Which Fans are the Best?

Below is our motor rating chart. The more powerful the motor...the more air your fan will move. The rest of this page has detailed information about things that make a huge difference in the quality and performance between fans.

Fan Motor Rating Chart
RATING	TYPE	DETAILS	PRICES
5	K55 XLP Cast-Iron	Hi-Performance Motors The most air movement possible. No wobble or noise. Can be left running 24 hours a day for a lifetime. We strongly recommend fans with this type of motor!	$300 to $1000 +
4	188mm	Very Good Performance Great air movement. Very little wobble or noise. Will last many years. Good for small to medium size rooms. 2nd most recommended!	$200 to $500
3	172mm	Above Average Acceptable air movement. Very slight noise. Very affordable. Recommended for smaller rooms if a higher quality fan is not affordable.	$150 to $350
2	153mm	Average Less air movement. Some noise or wobble over years of use. Recommended for contractors where projects require inexpensive fans.	$95 to $200
1	*Typical Import	Below Average Very little air movement. Annoying wobble and noise when new or within 1 or 2 years of use. Not recommended for any application.	Under $95

*Fans with smaller motors are typically found at home centers and mass merchants. We do not supply this type of fan at Home of Decor.

Important Note: Fans with extra wide palm leaf, wicker, or canvas type blades will only provide a gentle breeze and are considered to be more decorative than functional. Because this type of blade will tend to overwork an average fan motor we recommend that you choose only brands that offer these styles with Hi-Performance motors. Otherwise, your fan will overheat and start to make annoying noises and eventually burn out. (There is more this in the details below)

DETAILS: What makes some fans better than others?

The motor inside your fan is the most important component!

The most important consideration when purchasing a fan (aside from the way it looks) is the size, power, and durability of the motor. Larger more powerful motors are more expensive than smaller more generic mass produced motors...but they will move substantially more air without wobbling or making noise and can be left running for days, weeks, even years on end without burning out.

There are 5 major factors that work together to determine how much air a fan will move as well as it's overall performance and durability. The most important factor is the motor. A strong precision made motor will move the most air without noise or wobble if the other 4 factors are present.

The 5 basic factors are:

• Blade Pitch

• Blade Shape and Size

• RPM

• Height from Ceiling

• Motor

Looking more closely at each of these factors will show how they affect each other and why a fan with the most powerful motor can produce the most air movement.

1. Blade Pitch:
   The angle at which the blade sweeps through the air is called the "Pitch" of the blade. The easiest way to understand how blade pitch effects air movement is to equate the blades of a fan to the oars of a rowboat. If you have ever tried to row a  boat, you know that if you put the oars in the water virtually flat, it takes very little effort to row...but even if you row very fast, the boat moves very slow. If, on the other hand, you tilt the oars at a steep angle in the water, it becomes very difficult to row the boat...but each stroke makes substantial progress. You will need to be much stronger and in better shape to sustain a high rate of speed for any period of time in this case.
   
   The same is true with ceiling fans. Believe it or not, a fan spinning at a high RPM encounters substantial wind resistance if the blades are set at a steeper pitch. A fan that has blades with a very flat pitch (between 10 and 12 degrees), does not require a very powerful motor to make the blades spin fast. However, even at full speed, the fan will move very little air and may have a tendency to wobble or make noise.
   
   On the other hand, a good blade pitch (between 14 and 15 degrees) requires a well engineered finely tuned powerful motor to move the blades through the air at a high rate of speed for extended periods of time without overheating and burning out.
   
   Just as well, a good blade pitch with an average or lower grade motor will not be able to reach as high an RPM and may in fact be overworked resulting in a fan that overheats and eventually burns out.
   
   Therefore, the pitch of the blade and the power of the motor must be well engineered to work together to create air movement without going beyond the motors capability in order for a fan to operate efficiently and last a lifetime.
   
   

2. Blade Shape and Size
   Imagine rowing a boat with short narrow oars compared to wider longer oars. The wider and longer the oar is, the more effort it takes to pull it through the water. But once again, more effort means more progress. With ceiling fans, when you combine a wider longer blade with a steeper pitch, you get even more air movement...at least to a certain point.
   
   There is a limit to the shape and size that the oars or fan blades can and should be. If the oars or blades are too wide or too long, you will not be able to move maneuver them them fast enough no matter how strong you are. As with ceiling fans, blades that are too wide or long cannot be moved fast enough to be effective with even the most powerful fan motor. So...larger does not always mean better...but too small or narrow is not good.
   

3. RPM
   RPM is simply how fast your fan blades spin at a given speed setting. Faster means more air...but only if the blades are pitched properly. Also, some fans have a lower RPM at low speed and a higher RPM at high speed, which means they give you more flexibility in the cooling effect required. The best fans will give you 6 speeds from very low to very high.
   
   

4. Height from Ceiling
   In order for a fan to operate efficiently, there needs to be about 10 to 12 inches between the blades and the ceiling so that the air can flow freely around the blades without bouncing up and down between the blades and the ceiling. For this reason, you will find that ceiling hugger fans (fans that mount flush to the ceiling) don't move very much air. This type of fan will always have a small motor with relatively flat blades so that it does not create enough turbulence to cause it to wobble or shudder. You just won't find a "Hi-Performance" hugger fan.
   
   The blades on a typical hugger fan will be 7 or 8 inches from the ceiling as opposed to 10 to 12" for a good quality performance fan. The additional 2 or 3 inches makes all the difference in the world...kind of like having a tire on a car that is just a little out of balance. It may only take a small .5oz weight to balance the tire, but without the weight, the tire will bounce up and down like crazy at certain speeds. You should only use hugger fans if your ceilings are lower than 8' high or there is some other restriction (such as a bunk bed) that prevents you from installing a Hi-Performance fan that drops down a few more inches. 
   
   For higher ceilings, a longer downrod is recommended in order to bring the fan blades to about 8 or 9 feet from the floor so that you will feel the air movement.
   
   

5. Motor  - Size, Power, and Quality
   The motor is the most important component of a ceiling fan. The most powerful motors will move the most air, providing the above factors are present. High power fan motors are only available in the top of the line models from each of the major name brands. You will find these fans to be more expensive...but the difference in the amount of air you will feel is quite remarkable and the performance, durability, and efficiency is well worth the extra money.
   

Conclusion:
A well engineered ceiling fan takes all of the factors on this page into account, and with precision testing, a "Sweet Spot" is determined with the most efficient combination of blade pitch, shape and size of the blades, RPM, height from the ceiling, and most importantly, the capacity or capability of the motor.

The fans on our site that are rated 4 or 5, or are referred to as "Hi-Performance" are fans that are well engineered to the "Sweet Spot" and will give you the best performance for many years. We are sure you will be satisfied if you purchase one of these fans. We believe any other rating to be a compromise that manufacturers make in order to design fans to meet lower price points.
