In an air filter assembly a non-metallic air filter media is clamped between a pair of opposed metal end flanges, one of which is mounted by a threaded mounting rod in alignment with an opening through a horizontal panel. A metal sleeve integral with one of the end flanges stiffens the assembly and prevents the filter media from collapsing. The air filter assembly is used with numerous similar air filter assemblies to filter inlet combustion air for large gas turbine engines.
