FBD Series of explosion-proof, pressure-type, contra-rotating axial flow local ventilation fans for mines

Local ventilation fans for coal mines are essential ventilation equipment in the mining and excavation process, especially the FBD series of explosion-proof, pressure-type, contra-rotating axial flow local ventilation fans. They are widely used for pressure-type long-distance ventilation in the excavation of large and small cross-section roadways in coal mines, and can also be used for ventilation and air exchange in industrial fields such as metallurgy, petrochemicals, power, railways, and highway tunnels. This series of ventilation fans are reasonably matched with the ventilation parameters of coal mine roadways for excavation construction. This series of fans features high flow rate, high pressure, and high efficiency.

The side-inlet air silencing device, combined with the inlet and outlet silencers, significantly reduces noise. Meanwhile, the silencer material uses oil-immersed glass fiber felt, which has anti-static and flame-retardant functions. The fan is designed to reduce operating noise from three aspects: aerodynamic noise, motor electromagnetic noise, and mechanical noise. The noise complies with JB/T8690-2014 "Noise Limits for Industrial Ventilation Fans".
