2-stage turbo fan

High efciency design by 2 stage structure
+
2 stage
Previous turbo fan
In the case of a
conventional fan, the air
outlet range was narrow
as the airow moved to
the motor side which
meant the velocity of air
passing through the heat
exchanger was uneven.
2-stage turbo fan
A evenly spread air distribution across
the heat exchanger is possible due
to the new 2 stage turbo fan which
produces two separate airow
streams.
