For healthy breathing
As quality of life improves, tall buildings rise up,
and spacesbecome more confined;
As health needs increase, the economy develops,
and environmental pollutionbecomes worse;
When healthy breathing becomes a luxury,
Ventilation system creates healthy air for you,
Ventilation system allows you to breathe more freely,
Ventilation system—For healthybreathing!

IntelligentFreshAirControl Technology
Quadruple Action Energy Saving Technology
An industry-leading intelligent freshair detection and control system that monitors indoor pollution in real-time，automatically adjusting the intake and exhaust airflow based on air quality.It operates without the need for manual intervention, offering smart control and enhancedpeace of mind.
The fan assembly incorporates a high-pressure, high-volume, low-power, high-speed DC brushless motor,a patented air chamber structural design, and an innovative heat exchanger core utilization model. These four effects are combined to achieve maximum energy efficiency， consuming less than one kilowatt-hour of electricity during 24 hours of continuous operation.
HEPA High-Efficiency Purification Technology
Professional Soundproof Technology
Employing HEPA air purification technology， it provides three layers of efficient fltration for indoor air， effectively filtering PM2.5 particles, bacteria, dust, and repelling harmful pollutants such as formaldehyde and benzene, with a filtration efficiencyof up to 99.9%
Employing high-grade DC brushless fans, proprietary air duct designs, sound-dampening chambers, and optimized outlet vents,coupled with advanced multi-stage noise reduction techniques, our fresh air systems achieve ultra-quiet operation. In quiet mode, noise levels are reduced to as low as 32dB,ensuring a serene sleep environment for the entire household.
Two-Way Cold/Heat Recovery Technology
360° Circulating Air Technology
Theleading two-waycold/heatexchange technologyreduces the temperature difference betweenindoor and outdoor air.In winter，it reduces indoor heat loss, while in summer， it makes the incoming air cooler and more comfortable,compatible with GB21087 standards.
Features exclusive 45° angle air outlet design, combined with fluid mechanics. When the air rubs against the walls, the air flows along the walls, forminga 360° circulating fresh air system with no dead angles. It delivers swift and complete fresh air purification throughout the entire home.
