Abstract
An inlet air filter arrangement for a gas turbine or a combustion turbine includes a housing with an inlet side and an outlet side separated by a planar tubesheet including multiple tubesheet openings. Each multiple cylindrical filter cartridge includes a symmetry axis, an open end, and a closed end. A connection assembly for each of the multiple cylindrical filter cartridges seals the open end of the cylindrical filter cartridge to the tubesheet around one of the tubesheet openings. The connection assembly includes a mainly cylindrical guide sleeve including a symmetry axis, a shell with a cylindrical external surface, an inner end attached around the tubesheet opening and an outer end at the inlet side of the housing. The shell is provided with at least two slots extending mainly helically from the outer end towards the inner end. A collar attaches to the open end of the cylindrical filter cartridge.
