“IBFs effectively clean the air used during the combustion process. The cleaner the air, the less damage will occur to the engine during combustion. On top of erosion, we also have the reduction of corrosion and fouling,” says Bohm.
“Unlike particle separators, which only stop larger particles and FOD, IBFs also stop smaller particles and salt nuclei. In addition, IBFs are passive devices in that they create a barrier between the engine and the outside environment,
particle separators are active devices that require power to function.”
