Gas turbine inlet filter with replaceable media cartridges
First Claim
1. A filter arrangement for a system within which fluid is filtered, the system has a portion with an aperture into which the filter arrangement is located for filtering fluid from a dirty side and to a clean side as the fluid flows through the filter arrangement, the filter arrangement including:
- a frame including;
an outer periphery that has a shape that is complementary to a shape of the aperture for location of the filter arrangement therein; and
a plurality of filter cartridge seat slots arranged in V-shaped pairs, each filter cartridge seat slot providing a sub-aperture through the frame for flow proceeding from the dirty side to the clean side, each filter cartridge seat slot for removably receiving a respective filter cartridge in a direction transverse to the flow proceeding through the sub-aperture;
a plurality of filter cartridges, each filter cartridge being removably located within a respective filter cartridge seat slot of the frame, each filter cartridge including filter media that allows flow therethrough from the clean side to the dirty side while stopping flow of particulate matter;
a non-permanent sealing arrangement between the filter cartridges and the frame so that flow does not by-pass the filter media, the non-permanent arrangement permitting removal of the filter cartridges from the frame and replacement with new filter cartridge upon the frame;
wherein the non-permanent sealing arrangement includes seals that are located between the filter media of the filter cartridges and portions of the frame;
wherein the filter cartridges include filter media in a pleated configuration and glue lines extending to retain the media in the pleated configuration; and
wherein the seals engage against the pleated configuration of the media.

Abstract
A filter arrangement for a system within which fluid is filtered and an associated method of providing the arrangement. A frame of the arrangement includes an outer periphery shape that is complementary to a shape for location of the filter arrangement therein and a plurality of filter cartridge seat slots arranged in V-shaped pairs. Each filter cartridge seat slot provides a sub-aperture for removably receiving a respective filter cartridge in a direction transverse to the flow proceeding through the sub-aperture. The filter arrangement includes a plurality of filter cartridges that are removably located within respective filter cartridge seat slots. The filter arrangement includes a non-permanent sealing arrangement between the filter cartridges and the frame so that flow does not by-pass filter media. The non-permanent arrangement permits removal of the filter cartridges from the frame and replacement with new filter cartridges upon the frame.
