Zusammenfassung:	A rotating filter screen assembly is provided for filtering debris from cooling and combustion air provided to an engine system having an engine fan adapted to draw air through the filter screen assembly. The filter screen assembly includes a rotating filter screen having an upstream side and a downstream side. The filter screen is adapted to collect debris on the upstream side from air passing through the filter screen. A stationary cleaning chamber is mounted in the filter screen assembly and has an open face adjacent the upstream side of the filter screen. A vacuum source is connected to the cleaning chamber and is adapted to remove collected debris from the upstream side of the filter screen as the filter screen rotates relative to the cleaning chamber. An aerodynamic baffle plate is offset from the downstream side of the filter screen to divert air flow toward the downstream side of the filter screen so as to create an area of high pressure air at the open face of the cleaning chamber.
