Filtech International's 9-08 series centrifugal ventilation fan

Filtech International’s The 9-08 series high pressure fan is generally used for forging furnace and high pressure forced ventilation, and can be widely used to transport materials, transport air and non-corrosive, non-self-igniting, non-viscous substances gas.

Applications

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,etc.

Product Features

The fan can output higher gas pressure, and can provide more gas flow at the same time, low noise.

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.

There are a variety of options to choose from.
