Part Two
The features of centrifugal fan

centrifugal fan

1. Structure: 
Compact structure, beautiful appearance, good stability, what's more easy installation and convenient maintenance.

2. Stable operation: 
Optimal design of the impeller makes the axial force to minimum, and the efficiency is high.After static and dynamic balance correction, the impeller make the machine running smoothly, and in the absence of any vibration damping device case, bearing amplitude is less than 0.04mm.

3. Low noise: 
During the centrifugal blower running,there is no mechanical friction. Centrifugal fan adopting reasonable blade-shaped line to make the voice drop to a minimum. Centrifugal fan noise 
belongs to high-frequency noise, as long as there are obstacles, they can deaden the noise. 

4. Oil-free machinery: 
Centrifugal blower bearings use grease lubrication, and bearing life is more than three years. Centrifugal fan does not produce oil gas during the operation.

5.Impeller: 
Impeller adopts special compound linear, reduces the internal leakage, increases the volumetric efficiency.

6.Air adjusting: 
Adjusting door is easy to operate to control airflow and air pressure. 

7.Motor
According the differenct grid of customers, the blower can be equipped with variable frequency motor, high voltage motor, explosion-proof motor, or different voltage motor. 

8.Cooling
Bearing housing have two cooling methods, water-cooling, oil-cooling, all these prolong the service life of bearing. 

9.Driving modes
There are direct driving, belt driving, coupling driving. According to the equipments and performance, the blowers can choose suitable driving mothod.
