air enters the particle separator tubes, the vortex
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).
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
