This product boasts a rational structure, complete specifications, high efficiency, significant energy-saving effect, low noise, and a long air delivery distance. It can be used either as a whole unit or in stages, depending on the ventilation resistance requirements, thereby reducing ventilation time and saving energy. For tunnels up to 2000 meters in length, the ventilator can deliver air without relocation, which reduces labor intensity for workers and saves ventilation time, making it an ideal equipment for local ventilation in coal mines. Additionally, it is also suitable for high-pressure ventilation scenarios in metallurgy, non-ferrous metals, gold, chemicals, shipbuilding, and ceramics. The ventilator's structural features include mine explosion-proof, counter-rotating, noise-reducing, and axial flow.
