A filter cassette (1) for removing particles from an air stream, in particular from a gas stream entering a gas turbine, has an upstream end (14) and a downstream end (16) and comprises a mounting frame to which a filter media (4) is fitted and which has a mounting face (5) adapted for mounting the filter cassette to an opening (15) of a partition (6). The mounting face is positioned between the filter cassette's upstream and downstream ends at a first distance (Dup) from said upstream end (14) and a second distance (Ddown) from said downstream end (16). The first and second distances each amount to more than 10% of an overall length of the filter cassette. Preferably, the mounting face (5) is positioned centrally between the upstream and downstream ends (14, 16), approximately in a barycenter line of the filter cassette (1). The filter cassette thus extends to both sides of the partition opening (15). Filter surface area is increased and torque induced by the filter cassette (1) into the partition (6) is reduced. |
