Counter-rotating axial flow fan

  SARM series double-blade wheel axial flow The diameter of the wind turbine wing blade is 1400mm The air volume can reach 300,000m ³ /h Backward wing type Convenient connection and ultra-low noise It is suitable for large flow and low pressure ranges Energy-saving efficiency: 83%   The core advantage is first and foremost high efficiency and low consumption: It adopts an aviation-grade airfoil blade design, with a fan efficiency exceeding 82%, saving 15% to 20% energy compared to traditional axial flow fans. With an optimized hub structure, the airflow disturbance is minimal, and the operating noise is 5 to 8 decibels lower than that of similar products, achieving a balance between energy efficiency and quietness.
