[Vwdiesel] Clogging

Do the larger engines have inertial separators?

The Cessna 208B with a PT6A114A turbine, has an inertial separator.  Very
effective at getting dust, stones, hail and bird parts from going into the
675 hp turbine.

I've also seen inertial separators for intercooler air on turbo setups.
Something like the inertial path passes through the cowling, and there
in a secondary separated flow which goes to the intercooler.  Always
air-to-air on the ones I've seen.
