The tangential inlet and outlet nozzles of air separators create a
low velocity centrifugal force which propels the heavier "air free"
condensate towards the outer edges. The entrained air is released
into the center of the swirling vortex and upwards towards the top of
the vessel where it can be vented with a
float style air vent
Systems using air separators often require less chemicals for pH and
corrosion control because dissolved oxygen, carbon dioxide and other
non-condensable gasses are removed from the condensate on its way to the
the feed tank.
