Sintered metal filter discs are compact, disc-shaped filtration elements made from porous metal media or layered sintered wire mesh. They are used when an assembly needs controlled particle retention, defined flow paths, mechanical support, or protection for downstream components. Depending on construction, the disc may be produced from powder-sintered stainless steel, bronze, or other qualified materials, or from sintered stainless steel mesh.

A key point for buyers is that "sintered filter disc" does not describe only one construction. Powder-sintered discs and sintered mesh discs have different pore structures and flow characteristics, so the media type should be confirmed before a specification is finalized.

Manufacturer information lists material, diameter, thickness, center-hole geometry, filtration requirement, working medium, flow, pressure, temperature, and installation details as important selection inputs. NAVI Titanium can provide customized Sintered Metal Filter Discs according to these application requirements, with support for size, shape, filtration grade, material selection, and installation configuration, helping buyers obtain a specification suited to their specific equipment and operating conditions.

1. Why Choose a Disc-Shaped Porous Metal Element?

 

The round format is useful when the filtration element must fit a compact housing, valve, regulator, sensor, nozzle, laboratory fixture, or OEM assembly. A porous metal disc can provide a rigid form and can be engineered around the mechanical and thermal conditions of the assembly.

For reusable systems, sintered stainless steel mesh discs can also be washable and reusable. This makes them suitable where the element is expected to remain in service through repeated cleaning cycles. The final choice should consider retained contaminants, cleaning method, material compatibility, flow requirement, and installation arrangement.

2. Common Sintered Metal Filter Disc Forms

Disc Form
Typical Construction
Common Selection Reason
Powder-Sintered Disc Porous metal produced from compacted and sintered powder Rigid porous element with application-specific filtration
Sintered Mesh Disc Layered stainless steel wire mesh sintered into one media structure Controlled layered construction and reusable service
Washer-Shaped Disc Round disc with a center hole Mounting around a shaft, fastener, or flow passage
Thick Porous Disc Increased thickness with a porous body Mechanical support or additional media depth

Disc geometry can also be customized with stepped edges, shoulders, grooves, or other locating features. NAVI Titanium supports customized Sintered Metal Filter Discs based on customer drawings, samples, or specified dimensions, allowing these geometric details to be matched to different assembly requirements. For replacement parts, a drawing, old-part photograph, measured dimensions, or physical sample can help define the required geometry.

3. Materials and Filtration Grades

 

Sintered metal filter disc material selection should start with the working medium and operating environment rather than disc diameter alone. Stainless steel is widely used for gas, liquid, oil, chemical, and process filtration. Bronze is commonly considered for pneumatic, air, gas, oil, venting, and compact filtration applications. Sintered stainless steel mesh provides another option where a layered and reusable structure is preferred.

The manufacturer currently lists approximately 0.1–80 μm across available powder-sintered grades. Standard five-layer 316L sintered wire mesh is listed at approximately 1–100 μm. These figures are reference ranges rather than a guarantee for every finished disc.

Selection Factor
What to Confirm
Why It Matters
Material 304/316L stainless steel, bronze, or other qualified option Must suit the working medium and temperature
Media structure Powder-sintered or sintered mesh Affects flow and filtration behavior
Filtration grade Pore or micron requirement Sets the intended filtration level
Thickness Finished disc thickness Affects resistance and stiffness
Effective area Exposed porous area after sealing Determines actual flow area
Operating flow Gas or liquid flow rate Needed for pressure-drop evaluation

A micron value alone does not automatically guarantee a specific particle-removal efficiency. NAVI Titanium can work with customers to define the required filtration performance based on particle size, target efficiency, operating flow or face velocity, and test method, helping establish a clearer specification before production. If a defined removal percentage is required, specify particle size, target efficiency, operating flow or face velocity, and test method.

 

4. How to Select the Right Disc

 

Start with the application and move toward detailed geometry. First identify the medium: air, gas, liquid, oil, or another process fluid. Then define temperature, line pressure, flow rate, contamination level, and allowable clean-filter differential pressure.

Next, choose the media structure and material. Confirm outside diameter, thickness, center-hole diameter if needed, edge geometry, tolerance, sealing method, and exposed filtration area. These dimensions can change usable porous area and restriction.

