The FBD series explosion-proof double-suction axial flow local ventilator for coal mines is a new generation, widely applicable, energy-saving local ventilator developed and produced by Zibo Blower Factory Co., Ltd. Based on the summary of the existing double-suction axial flow local ventilator structure and technical performance in China. This product features rational structure, complete specifications, high efficiency, significant energy-saving effects, low noise, and long air delivery distance. It can be used either as a whole unit or in stages according to different ventilation resistance requirements, thereby reducing ventilation electrical consumption and energy savings. For tunnels up to 2,000 meters in length, the ventilator can operate normally without movement, reducing labor intensity for workers and saving ventilation time, making it an ideal equipment for local ventilation in coal mine underground. Additionally, it is also suitable for high-pressure ventilation in metallurgy, non-ferrous metals, gold, chemicals, shipbuilding, and ceramic industries. Its structural characteristics include mine explosion-proof, double-suction, noise reduction, and axial flow. Main Applications and Scope: This product is primarily used as an explosion-proof local ventilator in coal mine underground and is suitable for local ventilation in various adits for mining operations. It is also applicable to local ventilation in other mines and various tunnel ventilation.
