Possible Ceiling Fan Issues
1. Fans that Move Small Amounts of Air
A ceiling fan that moves little air is useless. The pitch of the blade determines the amount of air moved. The pitch is the angle of the blade. Good quality materials are important in the construction of the fan. A strong motor is important to move the blades to push the air. Also, adequate thickness of blades is necessary.
2. Lack of Fan Efficiency
The fan’s efficiency is determined by the amount of energy consumed and the volume of air the fan moves. Therefore a small, low wattage motors which may use little energy, but consequently moves little air, is an inefficient fan.
3. Noisy Fans
Some fans have a hum created by the electrical workings of the fan. This is usually the result of a bad design and/or lack of precision manufacturing. For example, the use of inexpensive ball bearings can create an operating noise. Dampening material between metal parts can also create and intensify noise.
Fan wobble can be attributed to many factors. Cheap materials can produce blades that absorb moisture and warp, which is a prime source of wobble. Blades that are not carefully matched in weight and balanced can wobble. Poorly manufactured motors can easily get out of balance.
5. Premature Fan Break Down
A number of the above issues can singlely, or in concert, produce fan problems. Pull chains can break or be pulled from their housing. Poor quality and production standards can cause problems. Inexpensive motor parts can lead to motor electrical shorts. Inexpensive materials, poor engineering, and substandard manufacturing processes used to create economical fans can lead to problems.
