First Stage Filtration:
Air enters at inlet port and flows through deflector
plate (A) which causes a swirling action. Liquids and
coarse particles are forced to the bowl interior wall (B)
by the centrifugal action of the swirling air. They are
then carried down the bowl wall by the force of gravity.
The baffle (D) separates the lower portion of the bowl
into a ¡°quiet zone¡± (E) where the removed liquid and particles collect, unaffected by the swirling air, and are
therefore not reentrained into the flowing air.
Second Stage Filtration:
After liquids and large particles are removed in the
first stages of filtration, the air flows through element
(C) where smaller particles are filtered out. The filtered
air then passes downstream. Collected liquids and
particles in the ¡°quiet zone¡± (E) should be drained
before their level reaches a height where they would
be reentrained in the flowing air. This can be
accomplished by unscrewing the drain valve (F)
slightly until the liquid begins to drain. |
