Wedge wire slot selection
Set slot width, profile and support arrangement for the direction of flow and solids being retained.

Match slot to solids
A slot controls the smallest passable particle in one direction, while particle shape and orientation affect actual passage. Provide representative solids or an application test for critical retention.
Size the supporting structure
Profile wire size, support pitch and cylinder or panel span determine mechanical behaviour. Confirm operating and reverse-flow differential pressures separately.
Plan cleaning direction
The open side of a wedge profile can help release captured solids in a specified flow orientation. Draw both service and cleaning flow arrows to avoid an inverted assembly.
Specification checklist
| Parameter | Specification / example | Why it matters |
|---|---|---|
| Slot width | Nominal plus tolerance | Retention and throughput |
| Profile/support | Wire and rod geometry | Strength and open area |
| Flow direction | Service and backwash arrows | Cleaning and installation |
Practical questions
What should I send when requesting wedge wire slot selection?
Send the drawing or installed-part dimensions, the media or opening requirement, process conditions, quantity and the acceptance test you need.
Can a sample replace a drawing?
A physical sample is useful for fit and construction review. Dimensions, material grade and performance requirements still need written confirmation before production.
