Coal mine ground use ventilation fan

The coal mine ground use a large air -volume shaft circulation fan is a device specifically used for coal mine ventilation systems. By generating a large amount of air flow, it discharges harmful gas such as gas, coal and dust from the underground to ensure the circulation and quality of air in the mine, and ensure the safety of miners. The main features of large air volume axis circulation fans are large air volume, high wind pressure, low noise, and high efficiency. It adopts a shaft -type fan blade design, so that the air volume can fully spread, the coverage is wide, and it can effectively discharge the harmful gas in the mine. At the same time, it also has high wind pressure, which can overcome the resistance in the mine and ensure that the airflow can flow smoothly. The large air -volume shaft circulation fan also has a lower noise level, which is very important for the improvement of the coal mine's working environment. Because the coal mine ground ventilation system nee…
