YBT series explosion-proof axial flow local ventilation fan for miningDetailed product description：

·Scope and Application

The YBT series explosion-proof axial flow local ventilation fan is suitable for use in environments with explosive mixtures of gases such as methane and coal dust in coal mines and their surrounding media. It is used for local ventilation in underground mining and coal mining tunnels in circuits with AC 50Hz and voltage of 380V or 660V. It is particularly suitable for local ventilation in long blind tunnels and can also be used for ventilation and air exchange in large buildings.
