North fan combined ventilation equipment: 3 axial fans, powered at 600 KW.
South portal fan combined ventilation equipment: 3 axial fans powered at 990 KW.
They are usually cheaper than axial fans and simpler in construction.
Examples of axial fans are:
They are typically quieter than comparable axial fans.
Most industrial fans may be categorized into one of two general types: centrifugal fans and axial fans.
This instantaneous blade adjustment capability is an advantage that is possible with axial fans only.
The later type cost more, but they are more efficient and will last longer than the axial fans.
It uses higher pressure water and air, while a fan gun uses a powerful axial fan to propel the water jet to a great distance.
The sound power produced by centrifugal fans and axial fans can be approximated by a simple equation:
