Underground Local Ventilator

Underground Local Ventilator:

JK series mining machine fan product introduction

The high-efficiency and low-noise JK and DJK series mining local ventilators are suitable for various specifications and cross-sections of tunnel excavation ventilation, stope and roadway ventilation, ventilation and other local ventilation and partial auxiliary ventilation. It can also be used for ventilation in tunnel construction, underground engineering construction and other occasions where air duct supply is required.

Features of JK series underground local ventilator

1. High operating efficiency. The high total pressure efficiency of the single-stage and double-stage working wheels is 92% and 83%, respectively, and the high total pressure efficiency of the counter-rotating type is 85%.

2. Complete specifications and strong adaptability. The air supply distance of the local fan varies from 80 meters to 600 meters, which can meet the various needs of users.

3. Small size, light weight, flexible and convenient to move.

4. Low noise. When the user has special requirements, it can be equipped with a muffler.

5. There are many varieties and specifications and strong selectivity. The JK series of local fans has a total  of  21 varieties ranging from 3.0# to 8.0#, which can adapt to different types of ventilation needs.

6. High efficiency and obvious energy saving effect. The working efficiency of single-stage impeller and double-stage impeller are 92% and 83% respectively, and the efficiency of DJK series anti-cyclone separator can reach 85%.

7. Low noise. In practical underground applications, the maximum noise does not exceed 86 decibels. If the underground noise is low, the corresponding muffler can be selected according to customer requirements.

8. Small in size, light in weight and easy to use, JK series fans are small in size and light in weight, and can be used flexibly in underground wells, reducing the labor intensity of workers.

9. The fan design is novel, and the blade adopts ternary fluid design, which has good aerodynamic performance and obvious energy saving effect.

10. The fan is directly connected with the motor and blades, the fan runs smoothly and can be ventilated for a long time.

11. The motor voltage can be selected from various voltages such as 380/660, which can meet the needs of different mines.

underground local ventilator have the advantages of high efficiency, low noise, energy saving and environmental protection.
