Series mine ground explosion-proof pull-out axial flow fan | Explosion-proof fan | Draw-out fan | Mine axial flow fan
Product Description
rrr fan overview
Series mine ground explosion-proof pull-out fan The axial flow fan is a new type of main fan with large air volume, low air pressure, high efficiency and energy saving that is widely used. It is developed based on the ventilation network parameters of small and medium-sized coal mines. It can meet the ventilation requirements of small and medium-sized coal mines and large coal mines where multiple fans operate jointly. It is more suitable for the needs of large air volume and low wind resistance mines currently dominated by fully mechanized mining machinery. This machine has the characteristics of compact structure, high efficiency, significant energy saving effect, low noise, and good anti-wind performance. It is an ideal ground main fan. This product is also suitable for metal mines, chemical mines, tunnels and other factories and mines where fans are used.
