What About Pitch?
The pitch of the blades (in degrees from horizontal)
determines how much air is blown as the blades move through the air.
More pitch means more air is moved, but its not quite that simple
as greater pitch requires a stronger motor to push all the air that
the spinning blades are blowing.
The duty of any well designed fan is to move the most air possible,
BUT with the highest efficiency. Signatures highest blade pitch
model is the 16 degree pitch MX-Excel and it uses our strongest motor
too. Optimum pitch is between 13 and 16 degrees and strikes the best
balance for air movement and efficient motor design. Lesser fans may
get by using inferior motors and often only 10 or less degrees of
blade pitch. The result is a lot of spinning blades but not much air
movement and a lot of wasted electricity. |
