On my fan their is a little switch on the side if the neck of the fan
if it is a car engine we can answer by seeing its cooling fan design or fan blade profile.
four blade
The electric cooling fan on a 97 Dodge Neon turns the blades in a clockwise rotation. This pulls air through the radiator and across the engine.
a reverse fan blade and fan clutch
A fan motor rotates in the direction dictated by the type of blade it is using to move air in the desired direction. Both CW and CCW blades are used to do the same thing(move air in a particular direction). It simply depends on which type of blade one has in order to accomplish this and whichever blade you have will determine the direction of rotation of the motor driving it.
It is the radius of the fan blade.
how do you remove a fan blade from a 1998 ford explorer
The wench will be used to remove the clutch fan nut. Remove the nuts holding the fan then remove the fan blade.
Usually twist handle to open
Indoor fan = steel, Outdoor fan = aluminum.
Ceiling fans should be equipped with a reversing switch to operate in a forward or reverse rotation. The ceiling fan should move the air down in the summer time and draw the air up in the winter time. The rotation of the table fan is governed by the manufacturer of the blades. These blades are contracted out and bought from a different company and the fan manufacturer will buy the cheapest ones possible. The manufacturer of the fan doesn't care what pitch blade they use, as they have the ability to run the motor in either direction depending on the blade pitch.
The blade will go off if the electric fan is turned off.
