K40 mining energy-saving ventilation fan is specially designed according to the needs of various non coal mines such as metallurgy, non-ferrous metals, gold, chemical, building materials, and nuclear industries. It can be used as a main fan and auxiliary fan, and can be installed on the surface or underground. It is suitable for multi fan joint operation and is the ideal fan for each level of fan station in the multi fan series parallel multi-stage fan station ventilation system. It is also suitable for ventilation and air exchange in large workshops, tunnels, civil defense projects, and other occasions.

The main features of K40 mine energy-saving ventilation fan are:

1. Low noise.

2. Diverse performance and complete specifications, it can be well matched with ventilation networks of various resistance and air volume types, and can maintain long-term efficient operation.

3. Equipped with a stabilizing ring device, the characteristic curve has no hump, no surge danger, and can operate safely and stably under any resistance state, suitable for multi fan joint operation.

4. The structure adopts a direct connection between the electric motor and the impeller, with good overall stability, easy installation, easy maintenance, and low local resistance of the device.

5. Compact structure and good moisture resistance. The main body of the fan adopts a welded structure of steel plate and section steel, and the blades are made of steel plate material, hollow. The blades and the whole machine have high strength and strong resistance to underground blasting shock waves. They can be installed on the surface and are also suitable for installation underground, especially as fan stations for multi-stage ventilation systems.

6. The amount of civil engineering work is very small, which can save a lot of investment.

7. The installation angle of the blades can be adjusted, and the fan condition can be adjusted at any time according to the changes in mine production.

8. K can reverse the reverse wind, with a reverse wind rate greater than 60%, and there is no need to build a reverse air duct.

9. Adopting twisted wing shaped blades, the aerodynamic efficiency is high and the energy-saving effect is extremely significant.
