Purchasing a Ceiling Fans
by: Stefan Rockhaus
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 for Your Ceiling Fan
Up to 75 sq. ft - Recommended fan size = 29-36 inches76-144 sq. ft - Recommended fan size = 36-42 inches
144-225 sq. ft - Recommended fan size = 44 inches225-400 sq. ft - Recommended fan size = 50-54 inches
Ceiling Fan 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 Ceiing Fan 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 Ceiling Fan 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 Ceiling Fan 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 Ceiling Fan: This is used for angled or domed ceilings.
Wet or Damp Rating of Ceiling Fans
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 Ceiling Fan Components
Ceiling Fan 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.
Ceiling Fan 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.
Ceiling Fan 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.
