Wedge wire screen panels — Product view
Parallel profile wires form the working face and are welded to transverse support members. The broad wire faces carry the material being screened. The passages widen behind the narrow entrance, helping particles that enter the slot pass through the screen. Slot direction and working face are defined with the feed and discharge arrangement.
Surface-wire width determines the amount of metal between adjacent slots. Wire height contributes to the section geometry. Support profiles carry the welded working surface across the mounting span. Choose the surface and support sections separately from the tables, then set their spacing for the panel size, attachment points and service loads.
For parallel profile wires, the exposed-face open fraction is slot width divided by slot width plus surface-wire face width. The comparison table shows calculated percentages for three face widths. Frames, supports and mounting features occupy additional area in the installed panel. The panel drawing identifies active screening area and overall footprint separately.
Specify overall length and width, active area, frame section, fixing holes and clamping faces. Include feed direction, fluid, solids loading and vibration or impact loads. Cleaning uses surface rinsing, brushing or reverse flow matched to the installed arrangement. Inspection checks working-face slot width, profile sections, support spacing, flatness, welds and mounting dimensions.
The broad face of each profile wire forms the screening surface. The narrow section behind it creates a widening passage through the panel. The drawing identifies the working face, slot direction and flow arrow; transverse supports lie on the back. Resistance-welded intersections connect each surface wire to the support members so the panel acts as one rigid screen.
An unframed panel fits into a supporting seat; an edged panel protects the cut wire ends; a perimeter frame provides the fastening interface. Support rods, crossmembers and the equipment seat carry the hydraulic and solids load. The frame drawing fixes the clear span, bearing width, mounting-hole pattern and edge clearance independently of the slot.
Specify the alloy separately for profile wires, support rods, edge strips, frame and mounting parts. Their compatibility covers the process liquid and cleaning chemistry. Inspection combines slot measurements across the working face, wire-profile identification, support pitch, panel flatness, squareness, weld attachment and mounting dimensions. The existing profile and open-area tables describe the surface geometry; the frame and supporting members complete the installed design.
A flat wedge-wire panel is defined by its active length and width, perimeter and back supports. The profile-wire direction sets the slot direction; the support members locate the working plane relative to the machine seats. Draw the exposed screen area separately from frame and clamping lands.
A sieve bend is a separate curved construction with radius, arc angle and a feed tangent. When moving from a flat panel to a curved screen, the machine drawing must include those curved interfaces. For a flat-panel replacement, preserve the existing support contact, working-face direction and access for cleaning.
V-wire and continuous-slot screen describe the welded wedge-wire construction. Johnson Screens is a manufacturer’s brand name that also appears in equipment specifications as Johnson screen. A Kaifil replacement panel is defined by its working-face slot, paired profile dimensions, support arrangement and mounting datums. Flat panels, curved sieve bends and cylindrical well screens each retain their own installation geometry.
Width is measured across the working face; height is the depth of the profile.

|---|---|---|
| 0.8 | 1.9 | 6.5 |
| 1.2 | 2.5 | 10 |

Open area = slot / (slot + wire face width) × 100%. These percentages describe the exposed wire-and-slot surface.

Continuous slots drain liquid while the working surface supports the retained solids.
Slot width and travel direction define the screening surface for separation equipment.
Supported panels retain process media while maintaining a drainage path.
Panel outline, fixing points, profiles and slot direction match the existing equipment.
Measure the narrow opening between adjacent profile wires at the working face.
Exposed-face open area equals slot width divided by slot width plus surface-wire face width, multiplied by 100%. Installed free area also accounts for supports and frames.
Surface-wire and support sections are selected independently, then combined with the required spacing and panel layout.
