Our multi-stage direct-drive axial flow fan is a high-performance ventilation solution designed for tunnel engineering and heavy industrial air circulation. Operating at 2900RPM, the fan adopts a direct drive design, removing intermediate transmission parts such as belts, which reduces power loss, lowers failure points and improves transmission efficiency greatly.
Thanks to optimized aerodynamic blade design, the fan achieves stable air volume and pressure output while keeping low noise during continuous operation, creating a better working environment for construction and underground workers. Multi-stage structure enables long-distance air supply, meeting the ventilation needs of long tunnels and deep roadways.
We support custom airflow, pressure, mounting form, coating and logo according to your project requirements. The whole machine is made of thick carbon steel, with reinforced impeller that has passed strict dynamic balance test, to ensure low vibration and stable operation under continuous working conditions. The matched motor has good dustproof and waterproof performance, adapting to the dusty and humid site environment of tunnel construction.
It is widely used in highway tunnels, railway tunnels, underground pipe corridors and other ventilation projects. As a reliable manufacturer and supplier, we conduct strict performance inspection for every fan before delivery. Complete technical drawings, installation guidance and after-sales service are provided to support your engineering bidding and on-site commissioning.
