Advantages of Fresh Air System
PM2.5 Filtration
Fresh air systems are equipped with filters that capture harmful PM2.5 particles, ensuring cleaner air enters the home. Meanwhile, the exhaust function removes indoor floating dust, keeping the air fresh and balanced.


Reduces Formaldehyde Exposure
Formaldehyde is a common pollutant in newly renovated spaces. Continuous ventilation from a fresh air system helps keep indoor formaldehyde levels low, providing an effective and widely adopted solution.
Maintains Fresh Indoor Air
Even with doors and windows closed, mechanical ventilation ensures continuous air circulation, preventing stuffiness and maintaining a fresh indoor environment 24/7.


Blocks Outdoor Noise
In modern buildings, windows are primarily for light and emergency use. Fresh air systems bring in clean air without the need to open windows, helping block out disruptive outdoor noise.
Keeps Indoor Spaces Cleaner
With fresh air systems, homes can stay sealed from outdoor dust. The airflow circulation not only prevents dust from entering but also removes it efficiently from the indoor environment.


Prevents Mold and Deterioration of Belongings
Consistent ventilation helps control humidity, protecting furnishings, clothes, and stored goods from mold, moisture damage, and spoilage—ensuring a healthier and longer-lasting indoor environment.

Precision Core Processing
The total heat exchange core is made of special materials through precision manufacturing technology, with large heat exchange area, good air tightness and long service life.
Optimized Air Duct Design
The internal air duct is optimized by fluid dynamics simulation, featuring low air resistance, even air supply, low noise and excellent energy efficiency.
Intelligent Control System
Equipped with an intelligent control module, it supports automatic air volume adjustment, filter replacement reminder and linkage with building systems.
Whole-machine Sealing Technology
Strict sealing treatment is adopted for casing joints and pipeline interfaces to avoid air leakage and short circuit, and ensure heat exchange efficiency.
Application Scenarios of Fresh Air System
Residential areas
Fresh-air systems can operate continuously to safeguard the respiratory health of all household members.
Office buildings and other workspaces
In densely occupied environments, they enhance comfort and can even boost productivity.
Commercial spaces (hotels, shopping centers)
By creating a pleasant atmosphere, they improve the overall experience for visitors and raise the quality of the venue.
