Why are fan blades NEVER slanted right on fans and go only left? This is not quite true...
MOST fan blades [except special application units for the most part] would be this way because the standard fan motor runs clockwise, rather than counter-clockwise.
Therefore, MOST [not all] fan blades are designed and installed to provide maximum design airflow running clockwise!
The reason? I don't know! Motors will happily run clockwise or counter-clockwise depending on how the windings are connected. Three phase motors run either way depending on phase order, and can be reversed by switching any two phase connections to the motor.
Ceiling fans are designed to run BOTH WAYS and have a switch built in to allow the change from CW to CCW!
Rolls Royce and General Electric both make jet engines. You can check the engines on the next flight you take to see if they are RR or GE. What�s the difference? In RR engines the fan blades rotate clockwise, while all GE engine fan blades rotate counterclockwise.
There is always a "practical" reason for standards.
MOST bolts tighten clockwise, BUT NOT ALL! Why is that?

Is fan operating in ac voltage?
A fans blades are driven by motors. Since there are both AC and DC motors, fans can be AC or DC. The fans in your computer are DC fans. Your ceiling fans are AC fans. (Thanks for fixing my answer)
What do the blades of a wind turbine look like?
They look like propellers, or fans.
Why do fans have 3 wings?
An electrical fan can have two, three or four blades. The main thing is that the number of blades must be balanced to avoid juddering.
When power a fan using a simple electric motor the fan's shaft and blades are attached to?
Fans shaft and blades are attached to rotor shaft of the motor
What is a group of fans called?
An audience i think :)
What is minimum distance to install two fans in the same room?
That depends on the length of the blades on the fan.
What are never shout never fans called?
They call them fans, they dont call them anything else...
How exactly do electric fans work?
Electric fans work by forcing the air directly in front of its tilted blades away. The continuous rotation of the fan blades create a stream of fast moving air that has a cooling effect as it moves through an area and over surfaces.
How do ceiling fans push heat down?
Fans doesn't push heat or cold down but pushes air with force in the direction which is determined by the position of blades of fan.
