generator creates a swirling action.

Using centrifugal

force, the swirling action throws the heavier particles

suspended in the air outward. The contaminates flow out of

the tubes through the opening in the tube's outer wall.

The clean air, in the eye of the vortex, continues to the

outlet tube and is used for cooling air. The contaminates

flow overboard through the ejector. A jet pump, using air

from the tapoff prior to the venturi, induces the movement

of the air through the ejector (fig. 1-44).



If the particle separator scavenge airflow

stops, the separation of contaminants from the cooling air

becomes ineffective and contaminants will enter the system

and cause premature wear on the fan section of the ACM and

the precooler; heat exchangers passageways could become

clogged, resulting in higher than normal temperatures. If

the tubes in the separator become clogged, reducing the

flow of cooling air, higher than normal temperatures

result.
