DESCRIPTION: Ready-to-install SHIELDSCREEN filters incorporate highly effective, integral EMI frame gasketing of monel with an optional neoprene sponge weather seal. Filtering is provided by several layers of woven wire mesh behind a retaining grille. The mesh layers are nested in “hills and valleys” of decreasing height to separate layers and increase dust holding capacity. The mesh filter may be used dry, or wet with viscous oil coating, which improves adhesion of dust particles to the filtering material. SHIELDSCREEN frames are of the same EMI gasketed, extruded aluminum construction as SHIELD CELL aluminum honeycomb panels. Because they are complete assemblies, removal for periodic cleaning is simple. Dry filters are cleaned by vacuuming from the intake side (which can be accomplished in place), or in detergent solution. Oil impregnated filters require removal and cleaning in detergent solution. Re-oiling is required after cleaning with detergent.
