Recommended Gas Turbine Inlet Air Filtration System
- INLET WEATHER HOOD. (inlet velocity < 3.5 m/s for rain. < 1.7 m/s
for snow)
- INLET BIRD SCREEN
- ANTI- ICING, if climatic conditions warrant
- COALESCER DEMISTER
- PRE FILTER. (minimum 85% ASHRAE 52.1 arrestance and minimum 2,000
grams SAE-Fine dust holding capacity)
- FINAL STAGE. Fully potted hydrophobic high efficiency barrier air
filter. ( 95% ASHRAE 52.1 Dust Spot Efficiency. Filter bank sloped and
provided with drain shelves and down drains to facilitate drainage of
deliquesed droplets).
- INLET AIR COOLING. Evaporative cooling or chilled water coils, if
climatic conditions warrant
