Purchasing a ceiling fan can be an overwhelming choice with new models being launched everyday having state-of-art features. Our ultimate goal while buying a ceiling fan is to bring home a model which can guarantee maximum airflow. Today we are going to take a look at a few factors which can offer the same so that you bask in maximum comfort while bringing down your electricity bills:
Blade pitch is the angle of the blades while moving through the air. You can think of a ceiling fan’s blades to be similar to the oars of a rowboat. You can row a boat easily when the blades are flat to the water surface. However, the work becomes progressively tougher when the blades are tilted at a steeper angle. In such cases, you will have to work harder for covering a similar distance. This concept is also applicable in the case of a ceiling fan airflow. The fan blades require a relatively flat pitch between 10-12 degrees and not a very large motor for attaining a top speed. However, a more powerful motor will be required for achieving the same speed at a steeper blade pitch of 14-15 degrees. The fan witha flatter pitch might wobble and make noises from over-exhaustion while moving less air even at high speed. The fan with a steeper blade, on the other hand, isn’t adequately powerful and might wear out faster while trying to circulate larger amounts of air over prolonged timespans. Ideally, the power of the motor and the blade pitch needs to complement each other. Your fan will have to work harder but won’t be able to circulate more air if they work against each other. This will result in the motor burning out faster and offering less comfort to the homeowners. While you buy ceiling fans online, you need to check the product description offered by the manufacturer so that you can bring home the best product.
If you aim to increase the ceiling fan airflow, then the blades cannot be too wide or too long. Even if your fan has a big motor, it doesn’t necessarily mean that you should get a model having big blades. The blades and your fan motor need to be in harmony with each other to ensure the best air circulation.
RPM or rotations per minute is the speed at which the blades spin at a particular speed. Blades spinning faster move more air but only if the blades have the correct pitch. Your aim here should be to purchase a fan having separate speed setting from low to very high so that you can cater to your comfort quotient as the weather changes throughout the year.
For producing the best airflow, the ceiling fan’s blade should be around 10 to 12 inches from the ceiling. The only exception here is a hugger ceiling fan which is specially designed for hanging close to the ceiling. A fan that is too far from or close to the ceiling will fail to move as much air. You might be required to add a longer down-rod if you have vaulted ceilings so that the blades are positioned 8-9 feet from the floor.
If the above-mentioned factors are working in alignment, then the motor is undoubtedly the most important feature on your fan. You can depend on powerful motors to offer excellent comfort, durability, and airflow. Although the high-powered fans are more expensive, they can guarantee the best return on investment and a long lifespan.

The best way to gauge a ceiling fan’s air efficiency is by taking a look at its CFM or Cubic Feet per Minute. A higher number signifies more air circulation.
