Things to Know Before Buying an Outdoor
Ceiling Fan
Ceiling fans may look similar, but they are
not all created the same. You need to consider
many aspects of the ceiling fan that will best
meet your needs before making a selection. Some
considerations include the amount of air that is
being circulated as well as how efficient the
fan will move the air; the quietness (or
noisiness) of the fan; if the fan will wobble;
the durability of the fan's finish; the lifespan
of the fan and whether the manufacturer will
stand behind the warranty.
Some fans may have a nice appearance, but will
move very little air. Obviously, a fan such as
this would not be a good choice. Consider the
blade pitch of the fan as that is a major
component for air movement. Keep in mind that
the greater the pitch (angle of the blade), the
greater the air movement. The blade pitch must
also complement the motor for this to occur.
Some ceiling fan manufacturers will cut corners
on materials and will not use motors that are
powerful enough to sustain the correct blade
pitch. If blade pitch is compromised, proper air
movement will not occur because there will be
too much stress on a motor which is undersized
or under-powered. Some manufacturers may also
utilize very thin blades in order to reduce
costs, which also will result in decreased air
movement.
The entire effectiveness of a ceiling fan
depends upon the amount of energy it consumes,
as well as the volume of air that the fan moves.
Motors that are slow with low wattage utilize
very little energy, and as a result move very
little air, which makes them very inefficient.
If a ceiling fan is designed and manufactured
poorly, it could cause a humming noise when the
fan is operating. Often a humming noise is a
result of the use of cheap ball bearings, which
are installed to reduce costs. Another cause of
a humming noise (other annoying noise) could be
the result of improper dampening between the
metal parts of a fan or the use of a very thin
sheet metal motor or parts used to mount the
system.