For pressure-drop-sensitive applications, clean-filter differential pressure should be evaluated at the required operating flow. A very fine filtration grade may be unsuitable if the available disc area is too small for the required throughput.

 

5. Where Are Sintered Metal Filter Discs Used?

 

Sintered metal filter discs are suited to compact filtration and protection points across industrial equipment.

Application
Typical Function
Key Review Point
Gas & compressed air Particle control, venting, compact filtration Flow and pressure drop
Liquid & oil circuits Process filtration and component protection Viscosity, contamination, compatibility
Valves & regulators Protect small flow passages Disc fit and sealing
Sensors & instruments Prevent contamination of sensitive passages Filtration level and exposed area
Laboratory equipment Sample conditioning and pilot filtration Small dimensions and reproducibility
Pneumatic assemblies Airflow and venting Material and cleaning needs
OEM equipment Replacement or integrated porous element Drawing, sample, installation layout

Because the disc can be produced in small custom sizes, it is useful where a standard cartridge or large housing is impractical. The referenced manufacturer specifically identifies gas and compressed air, liquid and oil circuits, valves, regulators, sensors, laboratory equipment, pneumatic assemblies, and custom OEM assemblies as application areas.

6. Powder-Sintered Disc vs. Sintered Mesh Disc

 

The two constructions should not be treated as interchangeable.

Comparison
Powder-Sintered Disc
Sintered Mesh Disc
Basic construction Porous metal produced from compacted and sintered powder Multiple layers of stainless steel wire mesh
Typical reference range Approx. 0.1–80 μm Approx. 1–100 μm for standard five-layer 316L
Geometry Custom diameter, thickness and center hole Custom laser-cut diameter and center hole
Cleaning Depends on material and contamination Washable/reusable structures available
Main advantage Rigid porous body Layered media with reusable construction

The correct choice depends on the complete application rather than the nominal micron number. NAVI Titanium can help customers evaluate the application requirements and select a suitable media construction based on filtration needs, flow characteristics, material requirements, and operating conditions. The source page also emphasizes that powder-sintered and sintered-mesh constructions should be specified separately because their media structures and flow characteristics differ.

 

7. Customization for OEM and Replacement Parts

 

Custom sintered metal filter disc manufacturing is valuable when the filter must match an existing assembly. Typical customization includes outer diameter, thickness, center hole, filtration requirement, edge profile, material, media structure, sealing area, and installation method.

For OEM projects, the complete assembly drawing is preferable when the disc is welded, framed, clamped, or retained inside another part. For replacement projects, an old component, sample photograph, dimensional sketch, or physical sample can provide a starting point for feasibility review.

The buyer-oriented approach used by specialized electrochemical suppliers is also useful here: define the actual operating environment and installation requirements before finalizing geometry. HELE Titanium's MMO rod anode guide, for example, asks buyers to consider application, environment, active area, current density, connection, installation, and documentation before selecting an electrode configuration. The same logic can be applied to filtration components.

 

8. Quality Control and Supplier Evaluation

 

For industrial buyers, quality is not only about visual appearance. A supplier should be able to review material, dimensions, media structure, filtration requirement, and finished installation conditions. NAVI Titanium follows a specification-focused approach, reviewing these key requirements with customers before production to help ensure that the Sintered Metal Filter Disc matches the intended application and assembly conditions.

Useful records may include material documentation, dimensional inspection, visual inspection, filtration or performance testing when specified, and order traceability. NAVI Titanium can support customers with corresponding inspection and documentation requirements, while testing arrangements can be defined according to the agreed technical specification. If particle-removal efficiency is part of acceptance, the test particle size, target removal percentage, operating flow, and test standard should be agreed before production.

A capable supplier should also distinguish between a pore-size rating and a tested filtration-efficiency claim. This helps prevent misunderstandings during OEM qualification and purchasing. The product source specifically notes that micron or pore values do not by themselves establish finished particle-removal efficiency. NAVI Titanium can help clarify the difference between nominal filtration ratings and performance-based requirements during specification review, giving OEM and industrial buyers a clearer basis for product evaluation and acceptance.
