配变频调速电机，风量风压随掘进深度在25～50Hz无级调节，节能显著；双叶轮相对旋转，压力达单级3倍；风量大；四节消声装置，噪声低；独头送风可达1000～5000米；对电机和电网冲击小。
【English】Equipped with a variable frequency speed-regulating motor, air volume and pressure adjust steplessly between 25–50Hz as excavation extends, with significant energy savings; dual counter-rotating impellers deliver three times the pressure of single-stage; large air volume; four-section silencing device for low noise; dead-end air supply up to 1,000–5,000 meters; minimal impact on motor and power grid.
