Protector radio-ohjattu poistoilmanohjaus ASF-410 valkoinen (15028)

Operating a powerful kitchen exhaust fan while a fireplace or stove is burning can create dangerous negative pressure, pulling carbon monoxide back into the room. The Protector ASF-410 solves this by automatically switching the exhaust fan on only when a window is open, ensuring safe and efficient ventilation.

Who is it for

Homeowners with fireplaces, wood-burning stoves, or gas appliances who need to operate an exhaust fan without compromising indoor air quality. It is also suitable for anyone wanting automated ventilation control based on window position.
