Abstract: A filter screen includes a plate body with an upstream surface, an opposed downstream surface, and an array of apertures extending between the upstream surface and the downstream surface. A polytetrafluoroethylene-based layer overlays the upstream surface between apertures of the aperture array, the polytetrafluorethylene-based layer being conformally disposed over the upstream surface of the plate body and spanning the upstream surface between the apertures of the aperture array to slow deposition of carbonaceous deposits on the filter screen.
