Sintered Filter Elements
Sintered Filter Elements are rigid, porous filtration components manufactured by bonding powdered metal or other filter media through a controlled sintering process. Aris Filtration supplies customized sintered filtration solutions for liquid, gas and air applications, with options including SS316L and SS304L metal media and micron ratings from 0.2 to 50 microns for demanding industrial processes.
What Are Sintered Filter Elements?
Sintered Filter Elements are porous filtration elements produced by compacting suitable powder or layered filter media and heating it under controlled conditions to create a mechanically stable porous structure. The resulting filter combines controlled pore distribution, structural strength and permeability.
In metal powder sintering, particles are bonded without completely melting the base material. This powder-metallurgy principle is widely established for producing engineered components with controlled properties.
Aris Filtration manufactures and supplies sintered filtration products for applications where conventional disposable filters may not provide the required combination of strength, cleanability, chemical resistance, permeability and filtration precision.

How Do Sintered Filter Elements Work?
A sintered filter works by allowing the process fluid, gas or air to pass through interconnected pores while retaining particles above the selected filtration rating. The pore structure is created during the manufacturing process rather than by simply coating a supporting surface.
For metal sintered elements, the manufacturing route can involve selecting powder characteristics, forming the required geometry and controlled high-temperature sintering. Aris Filtration states that its porous sintered metal elements are produced from metal powder without adhesive, followed by axial compression moulding and high-temperature vacuum sintering.
The key filtration principle is simple: The interconnected porous structure permits flow while controlling particle passage. This makes sintered filtration particularly useful where a filter must maintain its geometry under demanding process conditions.

Why Choose Sintered Filter Elements for Industrial Filtration?
Sintered filter elements can provide several advantages over conventional filtration media, depending on the process and filter design:
- Controlled filtration: Available in multiple micron ratings for different separation requirements.
- High porosity: Aris Filtration specifies porosity of up to 90% for its porous sintered metal filter elements.
- High permeability: The porous structure supports fluid or gas passage with efficient flow characteristics.
- Low pressure drop: Properly selected sintered media can provide effective filtration without unnecessarily restricting flow.
- Chemical resistance: Stainless-steel sintered media can be selected for demanding chemical environments.
- Back-flushing capability: Certain sintered designs can be cleaned by reverse flow, extending service usability.
- Mechanical stability: The sintered structure provides a rigid filter medium rather than a loose particulate bed.
- Customized construction: Dimensions and configuration can be developed around the filtration equipment and process requirements.
Aris Filtration's SS316L sintered fabric media is also described as having high porosity, stable pore geometry, low pressure drop, high dirt-holding capacity, temperature/pressure resistance and corrosion resistance.
Where Are Sintered Filter Elements Used?

How Should a Sintered Filter Element Be Selected?
Selecting the correct filter should begin with the process, rather than the micron rating alone.
Consider these parameters:
- Fluid or gas: Identify the material being filtered.
- Contaminant: Determine particle type, concentration and expected loading.
- Required micron rating: Select the filtration level based on the actual separation objective.
- Flow rate: Size the filter according to required process throughput.
- Operating pressure: Check differential and system pressure requirements.
- Temperature: Confirm that the selected filter material is suitable for the operating temperature.
- Chemical compatibility: Verify compatibility with solvents, acids, alkalis, hydrocarbons or other process chemicals.
- Cleaning method: Determine whether back-flushing, chemical cleaning or another maintenance method is required.
- Connection and dimensions: Match the element with the existing filter housing or filtration equipment.
The best sintered filter is not necessarily the finest-micron filter; it is the filter that achieves the required separation while maintaining acceptable flow, pressure drop, service life and material compatibility.
