China Manufacturer of Mining Axial Fan

DW series fan is a large-scale explosion-proof axial fan for mine developed by combining the parameters of ventilation network for mine. It's with the advantages of high efficiency, energy saving and low noise. The static pressure efficiency of the product can reach above 86%, and the main fan achieved the leading level in China. The adopt explosion-proof material passed the test center of the friction spark test and reached the explosion-proof requirements. This material is approved by Chinese Academy of Sciences Chongqing Branch.the whole explosion-proof performance has passed explosion-proof test by the national explosion-proof electrical product quality testing center.

Features
1. In order to meet the resistance requirements of coal mine ventilation network, and to ensure the efficiency of the fan, the machine uses a rotating structure, the two wheels are mutually reverse rotation, you can save the guide vane and reduce the loss of the guide vane, Improve the efficiency of the fan.
2. Adopt type of motor and impeller direct connection, to avoid damage to the transmission device, but also eliminates the energy loss of the transmission device to improve the efficiency of the fan device.
3. The motor is installed in the fan main fan in the closed cover, the enclosure has a certain pressure, can make the motor and fan flow channel containing gas gas isolation, but also play a certain role in the heat, Two rows of streamlined air duct, through the main air duct and the ground atmosphere, so that fresh air into the closed cover, while the air inside the fan in the fan running to maintain a positive pressure state.
4. The maximum hydrostatic efficiency of the fan up to 86% or more, wide efficient area, to ensure that the mine in the three stages of the main fan efficiency are more than 75%. Reversing the operation of China's large-scale mine main fan low efficiency, can save a lot of power.
5. Fan can reverse the wind, the amount of air up to 60% of the air volume, do not have another anti-air duct, with savings in infrastructure investment and the advantages of fast wind speed.
6. The impeller blade angle can be adjusted, according to the requirements of production to adjust the blade angle. The fan with a special design, performance curve without hump, in any case of network resistance, can be stable operation.
7. The series of fans running stable, small machine vibration, fan and diffuser can be installed in the wheeled flatbed, can be long-term continuous operation.

Ordering instructions
When ordering, please specify the fan number, speed, air volume, wind pressure, outlet angle and direction of rotation, as well as motor model, power, speed and so on.
The most important factors are volume and pressure.

Customized
When the exiting machine number, rotation, the wind angle and transmission mode can not meet the needs of users, we can design according to the fan similar theory and the user's specific parameters requirements.
