02.1 / FILTER DISCS & EDGED SCREENS
Filter Discs & Edged Screens
Circular, ring and shaped screens intercept particles inside equipment. Confirm media, layers and edges together with filtration needs and installation.
Start with a photo or drawing, even if some specifications are still unknown.

- Common materials
- SS304, SS316 / SS316L; confirm the alloy against the process medium.
- Construction options
- Single-layer cuts, multilayer spot welds or metal edging; confirm support layers against differential pressure.
- Dimensions
- Screen dimensions: outside diameter A, inside diameter B for rings, total thickness t.
- Filtration requirements
- Mesh count, wire diameter or target filtration rating; confirm the rating definition and verification method.
Dimensions to discuss
Not to scale. Letters identify dimensions to be confirmed.

Common structures & selection priorities
- Construction options
- Single-layer cuts, multilayer spot welds or metal edging; confirm support layers against differential pressure.

- Screen dimensions: outside diameter A, inside diameter B for rings, total thickness t.
- Key considerations
- Edging protects the perimeter and assists fitting. Plain cuts need suitable clamping and sealing in the equipment. Confirm the installation and edge requirements.
Filtration knowledge & FAQs
How do I choose edged or plain screens?
Edging protects the perimeter and assists fitting. Plain cuts need suitable clamping and sealing in the equipment. Confirm the installation and edge requirements.
Is mesh count the same as filtration rating?
Mesh count describes openings per inch. Aperture also depends on wire diameter and weave; mesh count alone does not establish particle retention.
How do operating pressure and differential pressure differ?
Operating pressure is the system pressure. Differential pressure is the pressure difference across the element. Confirm operating pressure, clean pressure drop and maximum allowable differential pressure.
How are cleaning and maintenance determined?
Confirm cleaning methods, backwash conditions and replacement criteria against the equipment instructions and process medium, rather than appearance alone.
