| Cylinder or tube | A simple cylindrical screen or support is needed | Diameter, seam, ends, media and pressure direction |
| Disc | A flat screen fits a compact seat or cavity | Outline, media, edge, thickness and support |
| Screen pack | Several layers must install as one controlled stack | Layer order, joining, cavity and pressure trend |
| Basket | Solids must collect in a removable body | Housing seat, area, support, handle and maintenance access |
| Cone | A shaped pipeline screen provides equipment protection | Flange, orientation, length, aperture and pressure direction |
