What length drop rod should I use with my fan? Will the fan be more prone to wobble if I use a drop rod? - See chart above. A general formula for calculating drop rod length is: ceiling height in feet minus 9 = drop rod length. This formula is based on the fan-to-floor distance of 8 feet plus 1 foot for the dimension of the fan. So if your ceiling height is 12 feet, you need a 3 foot drop rod in order to properly position the fan 8 feet from the floor. Using long-length drop rods for fan installations actually help stabilize fans and reduce the potential for wobble. Think of a grandfather clock pendulum and its slow, heavy swing versus a smaller clock pendulum with a fast, unsteady swing. Weight and length combine to create stability, reducing wobble, whether it is in a ceiling fan or a clock pendulum.
Some points to consider when buying a ceiling fan: - How much air is actually being circulated? - How efficiently will the fan move air? - How quiet or noisy is the fan? - Will the fan wobble? - How long will the fan last? - How durable is the finish? - Will the manufacturer stand behind the warranty?
How do fans cool the room - do they actually lower the temperature? A ceiling fan cools by creating a wind chill effect; it does not lower the room temperature. Wind chill effect makes you feel cooler by accelerating the evaporation of perspiration on your skin. It is the feeling you get when you open the window in a moving car. If you have a ceiling fan in a room whose temperature is 80 degrees, running the fan can create a wind chill effect that makes you feel as if the temperature is 72 degrees. When used in conjunction with an air conditioner, a ceiling fan can lower energy costs, because you can set the thermostat of your air conditioner at a higher temperature.
What is the difference between a four and five blade ceiling fan? The main difference between a 4-blade and 5-blade fan is aesthetics, with some additional wind noise associated with 5-blade fans. For a given motor, a 4-blade fan will move more air than a 5-blade fan. The 5th blade puts additional drag on the motor, slowing down the RPM of the blades, which decreases the CFM. All Hunter fans, whether 4 or 5 blades, are designed for optimal air delivery
Common Reasons Substandard Fans Break Down Prematurely. Motor size and blade pitch are not specified and matched correctly. Improperly installed on/off pull chains can become faulty and be pulled out of the housing. Inadequate quality, testing, manufacturing and inspection procedures send poor quality fans to market. Defective motor windings can lead to electrical shorts in the motor. Low quality fan bearings may be shielded on one side only, allowing dust to enter and cause premature failure. Inexpensive materials, poor engineering, and substandard manufacturing processes are used to create bargain fans.
Why Many Fans Are Less Efficient. The amount of energy a fan consumes plus the volume of air the fan moves determines the fans overall efficiency. Small, low wattage motors may use little energy, but they also move very little air, resulting in very inefficient fans, Hunter fans are built to shift a lot of air.
