Осевые вентиляторы SDF от китайских производителей: высокоэффективные решения для вентиляции туннелей и подземных сооружений
20% more efficient than standard axial fans, reducing energy consumption by approximately 15%. With variable frequency speed control, airflow can be dynamically adjusted to actual needs for even greater energy savings.
A specially designed acoustic structure reduces noise by 5–10 dB compared to similar products. The diffuser window design disperses rotational noise, significantly improving the working environment.
The high-pressure design delivers air over hundreds of meters, making it ideal for tunnels and extended duct systems. The counter-rotation design enhances airflow stability, maintaining a high air velocity (>2 m/s) over long distances.
Impellers use aerospace-grade materials with high fatigue strength for a long service life. The robust design withstands harsh conditions — high temperatures, humidity, and dusty environments — with comprehensive anti-corrosion and explosion-proof options available.
This fan is approximately 20% more efficient than standard axial fans, resulting in around 15% lower energy consumption. When combined with variable frequency speed control, energy savings can be even greater by dynamically matching airflow to real-time demand.
The fan features a specially designed acoustic structure that reduces noise levels by 5–10 dB compared to similar products on the market. The diffuser window design effectively disperses rotational noise, creating a quieter and more comfortable working environment.
Yes. The high-pressure design enables air delivery over hundreds of meters, making it especially suitable for tunnels and extended duct systems. The counter-rotation design ensures stable airflow with a sustained high air velocity of over 2 m/s even at long distances.
The impellers are made from aerospace-grade materials with high fatigue strength, ensuring a long and reliable service life. The overall construction is engineered to withstand harsh operating conditions including high temperatures, high humidity, and dusty environments.
Yes. The fan comes with comprehensive anti-corrosion protection as standard, and explosion-proof configurations are available as an option. This makes it suitable for demanding industrial environments such as chemical plants, mines, and other hazardous locations.
