Оосевые вентиляторы SDF: высокоэффективные решения от китайских поставщиков и фабрик для вентиляции туннелей и подземных сооружений
Product Description
⚡
High Efficiency & Energy Saving
20% more efficient than standard axial fans, reducing energy consumption by approximately 15%. With variable frequency speed control, airflow can be dynamically adjusted to meet actual demand, achieving even greater energy savings.
🔇
Low Noise Level
Special acoustic design reduces noise by 5–10 dB compared to similar products. The diffuser outlet design disperses rotational noise, significantly improving the working environment.
💨
Long-Distance Air Delivery
High-pressure design enables air delivery over hundreds of meters, making it especially suitable for tunnels and long duct systems. The counter-rotating design enhances airflow stability, maintaining a consistently high air velocity (>2 m/s) over long distances.
🛡️
Reliability & Durability
Impellers use aerospace-grade materials with high fatigue strength for a long service life. The robust structure withstands harsh conditions (high temperature, humidity, dusty environments) and is equipped with comprehensive anti-corrosion and explosion-proof measures (optional).
