Clear filters
Specify the working disc, not just its diameter
The seating land and centre hole determine how much area is available for flow.
Outside and inside diameters
For annular discs, specify OD, ID and concentricity. Include all locating holes and tabs.
Aperture and wire
For square weave, aperture a = 25.4 / N - d, with a and d in mm and N in openings per inch.
Edge condition
Choose plain-cut edges for captured seats or a rim where handling and wire retention require it.
Finished thickness
State the complete thickness of mesh layers and any rim, not just the nominal wire diameter.
Construction
Cut edge, seating land and support
- Rims occupy areaA metal rim protects the edge but reduces active filtration diameter. Locate the rim outside the required flow opening wherever the seat allows.
- Unsupported spanA flat fine-mesh disc needs backing when pressure can bow it into the outlet. A holder face or coarse screen may provide this support.
- Annular screensThe inner cut edge needs the same retention and sealing attention as the outside edge; an OD-only drawing is incomplete.

Filter discs and cut screens
Applications
Small flat screens suit compact flow passages.
Inline holders
Removable mesh inserts for liquid passages and inspection ports.
Valve and nozzle protection
Screens intercept debris before narrow flow restrictions.
Extrusion equipment
Single discs serve as defined layers in larger screen packs.
Disc inspection focuses on the perimeter
A correctly specified cloth can still leak around an undersized or damaged edge.
01OutlineMeasure OD, ID, holes and profile against the seating geometry.
02Cut and rimCheck loose wires, burrs, rim closure and layer alignment.
03Mesh identityCheck the weave, wire diameter and opening in both cloth directions.

Questions before ordering
Is 100 mesh equal to 100 microns?
No. With 0.10 mm wire, 100 openings per inch gives a nominal square aperture of 0.154 mm, or 154 µm. A different wire diameter produces a different aperture.
When is a rim useful?
Use a rim when screens are repeatedly handled, several layers must remain registered, or cut wires need containment. A rim must still fit the holder thickness and sealing land.
How is a disc edge prevented from bypassing?
The perimeter must match its seat and keep the filtering layer captured. Specify OD, flatness, gasket or rim geometry and the clamping load or housing detail.
