Description
Induced draft fans and blowers for boilers, single inlet
1) The Induced draft fan is as a single suction type.
2) The boiler induced draft fans usually made in left or right rotation. When viewed from one end of the motor, the impeller rotates clockwise to a right-handed fan; the counterclockwise rotation of the impeller call as Left-hand fan.
3) Express the position of the fan outlet through the outlet angle of the casing.
4) The fan transmission mode is C or D type (that is, cantilever structure). The motor and fan are connected by pulleys or couplings, using V-belts or couplings, respectively. Shaft pin drive.
5) Examples of full product names are as follows: G4-73№14C right 90 °C. G4-73№14C left 0 °C. Among them: 4 is the pressure coefficient of the highest efficiency point 10 times rounding, 73 is the specific speed, №14 means the impeller diameter is 1400 mm, C means the transmission mode is V-belt drive.
