A filtering chamber for a gas turbine having a combustor, compressor and air inlet duct, and a corresponding maintenance method is described. The filtering chamber includes a first chamber in an inlet plenum; a second chamber in the inlet plenum; and an air bypass mechanism configured to reduce a pressure difference across a final filter that separates the first chamber from the second chamber.

1. A filtering chamber configured to provide air to an inlet of a compressor, the filtering chamber comprising: a first chamber in an inlet plenum, the first chamber comprising a first door and a prefilter installed in an intake port, the intake port being connected to an exterior of the filtering chamber;a second chamber in the inlet plenum, the second chamber being separated by a intermediate filter and a final filter from the first chamber, and comprising a second door; andan air bypass mechanism configured to reduce a pressure difference across the final filter, the pressure difference being generated by a suction of the compressor when the compressor is operating,wherein the intermediate filter directly faces the final filter and a guard filter is installed downstream from the final filter. 2. The filtering chamber of claim 1, wherein the air bypass mechanism comprises: a first bypass port connecting the first chamber and the second chamber to each other. 3. The filtering chamber of claim 2, wherein an area of the first bypass port is between 1 and 2 m2. 4. The filtering chamber of claim 3, wherein the final filter cannot be extracted when the compressor is working and the first bypass port is open. 5. The filtering chamber of claim 2, wherein the air bypass mechanism further comprises: a second bypass port connecting the second chamber to the exterior of the filtering chamber. 6. The filtering chamber of claim 5, wherein an area of the second bypass port is larger than an area of the first bypass port. 7. A gas turbine system, comprising: a compressor configured to compress air;a combustor fluidly connected to the compressor and configured to receive the compressed air;a turbine connected to the combustor and configured to receive hot gases from the combustor for producing mechanical energy; andthe filtering chamber according to claim 1, wherein the filtering chamber is connected to an inlet of the compressor, and is configured to clean the air provided to the compressor. 8. A method of operating a filtering chamber configured to provide cleaned air to a compressor, the method comprising: removing or opening a first bypass port between a first chamber and a second chamber in the filtering chamber to reduce a pressure across a final filter, the final filter dividing the filtering chamber into the first chamber and the second chamber;removing or opening a second bypass port between the second chamber and an exterior of the filtering chamber;replacing the final filter;closing the second bypass port; andclosing the first bypass port,wherein the above steps take place while the compressor is online. 9. The method of claim 8, wherein the filtering chamber comprises an intermediate filter and a final filter dividing the filtering chamber into the first chamber and the second chamber, the method further comprising: opening a first door, entering the first chamber;removing the intermediate filter to reveal the final filter;opening a second door, entering the second chamber, and closing or leave it open the second door;opening the second door, exiting the second chamber, and closing the second door;reinstalling or replacing the intermediate filter to cover the replacement final filter; andopening the first door, exiting the first chamber, and closing the first door,wherein the above steps take place while the compressor is online. 10. The method of claim 8, wherein the filtering chamber comprises an intermediate filter and a final filter dividing the filtering chamber into the first chamber and the second chamber, the method further comprising: before removing or opening a first bypass port: opening a first door, entering the first chamber; andremoving the intermediate filter to reveal the final filter;after opening the second bypass port: opening a second door, entering the second chamber, and closing or leave it open the second door;after replacing the final filter: opening the second door, exiting the second chamber, and closing the second door; andafter closing the first bypass port: reinstalling or replacing the intermediate filter to cover the replacement final filter; andopening the first door, exiting the first chamber, and closing the first door,wherein the above steps take place while the compressor is online. 11. A filtering chamber configured to provide air to an inlet of a compressor, the filtering chamber comprising: a first chamber comprising a prefilter and an intermediate filter;a second chamber fluidly connected to the first chamber, and comprising a guard filter;a final filter provided downstream the intermediate filter; anda blade provided in the second chamber, and configured to rotate about a horizontal axis or a vertical axis such that a first row or a first column of cells of the final filter are sealed between a frame and the blade,wherein the blade is configured to reduce a pressure difference acting on the first row or the first column of cells when the filtering chamber is active.
