The description of turbo compressor impeller:

The turbo compressor impeller (compressor wheel) is of aluminium alloy or the more expensive titanium. Manufactured from a single casting, it is located on the rotor shaft by splines.

Aluminium impellers have a limited life, due to creep, which is dictated by the final air temperature. Often the temperature of air leaving the impeller can be as high as 200°C.

The life of the impeller under these circumstances may be limited to about 70000 hours. To extend the life, air temperatures must be reduced. One way of achieving this is to draw the air from outside where the ambient air temperature is below that of the engine room.

Efficient filtration and separation to remove water droplets is essential and the impeller will have to be coated to prevent corrosion accelerated by the possible presence of salt water.
