Typical Plan For Multi-Level Homes
For a 200–300 m² villa, one Aprilair unit can be placed outdoors, in an equipment room, garden area or terrace. The fresh air outlet is usually arranged in an open area such as the living room.
Suitable reference range for many villa layouts.
One unit can support multi-level fresh air delivery in open spaces.
Living room or central open space is preferred for better air diffusion.
Outdoor And Indoor Installation References
Aprilair can adapt to different house types, including flat homes, duplex homes, three-floor villas, four-floor villas, classrooms and large open spaces.
Garden / Terrace / Exterior Wall
Recommended when outdoor wall space is available. It reduces indoor space occupation and keeps maintenance convenient.
Closed Balcony / Utility Room
Suitable for finished apartments or villas where the fresh air duct is introduced through a balcony wall opening.
200–600 m² Villa Projects
Large airflow and high static pressure help support multi-level air renewal and balanced indoor air quality.
Ready For Clean Fresh Air
After installation, check the unit fixing points, duct connection, indoor outlet, controller response, power connection, airflow direction and operation sound.
