how to choose a right fan blade for AC outdoor unit

Using the example specification  ① Ø536×153 (unit: millimeters/mm):
② Ø536: The diameter of the fan blade (the overall width of the blade, measured from tip to tip across the center).
③ 153: The axial height of the fan blade (the vertical height when the blade is placed on a horizontal surface, which determines the required installation space).
④ Ø12: The inner diameter of the motor shaft hole (the size of the central hole that fits onto the motor shaft).

Key Notes for Replacement：

  • The most important reference dimension is the shaft hole diameter. This must match the motor shaft size for proper installation and operation.
  • Minor variations (1-2 mm) in the fan blade diameter or axial height will not affect performance or installation.
💡 In short, when choosing a replacement blade, always confirm the shaft hole diameter first. Small differences in overall size are generally acceptable.
