what could be delivered under naturally aspirated
On some engines, an air-to-air aftercooler cools the
turbocharger compressor discharge air by routing it
Under suction generated by the engine, unfiltered air flows
through air inlet tube (A) and is forced into a high-speed
centrifugal motion by tilted fins in the element. By this
circulating action most of the dust and dirt particles are
separated from the air and collected in the dust unloading
The remaining dirt is removed as the air flows through the
primary element (C) and the secondary (safety) filter (B)
before being drawn into the engine.
The secondary (safety) filter ensures that should primary
element fail, no unfiltered air is drawn into the engine.
