Construction
How sintered elements are made
- Sintered meshBonded wire layers stabilize geometry and support one another. Preserve layer orientation and weldable margins when fabricating an element.
- Sintered-powder mediaInterconnected pores form between the sintered powder particles. Porosity and wall thickness influence pressure loss during normal flow. They also affect the removal of deposits during cleaning.
- Fiber feltMetal fibers form a depth structure that can provide useful area in pleated elements. Dirt holding and cleaning require a different assessment from square-opening mesh.
- Cutting and joiningReserve solid joining zones and support positions before fabricating discs or welded cartridges. Keep media orientation, active area and end interfaces on the finished drawing.

Read the porous structure before choosing the shape
Sintered mesh bonds woven layers into a stable laminate; fiber felt uses a network of fine metal fibers; sintered-powder media forms interconnected pores between bonded particles. These structures have different pore paths and support needs even when their grade labels use the same unit.
Choose the sheet or felt product for further fabrication and the disc or cartridge product for an installed component. The structure comparison guide explains the three media families, while the performance downloads retain each series with its own thickness and test conditions.
From a porous sheet to a sealed filter element
Disc clamping lands, cartridge weld bands and end connections are designed around the filtering layer. Keep active area separate from joined or covered surfaces. The support carries the normal differential-pressure load and the load during reverse cleaning.
Record the assembled flow path, joining method and seal location with the media grade. After cleaning, inspect the filtering surface, supports and joints against the original acceptance criteria. This connects media selection to the actual reusable component.

What we need to quote a sintered element
A sintered element is specified by rating, structure and allowable pressure drop together — porosity alone does not define it.
Media type and rating basis
Distinguishes mesh, powder and fiber structures
Permeability or pressure-drop target
Supports flow comparison
Thickness and finished form
Defines fabrication route
Differential pressure and direction
Guides support and joint design

Compare data on the same test basis
| Parameter | Record with the value | Comparison basis | Component check |
|---|---|---|---|
| Filtration grade | Test method and medium | Same retention definition | Filter-layer designation |
| Permeability | Fluid, pressure difference and thickness | Same test conditions | Active flow area |
| Area | Exposed face, weld bands and covered zones | Installed rather than blank area | Clamping and support |
| Cleaning | Direction, method and acceptance criteria | Same fouling and cleaning sequence | Media, joints and seals |

Applications
Sintered elements combine a defined pore structure with a metal support system for process filtration, reusable cartridges and flow distribution. Material, construction and operating conditions are specified together.
Reusable elements
Rigid discs and tubes for process housings.
Pleated elements
Fiber felt or suitable laminate for increased filtration area.
Diffusion
Porous parts for flow distribution require permeability specifications, not only particle ratings.
Match inspection to the porous structure
Match dimensional inspection, pore-structure checks and the specified retention test to the finished component.
Construction
Verify media grade, thickness, layer orientation and alloy.
Integrity
Use the specified integrity or bubble test where applicable.
Finished part
Inspect welded and machined edges that can introduce bypass.
Cleaning acceptance
Compare the cleaned surface and flow response with the accepted initial condition; check support, seams and seals as parts of the same assembly.
Documented product examples

Questions before ordering
What does the bubble test measure?
The specified bubble test checks the permeable structure under defined wetting and pressure conditions. Record the test liquid, pressure and acceptance criterion with the result; particle-retention testing establishes the filtration performance.
How is a cleaned element released for reuse?
Inspect the filtering surface, supports, joints and seals, then compare the specified flow or integrity result with the accepted initial condition. Release the element when it meets the defined cleanliness and structural criteria.
How is a nominal micron grade specified?
State the particle or pore test, test fluid, flow conditions and acceptance criterion with the grade. Compare sintered mesh, metal fiber felt and sintered-powder media on that stated basis.
How are permeability values compared?
Keep test fluid, differential pressure and specimen thickness with every value. Compare matching conditions within a defined media series, then size the exposed area in the component.
How does a sheet become a cartridge?
The drawing defines orientation, formed wall, joining bands, support and end connection. The media grade remains linked to that construction through fabrication and cleaning.
