Product Introduction
Precise wind control, energy conservation and consumption reduction

Equipped with high-precision air volume sensing and regulating modules, the adjustment accuracy can reach ±5%. It can automatically adapt the air volume size according to the ventilation requirements of the roadway, avoiding waste of air volume.

 

Compared with traditional manual air valves, the annual ventilation energy consumption can be reduced by more than 30%, significantly reducing the operating costs of overseas mines.
