Powder-Sintered and Sintered Mesh Discs Use Different Media Structures
The term “sintered filter disc” can describe more than one metal filtration structure. A rigid powder-sintered disc and a disc cut from sintered stainless steel wire mesh have different construction and should be specified separately.
If the existing filter structure is unknown, send photographs, dimensions, drawings or a physical sample for technical evaluation.
- Powder-sintered stainless steel and bronze disc structures
- Sintered stainless steel wire mesh laser-cut into disc form
- Custom diameter, thickness, center hole and edge geometry
- Flow and pressure-drop review for restriction-sensitive applications
- Drawing and sample review for replacement components
Technical Reference for Sintered Metal Filter Discs
Filtration grade and thickness depend on the selected disc structure. Powder-sintered metal and sintered wire mesh should be evaluated using their own material and construction data.
Approx. 0.1–80 μm Available Grades
Powder-sintered metal filters are available across approximately 0.1 to 80 μm. The suitable range for a filter disc depends on material, diameter, thickness and porous configuration.
Laser-Cut, Washable & Reusable
Sintered stainless steel mesh can be laser-cut into disc form and is suitable for washable and reusable industrial filtration structures.
Approx. 1–100 μm Mesh Grades
When the disc uses standard five-layer 316L sintered wire mesh, filtration grades are available from approximately 1 to 100 μm. Other mesh constructions should be specified separately.

Micron Rating Is Not Automatically a Particle-Efficiency Guarantee
A pore or micron value describes the selected porous medium or filtration grade. It does not automatically establish particle-removal efficiency at a particular particle size.
Finished filtration performance depends on media structure, disc thickness, effective filtration area, sealing, support, flow conditions and the test method.
If the application requires a defined efficiency, such as a specified removal percentage at 0.1 μm, 0.3 μm or another particle size, provide the particle size, target efficiency, operating airflow or face velocity, and the required test standard.
Diameter, Thickness, Center Hole and Installation Details
Small changes in disc geometry can affect mechanical fit, sealing and effective porous area. Drawings should identify the dimensions that control installation and filtration area.
Outer Diameter
Specify finished outside diameter, dimensional tolerance and whether the disc is press-fit, clamped or located inside another component.
Disc Thickness
Thickness affects mechanical stiffness, porous resistance and available manufacturing structures. It should be evaluated with the selected media.
Center Hole / Inner Diameter
Washer-style discs should specify center-hole diameter, tolerance, concentricity and the function of the center opening.
Edge & Mounting Geometry
Flat edges, steps, shoulders, grooves or other locating features should be included in the drawing.
Sealing Area
If part of the disc is covered by a gasket, clamp or metal retainer, identify the actual exposed porous area available for flow.
Finished Assembly
If the disc is welded, framed or assembled into a holder, provide the complete assembly drawing together with the disc dimensions.

What filtration range is available for powder-sintered filter discs?
Powder-sintered metal filters are available across approximately 0.1 to 80 μm. The suitable range for a specific disc depends on material, thickness, diameter and porous structure.
What filtration grades are available for sintered mesh filter discs?
When a disc uses standard five-layer 316L sintered wire mesh, filtration grades are available from approximately 1 to 100 μm. Other mesh constructions require separate specification.
Can sintered stainless steel mesh discs be cleaned and reused?
Yes. Sintered stainless steel mesh is used in washable and reusable industrial filtration structures. The cleaning method depends on contaminants and the finished assembly.
Can METAVOX manufacture washer-shaped discs with a center hole?
Yes. Center-hole and washer-style components can be manufactured according to outside diameter, inside diameter, thickness, tolerance and mounting requirements.
Does a 0.1 μm or 1 μm rating guarantee a specific particle-removal efficiency?
No. A micron or pore grade does not by itself define finished particle-removal efficiency. If efficiency is an acceptance criterion, provide the particle size, target removal percentage, operating flow and test standard.
Why is airflow or liquid flow needed for a small filter disc?
Pressure drop depends on both the porous medium and the flow through the available filtration area. Disc diameter, exposed area, thickness and operating flow all affect finished restriction.
What is the difference between a filter disc and a filter plate?
A filter disc is primarily round or washer-shaped. A filter plate or porous sheet is used for rectangular, square or other larger flat geometries.
Can you manufacture replacement filter discs from a sample?
Yes. Replacement components can be evaluated from drawings, old-part photographs, dimensions, installation information or physical samples before manufacturing feasibility is confirmed.
