矿用风机（K系列 / DK系列）
【中文】K系列：机翼扭曲叶片效率高，稳流环防喘振，电机叶轮直联无传动故障，抗井下爆破冲击波，直接反转反风率＞60%，土建量小。DK系列：抽出式对旋风机，内耗小、噪声低，扩散器动压转静压节能，可配变频远程调控，含瓦斯环境可制防爆型。
【English】K Series: Twisted airfoil blades for high efficiency; steady-flow ring prevents surge; motor-impeller direct drive free from transmission failure; resists underground blasting shock waves; direct-reversal airflow rate over 60%; minimal civil engineering workload. DK Series: Extraction-type counter-rotating fan with low internal loss and low noise; diffuser converts dynamic pressure into static pressure for energy savings; VFD and remote control optional; explosion-proof type available for gassy tunnels.
