Functional principle

How Nakoair works

The sun shines on the special heating-absorption board and the surrounding air absorbs heat. Nakoair® solar air collectors take in air at the bottom of the panel; through a special construction the air is heated by the sun and then delivered into the room. The heated fresh air is blown in by a fan driven by a photovoltaic panel.

Two series, different functions

OS20 / OS30 — Standard function

Heating outdoor fresh air. The ventilator turns and brings in the heated fresh air. Used in spring, autumn and winter. Applicable to all models.

Standard function

OS22 / OS32 / OS42 — 2-in-1 function

Heating outdoor fresh air and heating indoor air in circulation mode. You can use only the air intakes that heat fresh outdoor air, or close the air inlet to heat indoor air. This is the best way to heat the room. Applicable to OS22/32/42.

When the outdoor temperature is too low, open the indoor air inlet to keep heating indoor air; close it to introduce and heat fresh outdoor air.
