UH-1 and AH-1G Helicopters have a particle separator installed that is designed to remove small particles from the engine inlet air. It does not remove, or protect against foreign object damage FOD caused by, larger objects such as nuts, bolts, Dzus fasteners, lockwire, ect. Because of the high rate of FOD to engines, the engine manufacturer developed an inlet screen for the separator.
