HIGH FILTERING PERFORMANCEFOR GAS TURBINES AND COMPRESSORS DEPTH-LOADING FILTER CARTRIDGES - GTG SERIES The application Depth-loading filter cartridges of the GTG series are used in supply air filtration systems for gas turbines and turbo compressors.
The concept GTG depth-loading cartridges with their optimum pressure drop characteristics and maximized useful lifetimes, significantly enhance the cost efficiency of turbomachinery systems. They are particularly successful whenever the cleaning of surface filter cartridges does not produce any effective reduction in pressure drop, because the dust concentrations are too low and / or the dusts concerned are too sticky. The characteristics and the benefits • Innovative high strength synthetic micro-glassfiber nonwoven with water repellent coating and uniform pleat spacing for maximum dust holding capacity. • The filter medium offers excellent initial efficiency (of Filter class F9 level), high dust holding capacity, low pressure drop and high cost efficiency. This makes the GTG cartridges particularly suitable for locations with high fine dust concentrations in the ambient air. • GTG cartridges have been optimized in terms of filtering area, pleat depth and number of pleats which means the active filtering area remains completely effective over its entire operating lifetime. • The pleat pack, plus the inner and outer support cages are cast into the steel-galvanized or stainless steel end caps in a leakproof configuration. The foamed-on EPDM gasket ensures optimum sealing against the mounting plate. • GTG depth-loading cartridge filters can be obtained in a variety of other dimensions and designs. • The Freudenberg Filtration Technologies product range comprises other cartridge solutions for pulse applications.
