Fan Clutch Without Thermostatic Control: Description
This unit is basically the same as the thermostatically controlled fan clutch except it is not controlled by a temperature sensitive coil. The fan clutch allows the fan to be driven in a normal manner at low speeds while a higher engine speed limits the rotational speed of the fan to a predetermined rate. The silicone in the clutch housing provides a more positive drive at lower speeds and allows greater slippage between the driven member and driving member at higher engine speeds.
