The 7-07 series high-pressure centrifugal fan has a high output pressure, can transport normal temperature or high temperature various gases and various forms of materials, and also can be used in harsh working environments.
7-07 series centrifugal ventilation fan Structure
7-07 series centrifugal ventilation fan Application
Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.
7-07 series centrifugal ventilation fan Features
It can output high out gas pressure and can work at higher medium temperature, suitable for any industrial occasion where high pressure & high temperature gas needs to be delivered.
Compact shape, saving space.
In the use of common base, the installation is very simple and requires little support from a professional technician.
Made of high quality carbon steel, Stainless steel or other metal materials can also be used according to user requirements.
For dusty gases, we are able to satisfy a wide range of conditions from a small amount of dust to a very high dust content, after special treatment, the surface hardness of the blade can reach HRC60~70, which can extend the life of the impeller more than 3 times.
The parts are tightly matched and the sealing performance is good, ensuring that the output pressure will not decrease.
By ultrasonic flaw detection for the impeller welding line and main shaft, ensure that there are no weld defects and material defects to ensure strength.
The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.
After the completion of production, after running test and vibration value detection, reliable operation.
