2-stage turbo fan

High efficiency 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 airflow 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 airflow
streams.

The filter deodorizes by powerfully decomposing absorbed
odors using the oxidizing and reducing effects of ions
generated by the ultra-fine particle ceramic.
*The filter can be used for approx. 3 years if it is washed under water to restore
it's surface action when it is dirty.

Ion deodorization filter
Fine dust, invisible mold spores, and harmful microorganisms
are absorbed onto the filter by static electricity, and further
growth is inhibited and deactivated by the polyphenol
ingredient extracted from apples.
