Things To Consider While Purchasing A Ceiling Fan

The first artificial wind-chill methods as used by animals in nature was duplicated

by royalty and wealthy persons of early Assyria and Egypt, who employed slaves or servants waving large leaves to cool them down on hot days. Many centuries later, in 1882, Diehl introduced his invention of the electric ceiling fan. His device was a bubble-blade adaptation of the well known belt driven fan with an in-built electric motor. By the end of the 1880s, the "Diehl Electric" was sweeping the country, and by the late 1920s, no self-respecting restaurant, drug store, ice cream shop, or elegant dining room, was without a ceiling fan as part of their decor and method of ventilation.

First, the Fan Size and the size of the ceiling where you intend to fit it. Also measure the height of the ceiling and check if the blades have ample space to spin. It is better to keep two feet distance between the blades and the nearest wall.

Fan Size: It is important that the fan will fit in your room. You must consider the height of the ceiling and be sure that the blades have ample space in which to spin. It is recommended that the blades are no closer than two feet from the nearest wall.

The pitch range of the fan blade is between 8 to 15 degrees - the higher the pitch, the lower will be the efficiency of the circulation. The number of blades can vary from three to five, but it does not make much difference to the volume of air it produces.

Next is the Fan Motor. Make a query about the motor size; see whether the precision ground motor windings are matched to the length of the blades. The quality of the fan and circulation of the air depends mainly on this. It also ensures less consumption of energy. Vibrations will occur if the fans and blades are improperly balanced, even at slow speed. Fans particularly built for outdoor use have motors have specially designed to withstand moisture and fluctuations in temperature.

Fan Mounts: There are three main varieties of ceiling fan mounts - downrod mount, flush mount, and tri-mount. Fan Downrods can come at any length and are specially designed for rooms with higher ceilings, bringing the circulating blades of the fan down into the living space where it is most effective. A flush mount is designed for rooms with lower ceilings, and eliminates the need for a downrod. A tri-mount allows one to install a fan in a room for the best circulation whether there is a low, high or angled ceiling.
