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.
