FBD series explosion-proof pressure-type contra-rotating axial flow local ventilation fan for mines

Local ventilation in coal mines is essential ventilation equipment during mining and excavation, especially the FBD series explosion-proof pressure-type contra-rotating axial flow local ventilation fan. It is widely used for pressure-type long-distance ventilation in large and small cross-section roadways in coal mines, and can also be used for ventilation in the metallurgy, petrochemical, power, railway, and highway tunnel industries. This series of ventilation fans are reasonably matched with the ventilation parameters of coal mine roadways and are used for excavation construction. This series of fans features high flow rate, high pressure, and high efficiency.

The side air intake silencer, 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 noise from three aspects: aerodynamic stability, motor electrical noise reduction, and mechanical noise reduction, effectively lowering the operating noise; the noise complies with JB/T8690-2014 "Noise Limits for Industrial Ventilation Fans".
