Core advantage

1. Precise Airflow Control & Efficient Air Delivery

Airflow is adjusted according to the needs of different scenarios such as residential, commercial, and industrial environments. The strong pressure easily overcomes resistance from pipe length and elbows, eliminating insufficient airflow issues to ensure efficient ventilation and exhaust performance.

2. Flexible Adaptation & Easy Installation

Inlet and outlet port diameters precisely match pipe dimensions. Compact design enables the fan fits ceiling, wall corner, and other installation spaces for convenient installation without wasting space.

3. Durability & Stability

The fan has undergone reliability testing at -40°C to 65°C for 40,000 hours. The electric engine features built-in overheating and overload protection. The material of the casing and the impeller is corrosion-resistant, reducing the failure possibility during long-term use and significantly lowering maintenance costs.

4. Low-noise & Economic Efficiency

Operating noise ≤50dB, quiet and non-disturbing. The fan adapts a high-efficiency motor with an F class insulation, significantly reducing energy costs over long-term use.

5. High Environments Adaptability

Different protection levels of motors is optional according to different usage scenarios and transport media, such as ordinary air, cooking fumes, corrosive gases and more, protection class up to IP54.
