structure of a sintered mesh filter cartridge ensures stable flow and efficient removal of fine particles from syrups, brewing liquids, edible oils, and process water. Its durability and hygiene compliance make it a long-term solution for modern food production lines.
