The Fundamentals Of Ceiling Fans

Ceiling fans are a basic necessity for the summer season.
However, there are certain things that must be remembered while
purchasing a ceiling fan.
 
To begin with, it is very essential to choose the right size of
fan, according to the room dimensions. Blade span of a ceiling
fan ranges from 29″ to 54″. The room where the ceiling fan is
to mounted must be measured. Here are certain recommended fan
sizes according to room dimensions:
 
Room Dimensions
 
Up to 75 sq. ft - Recommended fan size = 29-36 inches
76-144 sq. ft - Recommended fan size = 36-42 inches
144-225 sq. ft - Recommended fan size = 44 inches
225-400 sq. ft - Recommended fan size = 50-54 inches
 
Mounting Systems
 
It is recommended that the ceiling fan be mounted in the center
of the room. Also, it must be about seven feet from the ground
and about 18″ from the walls. If it is possible, install the
fan at the height of 8 to 9 feet from the ground.
 
Standard Mount: This is a three to five inch down rod (a metal
pipe that reaches to the top of the fan from the ceiling). The
diameter of the down rod is generally between 1.5″ to ¾”.
 
Extended Mount: This is used to hang the fan at an 8 to 9 foot
height from the floor if desired. These down rods are available
in about 6 to 120 inches. Ask the manufacture to determine the
right size of down rods according to your need.
 
Flush Mount: This anchors the fan right to the ceiling.
Generally, a standard fan can also be used as a flush mount;
but still, “hugger” or “low profile” ceiling fans are available
for the purpose.
 
Sloped Mount: This is used for angled or domed ceilings.
 
Wet or Damp Rating
 
When installing a ceiling fan in a bathroom or other humid
places, it is recommended to go for a fan that is UL “damp”
rated. When installing fans in a patio or front porch, look for
a “wet” rating, as they are exposed to water.
 
All the components of the fan together affect the working of
the fan and thus define the performance of the fan.
 
Other Components
 
Motor: There are two types of motors; one that is sealed and
lubricated, and another with oil ball bearings. There is hardly
any need of maintenance to the motors with sealed bearings,
while motors with an oil bath require frequent oiling.
 
Motor Housing: This is the decorative part of the fan, which
surrounds the fan motor. Fans with heavier materials are likely
to cause less vibration. This also provides more stability to
fans with longer down rods.
 
Other features that ensure longevity comprise of heavy-duty
windings, accurate engineering bearings and shock-absorbency.
These features are generally found in the expensive ceiling
fans.
 
Blades: The angle of the blades of a fan is called pitch. It is
determined in degrees. Blades with higher pitches move more air
that is provided in cubic feet per minute. However, it is
solely not responsible for the air movement. Other factors like
motor design as well as speed, blade design, and various others
affect the amount of air movement.
 
To provide variety in design, manufacturers offer a wide range
of blade styles in different models. However changing the blade
style can negatively affect the fan’s performance.
