Contaminant and medium
Specify the particles to remove, viscosity, flow rate and allowable pressure drop. A woven screen aperture can be measured geometrically; a filtration rating still needs the agreed test basis.
Fit and cleaning
The filter disc or basket must seat without bypass around its edge. Consider solvent exposure, cleaning procedure, change frequency and whether a disposable screen pack or reusable rigid element is more appropriate.
Information for quotation
Provide process and cleaning chemistry, the holder or basket drawing, mesh specification or target opening, edge construction, material grade, quantity and any packaging requirement for finished screens.
Design review
A cut disc, removable basket and cylinder protect different points in a coating or ink line. Compare the contaminant and pigment distribution, viscosity, solvent system, flow and cleaning frequency. The part edge must seal in its holder; otherwise fluid can bypass even a suitably fine mesh. Confirm compatibility of welds and seals with both product and wash solvent.
Inspection and acceptance
Send a holder drawing, the current part or sample, target opening or test-defined rating, material and finish. Record the pressure drop and change or cleaning interval during a line trial. The page does not claim that one mesh opening is appropriate for all coatings, inks or downstream pump arrangements.
