1. General
The Mining Explosion-proof Axial Flow Fan is used in explosive gas(Methane) mixed air in the coal mine. With rated voltage 660V, AC(Alternating current) 50HZ electric system, used for excavating the tunnel. And it also used in metal mine, chemic mine, tunnel, and other factories and mines. The temperature of the blowing medium can not exceed 40℃. 

2. Construction specifications

The YBT series mining explosion-proof axial flow fan is made up from explosion-proof motor, impeller, air duct and junction box. The flow fan is axial-flow type. The impeller is connected directly with the explosion-proof motor, hold them very tight by the bolt and the clamp. The heat emission of the motor by its own cooling fin on the base and cooled by the axial airflow directly.
