High-efficiency, energy-saving, and low-noise local fans for metal mines are suitable for ventilation in tunnels with various cross-sections, as well as for pit ventilation, dragline air intake, ventilation in sub-level caving methods without pillars, other local ventilation, and certain auxiliary ventilation. They can also be used for tunnel construction and underground engineering projects requiring ventilation with wind tubes.
Key Features:
1. High operational efficiency. The single-stage and double-stage impellers achieve maximum total pressure efficiencies of 92% and 83%, respectively, while the counter-rotating impeller reaches a maximum total pressure efficiency of 85%.
2. Comprehensive specifications and strong adaptability. The air flow distance of the local fan ranges from 80 meters to 600 meters, catering to various different needs of users.
3. Compact size, light weight, and easy to move around.
4. Low noise level. A silencer can be provided upon special customer requests.
