Replacement cooling fan for Castellotti model H71 electric motors, used in professional meat slicers (including Sirman-branded models). The fan is keyed onto the motor shaft and, as it rotates, forces the air flow over the windings to dissipate their heat: it is an essential component to prevent overheating and extend the life of the motor.

Technical specifications:

• Outer diameter: Ø 105 mm
• Bore diameter (shaft): Ø 11 mm
• Application: Castellotti model H71 motors for meat slicers

When to replace it: the fan should be changed if the blades are broken, cracked or deformed, if it sits loose on the shaft, or when you notice unusual vibration, noise or excessive motor heating during use. An intact fan ensures proper cooling and smooth, balanced rotation.

Practical tip: before purchase, check the bore diameter (11 mm) and the outer diameter (105 mm) to make sure it is compatible with your motor. When fitting, position it correctly on the shaft and pair it with its fan cover.
