The double inlet radial centrifugal fan is equipped with high-quality bearings, so it can be kept stable for long-term operation, long service life and continuous use for a long time. The stepless speed regulation is realized by PWM. Under the same working conditions, the double inlet radial centrifugal fan is more energy-saving and efficient than the conventional fan.
The double inlet radial centrifugal fan not only has the function of ventilation, but also functions as heat dissipation and air purification. The machine is based on the principle that kinetic energy is converted into potential energy. The high-speed rotating impeller accelerates the gas, then decelerates and changes the flow direction, so that its kinetic energy is converted into potential energy (pressure).
In a double inlet radial centrifugal fan, the gas will become radial after passing through the fan impeller and then enter the diffuser. In the diffuser, the gas changes the flow direction to cause deceleration, which converts kinetic energy into pressure energy. The pressure increase process is mainly caused by the impeller in the double inlet radial centrifugal fan, followed by the expansion process.
