FBD Series Explosion-proof Pressure-type Counter-rotating Axial Flow Local Ventilation Fan for Mines

Local ventilation is essential equipment in the mining and excavation process of coal mines, especially the FBD series explosion-proof pressure-type counter-rotating axial flow local ventilation fan. It is not only widely used in the pressure-type long-distance ventilation of large and small cross-section roadways in coal mines, but also can be used for ventilation and air exchange in the industrial fields of metallurgy, petrochemicals, power, railways, and highway tunnels. This series of ventilation fans are mining roadway ventilation parameters reasonably matched with the excavation construction ventilation fans. 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 greatly reduces noise. At the same time, the silencer material uses oil-immersed glass fiber felt, which has anti-static and flame-retardant functions. Starting from the design, the fan takes measures from three aspects: aerodynamic stability, motor electrical noise reduction, and mechanical noise reduction, effectively reducing the operating noise of the fan; the noise complies with JB/T8690-2014 "Noise Limits for Industrial Ventilation Fans".
