How Does the AP450/AP720 Fresh Air Supply System Work?
The AP450 and AP720 fresh air systems operate by drawing outdoor air through a filtration process to reduce dust particles and PM2.5, as well as airborne pathogens, before delivering clean, fresh air into the building.
The system works through the following steps:
- Filter outdoor air
The system filters outdoor air, effectively removing PM2.5 particles and airborne pathogens to improve air quality indoors. - Release purified oxygen (O₂)
Fresh oxygen is introduced into the space to improve air quality and reduce the accumulation of pollutants. - Create positive air pressure
Positive pressure is maintained in the room to prevent unfiltered outdoor air from entering the building. - Vent stale indoor air
Stale indoor air is expelled to maintain balanced and comfortable indoor air conditions.
Thanks to this multi-step process, the AP450 fresh air system helps ensure a clean, fresh, and safe indoor environment—ideal for residences, offices, hospitals, and other indoor spaces where high air quality is essential.
