Induced draft fans (ID fans) often handle air under harsh conditions, including high temperatures, sour drafts, and other extreme exhaust gases. They concentrate volume and pressure at the fan inlet, moving air and other materials or elements through the system. Extreme conditions may require special attention to unbalance, excessive vibration, temperature, maintenance and operating costs, but they can also operate at higher efficiencies relative to forced draft fans.

1. It can work stably at a high medium temperature, and can output a large gas flow with low noise when the pressure requirement is met.

2. The fan blade placement angle is optimized, more wear-resistant and longer service life.

3. The air damper can be used to flexibly adjust the pressure and flow of the fan during operation. It is also possible to select a variable frequency motor, with adjust the pressure and flow of the fan by changing the speed.

4. For the material of impeller and main shaft, we will choose high-strength carbon steel, low-alloy steel,  high-temperature alloy steel, high temperature resistant high-strength alloy steel under different working conditions temperature and working speed, so that the impeller and main shaft still maintains a reliable strength at high temperature.

5. Fan systems with impeller diameters less than 1400 mm at normal temperature do not require additional bearing cooling devices, reducing users’ investment and maintenance.

6. The impeller is annealed to eliminate the internal stress generated during welding, ensuring that the impeller does not undergo creep and cracks.

7. The weld of the impeller and the main shaft are ultrasonic flaw detection to ensure that there are no welding defects and material defects to ensure strength.

8. The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.

9. There are a variety of accessories to choose from.
