Significance of centrifugal fan model: It consists of basic model and supplementary model.
If the basic models of the fans are the same, but the purposes are different, symbols such as “G” or “Y” are added before the basic models for the convenience of distinction.
“G” means the blower (blower); “Y” means the induced fan.
The supplementary model number consists of two digits.
For example 4-72No.8C/22KW-4 left 45°
4-72: 4-72 centrifugal fan, 4-total pressure coefficient, 72-specific speed
No.8: machine number
C: belt drive
Pa: wind pressure unit (Pa)
m³/h: air volume unit (cubic meters per hour)
22KW: motor power
Y180l-4: Type 180 motor base, 4-stage motor
1600r/min: fan speed
Left: Fan rotation direction
45°: Air outlet angle
20°C: Operating temperature
