2-stage turbo fan
High efficiency design by 2 stage structure
+
2 stage
Previous turbo fan
In the case of aconventional fan, the airoutlet range was narrowas the airflow moved to
the motor side whichmeant the velocity of airpassing through the heatexchanger was uneven.
2-stage turbo fan
A evenly spread air distribution acrossthe heat exchanger is possible dueto the new 2 stage turbo fan whichproduces two separate airflow
streams.

Filter features
The filter deodorizes by powerfully decomposing absorbedodors using the oxidizing and reducing effects of ionsgenerated by the ultra-fine particle ceramic.*The filter can be used for approx. 3 years if i t is washed under water to restoreit's surface action when it is dirty.
Long-life*Ion deodorization filter
Fine dust, invisible mold spores, and harmful microorganismsare absorbed onto the filter by static electricity, and furthergrowth is inhibited and deactivated by the polyphenolingredient extracted from apples.
