Recovery+Preheating

integrated-wall-mounted-fresh-air-ventilator

This fresh air system uses a ceramic heat recovery core + integrated PTC preheating design. During exhaust, it efficiently recovers indoor heat and preheats the incoming outdoor air, helping improve winter supply-air comfort. With a 300W integrated heating module and a heat recovery efficiency of up to 97%, it delivers a stable and gentle airflow even in low-temperature conditions, reducing the discomfort caused by cold drafts. It is suitable for users and projects that value winter ventilation comfort, energy-saving air exchange, and better indoor air quality.

Freeze Protection

This system features freeze protection with auxiliary heating that helps eliminate heat exchanger frost risk, ensuring reliable air exchange even in frigid climates. It maintains constant airflow in low-temperature conditions, improves low-temp adaptability, and adds an extra layer of system protection for stable operation throughout winter.

500W PTC Electric Heating Tngechnology

Smart Temperature Protection: The built-in intelligent temperature controller monitors the PTC heating temperature in real-time. If the temperature becomes too high, the system automatically shuts off the heater to ensure safe and stable operation.

Extreme Cold Protection: When the outdoor temperature drops below -20°C, the system automatically activates low-temperature protection, stopping the motor to prevent damage and enhance durability and reliability.

Warm Fresh Air

Actively reduce dust, pollen, smoke, bacteria, and viruses in the air.

Improve air quality by causing fine dust particles (including PM2.5) to cluster and settle, effectively removing airborne pollutants.

Research from the United Nations confirms that ecological-grade negative ionizers can efficiently capture and eliminate microscopic particles, enhancing indoor air quality.
